1. Introduction

MediaTomb is an open source (GPL) UPnP MediaServer with a nice web user
interface, it allows you to stream your digital media through your home network
and listen to/watch it on a variety of UPnP compatible devices.

MediaTomb implements the UPnP MediaServer V 1.0 specification that can be found
on http://www.upnp.org/. The current implementation focuses on parts that are
required by the specification, however we look into extending the functionality
to cover the optional parts of the spec as well.

MediaTomb should work with any UPnP compliant MediaRenderer, please tell us if
you experience difficulties with particular models, also take a look at the
Supported Devices list for more information.

WARNING!

The server has an integrated file system browser in the UI, that means that
anyone who has access to the UI can browse your file system (with user
permissions under which the server is running) and also download your data! If
you want maximum security - disable the UI completely! Account authentication
offers simple protection that might hold back your kids, but it is not secure
enough for use in an untrusted environment!

Note:

    since the server is meant to be used in a home LAN environment the UI is
    enabled by default and accounts are deactivated, thus allowing anyone on
    your network to connect to the user interface.

1.1. Currently Supported Features

  * browse and playback your media via UPnP

  * metadata extraction from mp3, ogg, flac, jpeg, etc. files.

  * Exif thumbnail support

  * user defined server layout based on extracted metadata (scriptable virtual
    containers)

  * automatic directory rescans

  * sophisticated web UI with a tree view of the database and the file system,
    allowing to add/remove/edit/browse your media

  * highly flexible media format transcoding via plugins / scripts

  * allows to watch YouTube(tm) videos on your UPnP player device

  * support for external URLs (create links to internet content and serve them
    via UPnP to your renderer)

  * support for ContentDirectoryService container updates

  * Active Items (experimental feature), allows execution of server side
    scripts upon HTTP GET requests to certain items

  * highly flexible configuration, allowing you to control the behavior of
    various features of the server

  * support for Linux, FreeBSD, Mac OS X

  * runs on x86, Alpha, ARM, MIPS, Sparc, PowerPC

2. Requirements

Note:

    remember to install associated development packages, because development
    headers are needed for compilation!

Note:

    libupnp is now a part of MediaTomb and does not have to be installed
    separately. We base our heavily patched version on libupnp 1.4.1 from http:
    //pupnp.sf.net/

Note:

    you need at least one database in order to compile and run MediaTomb -
    either sqlite or mysql.

In order to compile MediaTomb you will have to install the following packages.:

  * sqlite (version > 3.x) http://www.sqlite.org/ REQUIRED (if mysql is not
    available)

  * mysql client library (version > 4.0.x) http://mysql.org/ REQUIRED (if
    sqlite is not available)

  * expat http://expat.sourceforge.net/ REQUIRED

    Expat is a very good and robust XML parser, since most of UPnP is based on
    XML this package is a requirement.

  * zlib http://www.zlib.net/ OPTIONAL, HIGHLY RECOMMENDED

    Zlib is a compression library that is available on most systems, we need it
    for the database autocreation functionality. Make sure to install the zlib
    development package providing zlib.h, if it is not available you will need
    to create the MediaTomb sqlite3/MySQL database manually.

  * libmagic OPTIONAL, RECOMMENDED

    This is the 'file' package, it is used to determine the mime type of the
    media. If you don't have this you will have to enter file extension to mime
    type mappings manually in your config file.

  * js - SpiderMonkey JavaScript Engine http://www.mozilla.org/js/spidermonkey/
    OPTIONAL, RECOMMENDED, REQUIRED FOR PLAYLIST SUPPORT

    This package is necessary to allow the user defined creation of virtual
    containers. The import.js script defines the layout of your media, the
    default import script will create a structure sorted by Audio/Photo/Video,
    it will make use of the gathered metadata (like ID3 tags) to sort your
    music by Artist/Album/Genre/Year , etc. The import script can be adjusted
    and modified - it allows you to create the layout that you want.

  * taglib http://developer.kde.org/~wheeler/taglib.html OPTIONAL, RECOMMENDED

    This library retrieves metadata from mp3, ogg and flac files. You will need
    it if you want to have virtual objects for those files (i.e. nice content
    layout).

    Note:

        It makes no sense to use taglib and id3lib at the same time, the
        configure script will first look for TagLib, if TagLib detection fails
        it will search for id3lib. You can also force the configure script to
        take the library of your choice, overriding the default setting.

  * id3lib http://id3lib.sourceforge.net/ (at least version 3.8.3) OPTIONAL,
    RECOMMENDED (if TagLib is not available)

    This library retrieves id3 tags from mp3 files.

  * libexif http://libexif.sourceforge.net/ OPTIONAL, RECOMMENDED

    You will need this library if you want to extract metadata from images,
    this will allow you to have virtual containers for your Photos, sorted by
    various attributes like Date, etc. It also enables thumbnail support: if
    EXIF thumbnails are present in your images they will also be offered via
    UPnP.

  * curl http://curl.haxx.se/ OPTIONAL, REQUIRED FOR YOUTUBE AND SOPCAST
    SUPPORT

    curl is a library that allows to easily fetch content from the web, if you
    want to compile MediaTomb with YouTube and/or SopCast support then curl is
    required.

  * libextractor http://gnunet.org/libextractor/ OPTIONAL

    This library tries to gather metadata from all kinds of files (also .avi
    and .asf). The drawback is, that it can be very slow at scanning video
    files. We also noticed that it uses a lot of memory when reading files, the
    result is, that media import becomes extremely slow. It is up to you if you
    want to use it or not, you may try the 'extract' utility that is provided
    with the library to check if there is any metadata that can be extracted
    from your media prior to enabling this feature in MediaTomb. By default
    libextractor is disabled, use ./configure --enable-libextractor to activate
    it.

  * ffmpeg http://ffmpeg.mplayerhq.hu/ OPTIONAL

    Currently ffmpeg is used to gather additional metadata from audio and video
    files.

  * libffmpegthumbnailer http://code.google.com/p/ffmpegthumbnailer/ OPTIONAL

    ffmpegthumbnailer is used to generate video thumbnails on the fly. If your
    device (like DSM-510 or PlayStation 3) supports video thumbnails it would
    be worth to compile MediaTomb with this library.

    Note:

        ffmpegthumbnailer support is only provided if MediaTomb is compiled
        with ffmpeg support.

In order to use the web UI you will need to have javascript enabled in your web
browser.

The UI has been tested and works with the recent versions of :

  * Firefox/Mozilla

  * Opera

Tested and does not work with the recent versions of:

  * Konqueror

  * Safari

Limited functionality with:

  * Internet Explorer 6 and 7

3. Compiling From Source

3.1. Standard Method

If you don't care about the details - make sure you have installed the required
packages and the appropriate development headers and simply run

$ ./configure
$ make
$ make install

This should compile and install MediaTomb, the resulting binary is ready to
run.

Note:

    if you checked out the sources from SVN the configure script will not be
    available, you will have to create it with the following command:

autoreconf -i

3.2. Configure Options

The MediaTomb configure script provides a large variety of options, allowing
you to specify the additional libraries that will be used, features that will
be compiled or disabled, workarounds for known bugs in some distributions and
so on. Some options are straightforward, some require deeper knowledge - make
sure you know what you are doing :)

3.2.1. Install Location Of Architecture Independent Files

--prefix=PREFIX

Default:

    /usr/local/

Install all architecture independent files - all .js files and .png images for
the Web UI, the import.js script, the service description XML files - in the
directory of your choice. This is especially useful if you do not want to
perform a system-wide installation, but want to install MediaTomb only for your
user.

Important:

    the prefix path will be compiled into the binary; the binary will still be
    relocatable, but you move those files you will have to point MediaTomb to
    the proper location by specifying it in the server configuration file.

3.2.2. Static Build

--enable-static

Default:

    disabled

Build a static binary. This may be useful if you plan to install a precompiled
MediaTomb binary on a system that does not have all the required libraries and
where installation of those libraries is not possible due to reasons beyond
your control.

Note:

    if you enable this option, make sure that you have all static versions of
    the appropriate libraries installed on your system. The configure script
    may not detect that those are missing - in this case you will get linker
    errors. Some distributions, for example Fedora Core, do not ship static
    library versions.

3.2.3. Automatically Create Database

--enable-db-autocreate

Default:

    enabled

Automatically create the database if it is missing (for example upon a first
time launch). Disabling this will make the resulting binary a little smaller,
however you will have to take care of the database creation yourself by
invoking the appropriate .sql scripts that are provided with the package.

Note:

    the server configuration file has to be setup correctly. Either sqlite or
    MySQL has to be chosen in the storage section, for sqlite the database file
    has to point to a writable location, for MySQL the user has to be setup
    with a valid password and permissions and the database "mediatomb" has to
    exist.

3.2.4. Debug Malloc/Realloc Of Zero bytes

--enable-debug-malloc0

Default:

    disabled

This feature is only for debugging purposes, whenever a malloc or realloc with
a value of zero bytes is encountered, the server will terminate with abort()

3.2.5. Force Linking With The Pthread Library

--enable-pthread-lib

Default:

    disabled

We use the ACX_PTHREAD macro from the autoconf archive to determine the way how
to link against the pthread library. Usually it works fine, but it can fail
when cross compiling. This configure option tells us to use -lpthread when
linking, it seems to be needed when building MediaTomb under Optware. Note,
that using --disable-pthread-lib will not prevent automatic checks against the
pthread library.

3.2.6. Force Linking With The Iconv Library

--enable-iconv-lib

Default:

    disabled

By default we will attempt to use iconv functionality provided with glibc,
however under some circumstances it may make sense to link against a separate
iconv library. This option will attempt to do that. Note, that using
--disable-iconv-lib will not prevent automatic attempts to link ageinst the
iconv library in the case where builtin glibc iconv functionality is not
available.

3.2.7. Use Atomic Assembler Code For x86 Single CPU systems

--enable-atomic-x86-single

Default:

    disabled

Use assembler code suited for single CPU x86 machines. This may improve
performance, but your binary will not function properly on SMP systems. If you
specify this for a non x86 architecture the binary will not run at all. If you
wonder about the purpose of assembler code in a mediaserver application: we
need it for atomic operations that are required for reference counting. The
pthread library will be used as a fallback for other architectures, but can
also be forced by a designated configure option. This however, will have the
worst performance.

By default x86 SMP code will be used on x86 systems - it will reliably work on
both SMP and single CPU systems, but will not be as fast as the
atomic-x86-single option on uniprocessor machines.

3.2.8. Use Pthread Code For Atomic Operations

--enable-atomic-pthread

Default:

    auto detect

This is the default setting for non x86 architectures, we may add assembler
optimizations for other architectures as well, but currently only x86
optimizations are available. This option may also be safely used on x86
machines - the drawback is poor performance, compared to assembler optimized
code.

3.2.9. Enable SIGHUP Handling

--enable-sighup

This option turns on SIGHUP handling, every time a SIGHUP is caught we will
attempt to restart the server and reread the configuration file. By default
this feature is enabled for x86 platforms, but is disabled for others. We
discovered that MediaTomb will not cleanly restart on ARM based systems,
investigations revealed that this is somehow related to an unclean libupnp
shutdown. This will be fixed in a later release.

Default:

    auto detect

3.2.10. X_MS_MediaReceiverRegistrar Support

--enable-mrreg-service

Default:

    disabled

This option will enable the compilation and support of the
X_MS_MediaReceiverRegistrar UPnP service, this was implemented for future Xbox
360 support. If you have a renderer that requires this service, you can safely
enable it. It will always return true to IsValidated and IsAuthorized requests.

Note:

    eventhough this service is implemented there is still no Xbox 360 support
    in MediaTomb, more work needs to be done.

3.2.11. Playstation 3 Support

--enable-protocolinfo-extension

Default:

    enabled

This option allows to send additional information in the protocolInfo
attribute, this will enable MP3 and MPEG4 playback for the Playstation 3, but
may also be useful to some other renderers.

Note:

    allthough compiled in, this feature is disabled in configuration by
    default.

3.2.12. Fseeko Check

--disable-fseeko-check

Default:

    enabled

This is a workaround for a bug in some Debian distributions, disable this check
if you know that your system has large file support, but configure fails to
detect it.

3.2.13. Largefile Support

--disable-largefile

Default:

    auto

By default largefile support will be auto detected by configure, however you
can disable it if you do not want it or if you experience problems with it on
your system.

3.2.14. Redefinition Of Malloc And Realloc

--disable-rpl-malloc

Default:

    enabled

Autoconf may redefine malloc and realloc functions to rpl_malloc and
rpl_realloc, usually this will happen if the autotools think that you are
compiling against a non GNU C library. Since malloc and realloc may behave
different on other systems, this gives us the opportunity to write wrapper
functions to handle special cases. However, this redefinition may get triggered
when cross compiling, even if you are compiling against the GNU C lib. If this
is the case, you can use this option to disable the redefinition.

3.2.15. SQLite Support

--enable-sqlite3

Default:

    enabled

The SQLite database is very easy in installation and use, you do not have to
setup any users, permissions, etc. A database file will be simply created as
specified in the MediaTomb configuration. At least SQLite version 3 is
required.

3.2.16. MySQL Support

--enable-mysql

Default:

    enabled

MySQL is a very powerful database, however it requires some additional setup.
You will find information on how to setup MediaTomb with MySQL in the
Installation section.

3.2.17. SpiderMonkey LibJS Support

--enable-libjs

Default:

    enabled

SpiderMonkey is Mozilla's JavaScript engine, it plays a very important role in
MediaTomb. We use it to create a nice virtual container layout based on the
metadata that is extracted from your media. We also allow the user to create
custom import scripts, so everyone has the possibility to adapt the layout to
ones personal needs. Read more about this in the installation section.

The main problem with this library is, that it is called differently on various
distributions and that it is installed in different locations. For example, it
is called js on Fedora, but is available under the name of smjs on Debian. If
configure fails to find your js headers and libraries you can point it to the
desired locations (see options below).

3.2.18. Filemagic Support

--enable-libmagic

Default:

    enabled

This library determines the file type and provides us with the appropriate mime
type information. It is very important to correctly determine the mime type of
your media - this information will be sent to your renderer. Based on the mime
type information, the renderer will decide if it can play/display the
particular file or not. If auto detection returns strange mime types, you may
want to do a check using the 'file' command (the 'file' package must be
installed on your system). Assuming that you want to check somefile.avi enter
the following in your terminal:

$ file -i somefile.avi

This will print the detected mime type, this is exactly the information that we
use in MediaTomb. You can override auto detection by defining appropriate file
extension to mime type mappings in your configuration file. You can also edit
the mime type information of an imported object manually via the web UI.

3.2.19. Id3lib Support

--enable-id3lib

Default:

    disabled, used if taglib is not available

This library will parse id3 tags of your MP3 files, the gathered information
will be saved in the database and provided via UPnP. Further, the gathered
metadata will be used by the import script to create a nice container layout
(Audio/Artist/Album, etc.)

3.2.20. Taglib Support

--enable-taglib

Default:

    enabled, preffered over id3lib

This library will parse id3 tags of your MP3 files as well as information
provided with flac files. It claims to be faster than id3lib, but it also seems
to have some drawbacks. We had some cases where it crashed when trying to parse
tags of certain MP3 files on embedded systems, we had reports and observed that
it had problems parsing the sample rates. We also did some valgrinding and
detected memory leaks. Our feeling is, that you will have more stable results
with id3lib, however it is up to you to enable or disable this library. By
default id3lib will be taken if both libraries are present on the system.

3.2.21. Libexif Support

--enable-libexif

Default:

    enabled

The exif library will gather metadata from your photos, it will also find exif
thumbnails which are created automatically by most digital camera models. The
gathered data will be used by the import script, the thumbnails will be offered
as additional resources via UPnP.

3.2.22. Libextractor Support

--enable-libextractor

Default:

    disabled

Libextractor is a library that attempts to parse all sorts of files, this
includes exif data, id3 tags and much more. It can also deal with .AVI and .ASF
files which is useful when your video files have the appropriate metadata. The
drawback is - it is slow, especially slow on scanning big video files, so it
slows down the import process considerably. For this reason this library is
disabled by default.

3.2.23. Inotify Support

--enable-inotify

Default:

    auto

Inotify is a kernel mechanism that allows monitoring of filesystem events. You
need this if you want to use the Inotify Autoscan mode, contrary to the Timed
mode which recsans given directories in specified intervals, Inotify mode will
immedeately propagate changes in monitored directories on the filesystem to the
database.

If you do not specify this option configure will check if inotify works on the
build system and compile it in only if the check succeeds. If you specify this
option, the functionality will be compiled in even if the build system does not
support inotify - the availability of inotify will then be checked at server
runtime.

3.2.24. YouTube Service Support

--enable-youtube

Default:

    enabled

This option enabled support of the YouTube service, it allows to gather
information about content on the YouTube site and offers the content via UPnP,
thus enabling you to watch your favorite YouTube videos on your UPnP player
device. The feature only makes sense in combination with transcoding, since
most devices do not support playback of flv files natively.

3.2.25. External Transcoding

--enable-external-transcoding

Default:

    enabled

3.2.26. Sqlite Backup Defaults

--enable-sqlite-backup-defaults

Default:

    disabled

Enables backup option for sqlite as the default setting, might be useful for
NAS builds.

3.2.27. Curl

--enable-curl

Default:

    enabled if external transcoding or YouTube features are turned on

It only makes sense to enable the curl library if YouTube and External
Transcoding are turned on. YouTube requires curl, but it's optional for
External Transcoding.

3.2.28. Ffmpeg Support

--enable-ffmpeg

Default:

    enabled

Currently the ffmpeg library is used to extract additional information from
audio and video files. It is also capable of reading out the tag information
from theora content. It is not yet used for transcoding, so this feature only
gathers additional metadata.

3.2.29. Ffmpeg Thumbnailer Support

--enable-ffmpegthumbnailer

Default:

    enabled

Compiling with ffmpegthumbnailer support is only possible if you also compile
with ffmpeg support. The library allows to generate thumbnails for the videos
on the fly.

3.2.30. MediaTomb Debug Output

--enable-tombdebug

Default:

    disabled

This option enables debug output, the server will print out a lot of
information which is mainly interesting to developers. Use this if you are
trying to trace down a bug or a problem, the additional output may give you
some clues.

3.2.31. UPnP Library Debug Output

--enable-upnpdebug

Default:

    disabled

This option enables debug output of the UPnP SDK. You should not need it under
normal circumstances.

3.2.32. Log Output

--disable-log

Default:

    enabled

This option allows you to suppress all log output from the server.

3.2.33. Debug Log Output

Default:

    enabled

This option allows you to compile the server with debug messages. If enabled,
switching between verbose and normal output during runtime becomes possible.

3.2.34. Package Search Directory

--with-search=DIR

Default:

    /opt/local/ on Darwin, /usr/local/ on all other systems

Some systems may have whole sets of packages installed in an alternative
location, for example Darwinports on OSX get installed to /opt/local/. This
option tells the configure script to additionally search for headers and
libraries of various packages in DIR/include and DIR/lib.

3.2.35. Specifying Header And Library Locations Of Various Packages

You can specify the exact location of particular headers and libraries. Some
packages use extra programs that tell us the appropriate flags that are needed
for compilation - like mysql_config. You can also specify the exact location of
those programs. The parameters are self explanatory, in case of headers and
libraries the DIR parameter is the directory where those headers and libraries
are located.

--with-sqlite3-h=DIR               search for sqlite3 headers only in DIR
--with-sqlite3-libs=DIR            search for sqlite3 libraries only in DIR
--with-mysql-cfg=mysql_config      absolute path/name of mysql_config
--with-js-h=DIR                    search for js (spidermonkey) headers in DIR
--with-js-libs=DIR                 search for js (spidermonkey) libraries in DIR
--with-libmagic-h=DIR              search for filemagic headers in DIR
--with-libmagic-libs=DIR           search for filemagic headers in DIR

--with-libexif-libs=DIR            search for libexif libraries in DIR
--with-expat-h=DIR                 search for expat headers in DIR
--with-expat-libs=DIR              search for expat libraries in DIR
--with-taglib-cfg=taglib-config    absolute path/name of taglib-config
--with-id3lib-h=DIR                search for id3lib headers in DIR
--with-id3lib-libs=DIR             search for id3lib libraries in DIR
--with-zlib-h=DIR                  search for zlib headers in DIR
--with-zlib-libs=DIR               search for zlib libraries in DIR
--with-inotify-h=DIR               search for inotify header in DIR
--with-iconv-h=DIR                 search for iconv headers in DIR/sys
--with-iconv-libs=DIR              search for iconv libraries in DIR

--with-rt-libs=DIR                 search for rt libraries in DIR
--with-pthread-libs=DIR            search for pthread libraries in DIR


3.2.36. The devconf Script

If you are doing some development work and some debugging, you will probably
want to compile with the -g flag and also disable optimization. The devconf
script does exactly that. In addition, it accepts command line parameters that
are passed to the configure script.

4. Initial Installation

4.1. Network Setup

Some systems require a special setup on the network interface. If MediaTomb
exits with UPnP Error -117, or if it does not respond to M-SEARCH requests from
the renderer (i.e. MediaTomb is running, but your renderer device does not show
it) you should try the following settings (the lines below assume that
MediaTomb is running on a Linux machine, on network interface eth1):

# route add -net 239.0.0.0 netmask 255.0.0.0 eth1
# ifconfig eth1 allmulti

Those settings will be applied automatically by the init.d startup script.

You should also make sure that your firewall is not blocking port UDP port 1900
(required for SSDP) and UDP/TCP port of MediaTomb. By default MediaTomb will
select a free port starting with 49152, however you can specify a port of your
choice in the configuration file.

4.2. First Time Launch

When starting MediaTomb for the first time, a .mediatomb directory will be
created in your home. Further, a default server configuration file, called
config.xml will be generated in that directory.

4.2.1. Using Sqlite Database

If you are using sqlite - you are ready to go, the database file will be
created automatically and will be located ~/.mediatomb/mediatomb.db If needed
you can adjust the database file name and location in the server configuration
file.

4.2.2. Using MySQL Database

If MediaTomb was compiled with support for both databases, sqlite will be
chosen as default because the initial database can be created and used without
any user interaction. If MediaTomb was compiled only with MySQL support, the
appropriate config.xml file will be created in the ~/.mediatomb directory, but
the server will then terminate, because user interaction is required.

MediaTomb has to be able to connect to the MySQL server and at least the
(empty) database has to exist. To create the database and provide MediaTomb
with the ability to connect to the MySQL server you need to have the
appropriate permissions. Note that user names and passwords in MySQL have
nothing to do with UNIX accounts, MySQL has it's own user names/passwords.
Connect to the MySQL database as "root" or any other user with the appropriate
permissions:

$ mysql [-u <username>] [-p]

(You'll probably need to use "-u" to specify a different MySQL user and "-p" to
specify a password.)

Create a new database for MediaTomb: (substitute "<database name>" with the
name of the database)

mysql> CREATE DATABASE <database name>;

(You can also use "mysqladmin" instead.)

Give MediaTomb the permissions to access the database:

mysql> GRANT ALL ON <database name>.*
       TO '<user name>'@'<hostname>'
       IDENTIFIED BY '<password>';

If you don't want to set a password, omit "IDENTIFIED BY .." completely. You
could also use the MySQL "root" user with MediaTomb directly, but this is not
recommended.

To create a database and a user named "mediatomb" (who is only able to connect
via "localhost") without a password (the defaults) use:

mysql> CREATE DATABASE mediatomb;
mysql> GRANT ALL ON mediatomb.* TO 'mediatomb'@'localhost';

If MediaTomb was compiled with database auto creation the tables will be
created automatically during the first startup. All table names have a "mt_"
prefix, so you can theoretically share the database with a different
application. However, this is not recommended.

If database auto creation wasn't compiled in (configure was run with the
"--disable-db-autocreate" or zlib.h was not available) you have to create the
tables manually:

$ mysql [-u <username>] [-p] \
  <database name> < \
  <install prefix>/share/mediatomb/mysql.sql

After creating the database and making the appropriate changes in your
MediaTomb config file you are ready to go - launch the server, and everything
should work.

5. Command Line Options

There is a number of options that can be passed via command line upon server
start up, for a short summary you can invoke MediaTomb with the following
parameter:

$ mediatomb --help

Note:

    the command line options override settings in the configuration file!

5.1. IP Address

--ip or -i

The server will bind to the given IP address, currently we can not bind to
multiple interfaces so binding to 0.0.0.0 will not be possible.

5.2. Interface

--interface or -e

Interface to bind to, for example eth0, this can be specified instead of the ip
address.

5.3. Port

--port or -p

Specify the server port that will be used for the web user interface, for
serving media and for UPnP requests, minimum allowed value is 49152. If this
option is omitted a default port will be chosen, however, in this case it is
possible that the port will change upon server restart.

5.4. Configuration File

 --config or -c

By default MediaTomb will search for a file named "config.xml" in the ~
/.mediatomb directory. This option allows you to specify a config file by the
name and location of your choice. The file name must be absolute.

5.5. Daemon Mode

--daemon or -d

Run the server in background, MediaTomb will shutdown on SIGTERM, SIGINT and
restart on SIGHUP.

5.6. Home Directory

--home or -m

Specify an alternative home directory. By default MediaTomb will try to
retrieve the users home directory from the environment, then it will look for a
.mediatomb directory in users home. If .mediatomb was found we will try to find
the default configuration file (config.xml), if not found we will create both,
the .mediatomb directory and the default config file.

This option is useful in two cases: when the home directory can not be
retrieved from the environment (in this case you could also use -c to point
MediaTomb to your configuration file or when you want to create a new
configuration in a non standard location (for example, when setting up daemon
mode). In the latter case you can combine this parameter with the parameter
described in Section 5.7, "Config Directory"

5.7. Config Directory

--cfgdir or -f

The default configuration directory is combined out of the users home and the
default that equals to .mediatomb, this option allows you to override the
default directory naming. This is useful when you want to setup the server in a
nonstandard location, but want that the default configuration to be written by
the server.

5.8. Write PID File

--pidfile or -P

Specify a file that will hold the server process ID, the filename must be
absolute.

5.9. Run Under Different User Name

--user or -u

Run MediaTomb under the specified user name, this is especially useful in
combination with the daemon mode.

5.10. Run Under Different Group

--group or -g

Run MediaTomb under the specified group, this is especially useful in
combination with the daemon mode.

5.11. Add Content

--add or -a

Add the specified directory or file name to the database without UI
interaction. The path must be absolute, if path is a directory then it will be
added recursively. If path is a file, then only the given file will be
imported.

5.12. Log To File

--logfile or -l

Do not output log messages to stdout, but redirect everything to a specified
file.

5.13. Debug Output

--debug or -D

Enable debug log output.

5.14. Compile Info

--compile-info

Print the configuration summary (used libraries and enabled features) and exit.

5.15. Version Information

--version

Print version information and exit.

5.16. Display Command Line Summary

--help or -h

Print a summary about the available command line options.

6. Configuration File

MediaTomb is highly configurable and allows the user to set various options and
preferences that define the servers behavior. Rather than enforcing certain
features upon the user, we prefer to offer a number of choices where possible.
The heart of MediaTomb configuration is the config.xml file, which is located
in the ~/.mediatomb directory. If the configuration file is not found in the
default location and no configuration was specified on the command line,
MediaTomb will generate a default config.xml file in the ~/.mediatomb
directory. The file is in the XML format and can be edited by a simple text
editor, here is the list of all available options:

  * "Required" means that the server will not start if the tag is missing in
    the configuration.

  * "Optional" means that the tag can be left out of the configuration file.

The root tag of MediaTomb configuration is:

<config>

6.1. Server Settings

These settings define the server configuration, this includes UPnP behavior,
selection of database, accounts for the UI as well as installation locations of
shared data.

<server>

Required

This section defines the server configuration parameters.

Child tags:

  * <port>0</port>

    Optional

    Default: 0 (automatic)

    Specifies the port where the server will be listening for HTTP requests.
    Note, that because of the implementation in the UPnP SDK only ports above
    49152 are supported. The value of zero means, that a port will be
    automatically selected by the SDK.

  * <ip>192.168.0.23</ip>

    Optional

    Default: ip of the first available interface.

    Specifies the IP address to bind to, by default one of the available
    interfaces will be selected.

  * <interface>eth0</interface>

    Optional

    Default: first available interface.

    Specifies the interface to bind to, by default one of the available
    interfaces will be selected.

  * <name>MediaTomb</name>

    Optional

    Default: MediaTomb

    Server friendly name, you will see this on your devices that you use to
    access the server.

  * <manufacturerURL>http://mediatomb.org/</manufacturerURL>

    Optional

    Default: http://mediatomb.cc/

    This tag sets the manufacturer URL of a UPnP device, a custom setting may
    be necessary to trick some renderers in order to enable special features
    that otherwise are only active with the vendor implemented server.

  * <modelName>MediaTomb</modelName>

    Optional

    Default: MediaTomb

    This tag sets the model name of a UPnP device, a custom setting may be
    necessary to trick some renderers in order to enable special features that
    otherwise are only active with the vendor implemented server.

  * <modelNumber>0.9.0</modelNumber>

    Optional

    Default: MediaTomb version

    This tag sets the model number of a UPnP device, a custom setting may be
    necessary to trick some renderers in order to enable special features that
    otherwise are only active with the vendor implemented server.

  * <serialNumber>1</serialNumber>

    Optional

    Default: 1

    This tag sets the serial number of a UPnP device.

  * <presentationURL append-to="ip">80/index.html</presentationURL>

    Optional

    Default: "/"

    The presentation URL defines the location of the servers user interface,
    usually you do not need to change this however, vendors who want to ship
    our server along with their NAS devices may want to point to the main
    configuration page of the device.

    Attributes:

      o append-to=...

        Optional

        Default: "none"

        The append-to attribute defines how the text in the presentationURL tag
        should be treated.

        The allowed values are:

        append-to="none"

        Use the string exactly as it appears in the presentationURL tag.

        append-to="ip"

        Append the string specified in the presentationURL tag to the ip
        address of the server, this is useful in a dynamic ip environment where
        you do not know the ip but want to point the URL to the port of your
        web server.

        append-to="port"

        Append the string specified in the presentationURL tag to the server ip
        and port, this may be useful if you want to serve some static pages
        using the built in web server.

  * <udn/>

    Required

    Default: automatically generated if the tag is empty

    Unique Device Name, according to the UPnP spec it must be consistent
    throughout reboots. You can fill in something yourself, but we suggest that
    you leave this tag empty - it will be filled out and saved automatically
    after the first launch of the server.

  * <home>/home/your_user_name/.mediatomb</home>

    Required

    Default: ~/.mediatomb

    Server home - the server will search for the data that it needs relative to
    this directory - basically for the sqlite database file. The mediatomb.html
    bookmark file will also be generated in that directory.

  * <webroot>/usr/share/mediatomb/web</webroot>

    Required

    Default: depends on the installation prefix that is passed to the configure
    script.

    Root directory for the web server, this is the location where device
    description documents, UI html and js files, icons, etc. are stored.

  * <servedir>/home/myuser/mystuff</servedir>

    Optional

    Default: empty (disabled)

    Files from this directory will be served as from a regular web server. They
    do not need to be added to the database, but they are also not served via
    UPnP browse requests. Directory listing is not supported, you have to
    specify full paths.

    Example:

        the file something.jar is located in /home/myuser/mystuff/javasubdir/
        something.jar on your filesystem. Your ip address is 192.168.0.23, the
        server is running on port 50500. Assuming the above configuration you
        could download it by entering this link in your web browser: http://
        192.168.0.23:50500/content/serve/javasubdir/something.jar

  * <alive>180</alive>

    Optional

    Default: 180, this is according to the UPnP specification.

    Interval for broadcasting SSDP:alive messages

  * <protocolInfo extend="no"/>

    Optional

    Default: no

    Adds specific tags to the protocolInfo attribute, this is required to
    enable MP3 and MPEG4 playback on Playstation 3.

  * <pc-directory upnp-hide="no"/>

    Optional

    Default: no

    Enabling this option will make the PC-Directory container invisible for
    UPnP devices.

    Note:

        independent of the above setting the container will be always visible
        in the web UI!

  * <tmpdir>/tmp/</tmpdir>

    Optional

    Default: /tmp/

    Selects the temporary directory that will be used by the server.

  * <bookmark>mediatomb.html</bookmark>

    Optional

    Default: mediatomb.html

    The bookmark file offers an easy way to access the user interface, it is
    especially helpful when the server is not configured to run on a fixed
    port. Each time the server is started, the bookmark file will be filled in
    with a redirect to the servers current IP address and port. To use it,
    simply bookmark this file in your browser, the default location is ~
    /.mediatomb/mediatomb.html

  * <custom-http-headers>

    Optional

    This section holds the user defined HTTP headers that will be added to all
    HTTP responses that come from the server.

    Child tags:

      o <add header="..."/>
        <add header="..."/>
        ...

        Optional

        Specify a header to be added to the response. If you have a DSM-320 use
        <add header="X-User-Agent: redsonic"/> to fix the .AVI playback
        problem.

  * <upnp-string-limit>

    Optional

    Default: disabled

    This will limit title and description length of containers and items in
    UPnP browse replies, this feature was added a s workaround for the TG100
    bug which can only handle titles no longer than 100 characters. A negative
    value will disable this feature, the minimum allowed value is "4" because
    three dots will be appended to the string if it has been cut off to
    indicate that limiting took place.

  * <ui enabled="yes" poll-interval="2" poll-when-idle="no"/>

    Optional

    This section defines various user interface settings.

    WARNING!

    The server has an integrated filesystem browser, that means that anyone who
    has access to the UI can browse your filesystem (with user permissions
    under which the server is running) and also download your data! If you want
    maximum security - disable the UI completely! Account authentication offers
    simple protection that might hold back your kids, but it is not secure
    enough for use in an untrusted environment!

    Note:

        since the server is meant to be used in a home LAN environment the UI
        is enabled by default and accounts are deactivated, thus allowing
        anyone on your network to connect to the user interface.

    Attributes:

      o enabled=...

        Optional

        Default: yes

        Enables ("yes") or disables ("no") the web user interface.

      o show-tooltips=...

        Optional

        Default: yes

        This setting specifies if icon tooltips should be shown in the web UI.

      o poll-interval=...

        Optional

        Default: 2

        The poll-interval is an integer value which specifies how often the UI
        will poll for tasks. The interval is specified in seconds, only values
        greater than zero are allowed.

      o poll-when-idle=...

        Optional

        Default: no

        The poll-when-idle attribute influences the behavior of displaying
        current tasks: - when the user does something in the UI (i.e. clicks
        around) we always poll for the current task and will display it - if a
        task is active, we will continue polling in the background and update
        the current task view accordingly - when there is no active task (i.e.
        the server is currently idle) we will stop the background polling and
        only request updates upon user actions, but not when the user is idle
        (i.e. does not click around in the UI)

        Setting poll-when-idle to "yes" will do background polling even when
        there are no current tasks; this may be useful if you defined multiple
        users and want to see the tasks the other user is queuing on the server
        while you are actually idle.

        The tasks that are monitored are:

          - adding files or directories

          - removing items or containers

          - automatic rescans

    Child tags:

      o <accounts enabled="yes" session-timeout="30"/>

        Optional

        This section holds various account settings.

        Attributes:

          - enabled=...

            Optional

            Default: yes

            Specifies if accounts are enabled ("yes") or disabled ("no").

          - session-timeout=...

            Optional

            Default: 30

            The session-timeout attribute specifies the timeout interval in
            minutes. The server checks every five minutes for sessions that
            have timed out, therefore in the worst case the session times out
            after session-timeout + 5 minutes.

        Accounts can be defined as shown below:

          - <account user="name" password="password"/>
            <account user="name" password="password"/>
            ....

            Optional

            There can be multiple users, however this is mainly a feature for
            the future. Right now there are no per-user permissions.

      o <items-per-page default="25">

        Optional

        Default: 25

        This sets the default number of items per page that will be shown when
        browsing the database in the web UI.

        The values for the items per page drop down menu can be defined in the
        following manner:

          - <option>10</option>
            <option>25</option>
            <option>50</option>
            <option>100</option>

            Default: 10, 25, 50, 100

            Note:

                this list must contain the default value, i.e. if you define a
                default value of 25, then one of the <option> tags must also
                list this value.

  * <storage caching="yes">

    Required

    Defines the storage section - database selection is done here. Currently
    sqlite3 and mysql are supported. Each storage driver has it's own
    configuration parameters.

      o caching="yes"

        Optional

        Default: yes

        Enables caching, this feature should improve the overall import speed.

      o <sqlite enabled="yes>

        Required if MySQL is not defined

        Allowed values are "sqlite3" or "mysql", the available options depend
        on the selected driver.

          - enabled="yes"

            Optional

            Default: yes

        Below are the sqlite driver options:

          - <database-file>mediatomb.db</database-file>

            Optional

            Default: mediatomb.db

            The database location is relative to the server's home, if the
            sqlite database does not exist it will be created automatically.

          - <synchronous>off</synchronous>

            Optional

            Default: off

            Possible values are "off", "normal" and "full".

            This option sets the SQLite pragma "synchronous". This setting will
            affect the performance of the database write operations. For more
            information about this option see the SQLite documentation: http://
            www.sqlite.org/pragma.html#pragma_synchronous

          - <on-error>restore</on-error>

            Optional

            Default: restore

            Possible values are "restore" and "fail".

            This option tells MediaTomb what to do if an SQLite error occurs
            (no database or a corrupt database). If it is set to "restore" it
            will try to restore the database from a backup file (if one exists)
            or try to recreate a new database from scratch.

            If the option is set to "fail", MediaTomb will abort on an SQLite
            error.

          - <backup enabled="no" interval="6000"/>

            Optional

            Backup parameters:

              * enabled=...

                Optional

                Default: no

                Enables or disables database backup.

              * interval=...

                Optional

                Default: 600

                Defines the backup interval in seconds.

      o <mysql enabled="no"/>

        Defines the MySQL storage driver section.

          - enabled=...

            Optional

            Default: yes

            Enables or disables the MySQL driver.

        Below are the child tags for MySQL:

          - <host>localhost</host>

            Optional

            Default: "localhost"

            This specifies the host where your MySQL database is running.

          - <port>0</port>

            Optional

            Default: 0

            This specifies the port where your MySQL database is running.

          - <username>root</username>

            Optional

            Default: "mediatomb"

            This option sets the user name that will be used to connect to the
            database.

          - <password></password>

            Optional

            Default: no password

            Defines the password for the MySQL user. If the tag doesn't exist
            MediaTomb will use no password, if the tag exists, but is empty
            MediaTomb will use an empty password. MySQL has a distinction
            between no password and an empty password.

          - <database>mediatomb</database>

            Optional

            Default: "mediatomb"

            Name of the database that will be used by MediaTomb.

6.1.1. Extended Runtime Options

<extended-runtime-options>

These options reside under the server tag and allow to additinally control the
so called "runtime options". The difference to the import options is:

Import options are only triggered when data is being imported into the
database, this means that if you want new settings to be applied to already
imported data, you will have to reimport it. Runtime options can be switched on
and off without the need to reimport any media. Unfortunately you still need to
restart the server so that these options take effect, however after that they
are immediately active.

  * <ffmpegthumbnailer enabled="no">

    Optional

    Default: no

    Ffmpegthumbnailer is a nice, easy to use library that allows to generate
    thumbnails from video files. Some DLNA compliant devices support video
    thumbnails, if you think that your device may be one of those you can try
    enabling this option. It would also make sense to enable the protocolInfo
    option, since it will add specific DLNA tags to tell your device that a
    video thumbnail is being offered by the server.

    Note:

        thumbnails are not cached and not stored anywhere, they will be
        generated on the fly in memory and released afterwards. If your device
        supports video thumbnails and requests them from the server in large
        amounts, the performance when browsing video containers will depend on
        the speed of your machine. A feature to allow caching of thumbnails is
        planned for future releases.

    The following options allow to control the ffmpegthumbnailer library (these
    are basically the same options as the ones offered by the ffmpegthumbnailer
    command line application). All tags below are optional and have sane
    default values.

      o <thumbnail-size>128</thumbnail-size>

        Optional

        Default: 128

        The thumbnail size should not exceed 160x160 pixels, higher values can
        be used but will mostprobably not be supported by DLNA devices. The
        value of zero or less is not allowed.

      o <seek-percentage>5</seek-percentage>

        Optional

        Default: 5

        Time to seek to in the movie (percentage), values less than zero are
        not allowed.

      o <filmstrip-overlay>yes</filmstrip-overlay>

        Optional

        Default: yes

        Creates a filmstrip like border around the image, turn this option off
        if you want pure images.

      o <workaround-bugs>no</workaround-bugs>

        Optional

        Default: no

        Accodring to ffmpegthumbnailer documentation, this option will enable
        workarounds for bugs in older ffmpeg versions. You can try enabling it
        if you experience unexpected behaviour, like hangups during thumbnail
        generation, crashes and alike.

  * <mark-played-items enabled="no" suppress-cds-updates="yes">

    Optional

    The attributes of the tag have the following meaning:

      o enabled=...

        Optional

        Default: no

        Enables or disables the marking of played items, seto to "yes" to
        enable the feature.

      o suppress-cds-updates=...

        Optional

        Default: yes

        This is an advanced feature, leave the default setting if unsure.
        Usually, when items are modified we send out container updates as
        specified in the Content Directory Service. This notifies the player
        that data in a particular container has changed, players that support
        CDS updates will rebrowse the container and refresh the view. However,
        in this case we probably do not want it (this actually depends on the
        particular player implementation). For example, if we update the list
        of currently playing items, the player could interrupt playback and
        rebrowse the current container - clearly an unwatned behaviour. Because
        of this, we provide an option to suppress and not send out container
        updates - only for the case where the item is marked as "played". In
        order to see the changes you will have to get out of the current
        container and enter it again - then the view on your player should get
        updated.

        Note:

            some players (i.e. PS3) cache a lot of data and do not react to
            container updates, for those players it may be necessary to leave
            the server view or restart the player in order to update content
            (same as when adding new data).

    The following tag defines how played items should be marked:

      o <string mode="prepend">* </string>

        Optional

        Default: *

        Specifies what string should be appended or prepended to the title of
        the object that will be marked as "played".

          - mode=...

            Optional

            Default: prepend

            Specifies how a string should be added to the object's title,
            allowed values are "append" and "prepend".

6.2. Import Settings

The import settings define various options on how to aggregate the content.

<import hidden-files="no">

Optional

This tag defines the import section.

Attributes:

  * hidden-files=...

    Optional

    Default: no

    This attribute defines if files starting with a dot will be imported into
    the database ("yes"). Autoscan can override this attribute on a per
    directory basis.

Child tags:

  * <filesystem-charset>ISO-8859-1</filesystem-charset>

    Optional

    Default: if nl_langinfo() function is present, this setting will be auto
    detected based on your system locale, else set to ISO-8859-1

    Defines the charset of the filesystem. For example, if you have file names
    in Cyrillic KOI8-R encoding, then you should specify that here. The server
    uses UTF-8 internally, this import parameter will help you to correctly
    import your data.

  * <metadata-charset>ISO-8859-1</metadata-charset>

    Optional

    Default: if nl_langinfo() function is present, this setting will be auto
    detected based on your system locale, else set to ISO-8859-1

    Same as above, but defines the charset of the metadata (i.e. id3 tags, Exif
    information, etc.)

  * <scripting script-charset="UTF-8">

    Optional

    Defines the scripting section.

      o script-charset=...

        Optional

        Default: UTF-8

    Below are the available scripting options:

      o <virtual-layout type="builtin">

        Optional

        Defines options for the virtual container layout; the so called
        "virtual container layout" is the way how the server organizes the
        media according to the extracted metadata. For example, it allows
        sorting audio files by Album, Artist, Year and so on.

          - type=...

            Optional

            Default: builtin

            Specifies what will be used to create the virtual layout, possible
            values are:

              * builtin: a default layout will be created by the server

              * js: a user customizable javascript will be used (MediaTomb must
                be compiled with js support)

              * disabled: only PC-Directory structure will be created, i.e. no
                virtual layout

        The virtual layout can be adjusted using an import script which is
        defined as follows:

          - <import-script>/path/to/my/import-script.js</import-script>

            Required if virtual layout type is "js"

            Default: ${prefix}/share/mediatomb/js/import.js, where ${prefix} is
            your installation prefix directory.

            Points to the script invoked upon media import. For more details
            read doc/scripting.txt

          - <dvd-script>/path/to/my/import-dvd.js</dvd-script>

            Optional, only has effect when layout type is "js" and if MediaTomb
            was compiled with libdvdread support.

            Default: ${prefix}/share/mediatomb/js/import-dvd.js, where $
            {prefix} is your installation prefix directory.

            Points to the script invoked upon import of DVD iso images. For
            more details read doc/scripting.txt

      o <common-script>/path/to/my/common-script.js</common-script>

        Optional

        Default: ${prefix}/share/mediatomb/js/common.js, where ${prefix} is
        your installation prefix directory.

        Points to the so called common script - think of it as a custom library
        of js helper functions, functions added there can be used in your
        import and in your playlist scripts. For more details read doc/
        scripting.txt

      o <playlist-script create-link="yes">/path/to/my/playlist-script.js</playlist-script>

        Optional

        Default: ${prefix}/share/mediatomb/js/playlists.js, where ${prefix} is
        your installation prefix directory.

        Points to the script that is parsing various playlists, by default
        parsing of pls and m3u playlists is implemented, however the script can
        be adapted to parse almost any kind of text based playlist. For more
        details read doc/scripting.txt

          - create-link=...

            Optional

            Default: yes

            Links the playlist to the virtual container which contains the
            expanded playlist items. This means, that if the actual playlist
            file is removed from the database, the virtual container
            corresponding to the playlist will also be removed.

  * <magic-file>/path/to/my/magic-file</magic-file>

    Optional

    Default: System default

    Specifies an alternative file for filemagic, containing mime type
    information.

  * <autoscan use-inotify="auto">

    Optional

    Specifies a list of default autoscan directories.

    This section defines persistent autoscan directories. It is also possible
    to define autoscan directories in the UI, the difference is that autoscan
    directories that are defined via the config file can not be removed in the
    UI. Even if the directory gets removed on disk, the server will try to
    monitor the specified location and will re add the removed directory if it
    becomes available/gets created again.

      o use-inotify=...

        Optional

        Default: auto

        Specifies if the inotify autoscan feature should be enabled. The
        default value is "auto", which means that availability of inotify
        support on the system will be detected automatically, it will then be
        used if available. Setting the option to 'no' will disable inotify even
        if it is available. Allowed values: "yes", "no", "auto"

    Child tags:

      o <directory location="/media" mode="timed" interval="3600"
            level="full" recursive="no" hidden-files="no"/>
        <directory location="/audio" mode="inotify"
            recursive="yes" hidden-files="no"/>
        ...

        Optional

        Defines an autoscan directory and it's parameters.

        The attributes specify various autoscan options:

          - location=...

            Required

            Absolute path to the directory that shall be monitored.

          - mode=...

            Required

            Scan mode, currently "inotify" and "timed" are supported. Timed
            mode rescans the given directory in specified intervals, inotify
            mode uses the kernel inotify mechanism to watch for filesystem
            events.

          - interval=...

            Required for "timed" mode

            Scan interval in seconds.

          - level=...

            Required for "timed" mode

            Either "full" or "basic". Basic mode will only check if any files
            have been added or were deleted from the monitored directory, full
            mode will remember the last modification time and re add the media
            that has changed. Full mode might be useful when you want to
            monitor changes in the media, like id3 tags and alike.

          - recursive=...

            Required

            Values of "yes" or "no" are allowed, specifies if autoscan shall
            monitor the given directory including all sub directories.

          - hidden-files=...

            Optional

            Default: value specified in <import hidden-files=""/>

            Allowed values: "yes" or "no", process hidden files, overrides the
            hidden-files value in the <import/> tag.

  * <mappings>

    Optional

    Defines various mapping options for importing media, currently two
    subsections are supported.

    This section defines mime type and upnp:class mappings, it is vital if
    filemagic is not available - in this case media type auto detection will
    fail and you will have to set the mime types manually by matching the file
    extension. It is also helpful if you want to override auto detected mime
    types or simply skip filemagic processing for known file types.

      o <extension-mimetype ignore-unknown="no" case-sensitive="no">

        Optional

        This section holds the file name extension to mime type mappings.

        Attributes:

          - ignore-unknown=...

            Optional

            Default: no

            If ignore-unknown is set to "yes", then only the extensions that
            are listed in this section are imported.

          - case-sensitive=...

            Optional

            Default: no

            Specifies if extensions listed in this section are case sensitive,
            allowed values are "yes" or "no".

        Child tags:

          - <map from="mp3" to="audio/mpeg"/>

            Optional

            Specifies a mapping from a certain file name extension (everything
            after the last dot ".") to mime type.

            Note:

                this improves the import speed, because invoking libmagic to
                discover the right mime type of a file is omitted for files
                with extensions listed here.

            Note:

                extension is case sensitive, this will probably need to be
                fixed.

      o <mimetype-upnpclass>

        Optional

        This section holds the mime type to upnp:class mappings.

        Child tags:

          - <map from="audio/*" to="object.item.audioItem.musicTrack"/>

            Optional

            Specifies a mapping from a certain mime type to upnp:class in the
            Content Directory. The mime type can either be entered explicitly
            "audio/mpeg" or using a wildcard after the slash "audio/*". The
            values of "from" and "to" attributes are case sensitive.

      o <mimetype-contenttype>

        Optional

        This section makes sure that the server knows about remapped mimetypes
        and still extracts the metadata correctly. For example, we know that
        id3lib can only handle mp3 files, the default mimetype of mp3 content
        is audio/mpeg. If the user remaps mp3 files to a different mimetype, we
        must know about it so we can still pass this item to id3lib for
        metadata extraction.

        Note:

            if this section is not present in your config file, the defaults
            will be filled in automatically. However, if you add an empty tag,
            without defining the following <treat> tags, the server will assume
            that you want to have an empty list and no files will be process by
            the metadata handler.

          - <treat mimetype="audio/mpeg" as="mp3"/>

            Optional

            Tells the server what content the specified mimetype actually is.

            Note:

                it makes no sense to define 'as' values that are not below, the
                server only needs to know the content type of the ones
                specified, otherwise it does not matter.

            The 'as' attribute can have following values:

              * mp3

                Default mimetype: audio/mpeg

                The content is an mp3 file and should be processed by either
                id3lib or taglib (if available).

              * ogg

                Default mimetype: application/ogg

                The content is an ogg file and should be processed by taglib
                (if available).

              * flac

                Default mimetype: audio/x-flac

                The content is a flac file and should be processed by taglib
                (if available).

              * jpg

                Default mimetype: image/jpeg

                The content is a jpeg image and should be processed by libexif
                (if available).

              * playlist

                Default mimetype: audio/x-mpegurl or audio/x-scpls

                The content is a playlist and should be processed by the
                playlist parser script.

              * pcm

                Default mimetype: audio/L16 or audio/x-wav

                The content is a PCM file.

              * avi

                Default mimetype: video/x-msvideo

                The content is an AVI container, FourCC extraction will be
                attempted.

  * <library-options>

    Optional

    This section holds options for the various supported import libraries, it
    is useful in conjunction with virtual container scripting, but also allows
    to tune some other features as well.

    Currently the library-options allow additional extraction of the so called
    auxilary data (explained below) and provide control over the video
    thumbnail generation.

    Here is some information on the auxdata: UPnP defines certain tags to pass
    along metadata of the media (like title, artist, year, etc.), however some
    media provides more metadata and exceeds the scope of UPnP. This additional
    metadata can be used to fine tune the server layout, it allows the user to
    create a more complex container structure using a customized import script.
    The metadata that can be extracted depends on the library, currently we
    support libebexif and libextractor, the libraries provide a default set of
    keys that can be passed in the options below. The data according to those
    keys will the be extracted from the media and imported into the database
    along with the item. When processing the item, the import script will have
    full access to the gathered metadata, thus allowing the user to organize
    the data with the use of the extracted information. A practical example
    would be: if have more than one digital camera in your family you could
    extract the camera model from the Exif tags and sort your photos in a
    structure of your choice, like:

    Photos/MyCamera1/All Photos

    Photos/MyCamera1/Date

    Photos/MyCamera2/All Photos

    Photos/MyCamera2/Date

    etc.

    Child tags:

      o <libexif>

        Optional

        Options for the exif library.

        Child tags:

          - <auxdata>

            Optional

            Currently only adding keywords to auxdata is supported. For a list
            of keywords/tags see the libexif documentation. Auxdata can be read
            by the import java script to gain more control over the media
            structure.

            Child tags:

              * <add-data tag="keyword1"/>
                <add-data tag="keyword2"/>
                ...

                Optional

                If the library was able to extract the data according to the
                given keyword, it will be added to auxdata. You can then use
                that data in your import scripts.

        A sample configuration for the example described above would be:

        <libexif>
            <auxdata>
                <add-data tag="EXIF_TAG_MODEL"/>
            </auxdata>
        </libexif>

      o <id3>

        Optional

        These options apply to id3lib or taglib libraries.

        Child tags:

          - <auxdata>

            Optional

            Currently only adding keywords to auxdata is supported. The
            keywords are those defined in the id3 specification, we do not
            perform any extra checking, so you could try to use any string as a
            keyword - if it does not exist in the tag nothing bad will happen.

            Here is a list of possible keywords:

            TALB, TBPM, TCOM, TCON, TCOP, TDAT, TDLY, TENC, TEXT, TFLT, TIME,
            TIT1, TIT2, TIT3, TKEY, TLAN, TLEN, TMED, TOAL, TOFN, TOLY, TOPE,
            TORY, TOWN, TPE1, TPE2, TPE3, TPE4, TPOS, TPUB, TRCK, TRDA, TRSN,
            TRSO, TSIZ, TSRC, TSSE, TYER, TXXX

            Child tags:

              * <add-data tag="TCOM"/>
                <add-data tag="TENC"/>
                ...

                Optional

                If the library was able to extract the data according to the
                given keyword, it will be added to auxdata. You can then use
                that data in your import scripts.

        A sample configuration for the example described above would be:

        <id3>
            <auxdata>
                <add-data tag="TENC"/>
            </auxdata>
        </id3>

      o <libextractor>

        Optional

        Options for the extractor library.

        Child tags:

          - <auxdata>

            Optional

            Currently only adding keywords to auxdata is supported. For a list
            of keywords/tags see the libextractor documentation.

            Child tags:

              * <add-data tag="keyword1"/>
                <add-data tag="keyword2"/>
                ...

                Optional

                If the library was able to extract the data according to the
                given keyword, it will be added to auxdata. You can then use
                that data in your import scripts.

6.2.1. Online Content Settings

This section resides under import and defines options for various supported
online services.

<online-content fetch-buffer-size="262144" fetch-buffer-fill-size="0">

Optional

This tag defines the online content section.

Attributes:

  * fetch-buffer-size=...

    Optional

    Default: 262144

    Often, online content can be directly accessed by the player - we will just
    give it the URL. However, sometimes it may be necessary to proxy the
    content through MediaTomb. This setting defines the buffer size in bytes,
    that will be used when fetching content from the web. The value must not be
    less than allowed by the curl library (usually 16384 bytes).

  * fetch-buffer-fill-size=...

    Optional

    Default: 0 (disabled)

    This setting allows to prebuffer a certain amount of data, given in bytes,
    before sending it to the player, this should ensure a constant data flow in
    case of slow connections. Usually this setting is not needed, because most
    players will anyway have some kind of buffering, however if the connection
    is particularly slow you may want to try enable this setting.

Below are the settings for supported services.

6.2.2. YouTube Service

MediaTomb allows you to watch YouTube videos using your UPnP device, you can
specify what content you are interested in, we will import the meta data and
present it in the database, so you can browse the content on your player just
like you do it with your local data.

WANING:

    by using this feature you may be violating the YouTube service terms and
    conditions: http://www.youtube.com/t/terms

Note:

    we do not download/mirror the actual videos, we only get description of the
    content and present it in the database. The actual video is only streamed
    when you press play on your device. So, when we use the term "retrieve
    videos" we actually mean retrieving the video name, description and
    associated meta data, not the actual flv file.

Note:

    so far we have not yet seen many devices that will natively support the
    .flv format, you will need to setup appropriate transcoding profiles to
    make use of the YouTube feature.

<YouTube enabled="no" refresh="12600" update-at-start="yes" purge-after="1200000" racy-content="exclude">

Optional

Options and setting for YouTube service support, the attributes are:

  * enabled=...

    Optional

    Default: no

    Enables or disables the service, allowed values are "yes" or "no".

  * refresh=...

    Optional

    Default: 28800

    Refresh interval in seconds, each time the interval elapses we will contact
    the YouTube server and fetch new meta data, presenting the changes in the
    database view. This allows you to stay up to date with what is available on
    YouTube, you probably should not need to update more than once per day, so
    specify a reasonably high value here. Setting the option to 0 (zero)
    disables automatic refreshing.

  * purge-after=...

    Optional

    Default: 0 (disabled)

    Time amount in seconds when data that has not been updated is considered
    old and can be purged from the database. This setting helps to prevent an
    endless filling of the database with YouTube meta data, the idea is the
    following: each video has a unique ID, during a refresh cycle the video
    meta data will be imported into the database and a time stamp will be
    added. Each refresh cycle we may encounter same content (i.e. nothing
    changed on the YouTube site), we will update the time stamp. However, if a
    particular video is no longer available on YouTube it will not be
    refreshed, once the time stamp exceeds the purge-after value we will remove
    the meta data for this particular video from the database.

  * update-at-start=...

    Optional

    Default: no

    This option defines if we will contact the service right after MediaTomb
    was started (about 10 seconds after start up) or if data should be fetched
    when the first refresh cycle kicks in. It may be useful if you frequently
    restart the server and do not want the content to be updated each time.
    Allowed values are "yes" or "no".

  * racy-content=...

    Optional

    Default: exclude

    Specifies if restricted content should be inclueded in the search results.
    The option will automatically be used with YouTube requests that support.
    By default restricted content is not included.

Below are various options that allow you to define what content you are
interested in.

6.2.3. Weborama Service

MediaTomb allows you to access Weborama content and to play it on your device.

Note:

    we do not download/mirror the actual audio files, we only get description
    of the content and present it in the database. The actual media is only
    streamed when you press play on your device. So, when we use the term
    "retrieve media" we actually mean retrieving the song name, description and
    associated meta data, not the actual audio file.

<Weborama enabled="no" refresh="12600" update-at-start="no">

Optional

Options and settings for Weborama service support:

  * enabled=...

    Optional

    Default: no

    Enables or disables the service, allowed values are "yes" or "no".

  * refresh=...

    Optional

    Default: 28800

    Refresh interval in seconds, each time the interval elapses we will contact
    the Weborama server and fetch new meta data, presenting the changes in the
    database view. This allows you to get new playlists and update the content
    that you want to play from Weborama. Setting the option to 0 (zero)
    disables automatic refreshing.

  * update-at-start=...

    Optional

    Default: no

    This option defines if we will contact the service right after MediaTomb
    was started (about 10 seconds after start up) or if data should be fetched
    when the first refresh cycle kicks in. It may be useful if you frequently
    restart the server and do not want the content to be updated each time.
    Allowed values are "yes" or "no".

The request for fetching particular content is described using the following
tag:

<playlist name="Dark" mood="dark" amount="5">

The attributes have the following meaning:

  * name=...

    Required

    Name of the request, this name will be used in the virtual layout when
    presenting the content.

  * mood=...

    Optional

    Defines the mood of the user, the returned content is filtered accordingly.
    Possible values are:

      o calm-positive

      o positive

      o energetic-positive

      o calm

      o neutral

      o energetic

      o calm-dark

      o dark

      o energetic-dark

  * amount=...

    Optional

    Default: 200

    Integer value, defining the number of songs that should be fetched for this
    request.

  * <type id="0">playlist</type>

    Optional

    Type of the generated content.

      o id=

        Optional

        Default: 0

        The value of the id parameter is tightly coupled to the type parameter
        which is described above.

          - <type id="0">playlist</type>

            Id value of zero generates a random playlist.

          - <type id="playlist id">playlist</type>

            Requests a playlist wich is identified by the playlist id which is
            passed via the id parameter.

          - <type id="song hash">audio</type>

            Requests a particular song which is identified by the hash which is
            passed via the id parameter.

          - <type id="album id">album</type>

            Requests a particular album which is identified by the album id
            which is passed via the id parameter.

    The allowed type values are:

      o audio

        The request delivers only one song, identified by the id parameter.

      o playlist

        The request delivers a users playlist, identified by the id parameter.
        If id is zero, then the request delivers content which is specified
        using the mood and filter parameters.

      o album

        The request delivers songs from a particular album, identified by the
        id parameter.

  * <filter>

    Optional

    Allows to filter the returned content, this is especially useful when
    generating random playlists. Allowed subtags are:

      o <genres>genre1,genre2,genre3</genres>

        Optional

        Allows to filter by one or more genres, multiple genres are separated
        by a comma. The list of supported genres is:

          - favorite

          - friends

          - uploaded

          - used_last

6.2.4. Apple Trailers Service

MediaTomb allows you to access Apple trailers content, depending on your device
you may also need to enable transcoding - the trailers are provided as h264 in
a quicktime container.

Note:

    we do not download/mirror the actual video files, we only get description
    of the content and present it in the database. The actual media is only
    streamed when you press play on your device. So, when we use the term
    "retrieve media" we actually mean retrieving the media name, description
    and associated meta data, not the actual file.

<AppleTrailers enabled="no" refresh="43200" update-at-start="no">

Optional

Options and settings for Apple Trailers support:

  * enabled=...

    Optional

    Default: no

    Enables or disables the service, allowed values are "yes" or "no".

  * refresh=...

    Optional

    Default: 43200 (every 12 hours)

    Refresh interval in seconds, each time the interval elapses we will contact
    the Apple trailers server and fetch new meta data, presenting the changes
    in the database view. This allows you to update the content that you want
    to play from this service. Setting the option to 0 (zero) disables
    automatic refreshing.

  * update-at-start=...

    Optional

    Default: no

    This option defines if we will contact the service right after MediaTomb
    was started (about 10 seconds after start up) or if data should be fetched
    when the first refresh cycle kicks in. It may be useful if you frequently
    restart the server and do not want the content to be updated each time.
    Allowed values are "yes" or "no".

6.3. Transcoding Settings

The transcoding section allows to define ways on how to transcode content.

<transcoding enabled="yes" fetch-buffer-size="262144" fetch-buffer-fill-size="0">

Optional

This tag defines the transcoding section.

Attributes:

  * enabled=...

    Optional

    Default: yes

    This attribute defines if transcoding is enabled as a whole, possible
    values are "yes" or "no".

  * fetch-buffer-size=...

    Optional

    Default: 262144

    In case you have transcoders that can not handle online content directly
    (see the accept-url parameter below), it is possible to put the transcoder
    between two FIFOs, in this case MediaTomb will fetch the online content.
    This setting defines the buffer size in bytes, that will be used when
    fetching content from the web. The value must not be less than allowed by
    the curl library (usually 16384 bytes).

  * fetch-buffer-fill-size=...

    Optional

    Default: 0 (disabled)

    This setting allows to prebuffer a certain amount of data before sending it
    to the transcoder, this should ensure a constant data flow in case of slow
    connections. Usually this setting is not needed, because most transcoders
    will just patiently wait for data and we anyway buffer on the output end.
    However, we observed that ffmpeg will fail to transcode flv files if it
    encounters buffer underruns - this setting helps to avoid this situation.

Child tags:

  * <mimetype-profile-mappings>

    The mime type to profile mappings define which mime type is handled by
    which profile.

    Different mime types can map to the same profile in case that the
    transcoder in use supports various input formats. The same mime type can
    also map to several profiles, in this case multiple resources in the XML
    will be generated, allowing the player to decide which one to take.

    The mappings under mimetype-profile are defined in the following manner:

      o <transcode mimetype="audio/x-flac" using="oggflac-pcm"/>

        Optional

        In this example we want to transcode our flac audio files (they have
        the mimetype audio/x-flac) using the "oggflac-pcm" profile which is
        defined below.

          - mimetype=...

            Selects the mime type of the source media that should be
            transcoded.

          - using=...

            Selects the transcoding profile that will handle the mime type
            above. Information on how to define transcoding profiles can be
            found below.

  * <profiles>

    This section defines the various transcoding profiles.

      o <profile name="oggflag-pcm" enabled="yes" type="external">

        Optional

        Definition of a transcoding profile.

          - name=...

            Required

            Name of the transcoding profile, this is the name that is specified
            in the mime type to profile mappings.

          - enabled=...

            Required

            Enables or disables the profile, allowed values are "yes" or "no".

          - type=...

            Required

            Defines the profile type, currently only "external" is supported,
            this will change in the future.

              * <mimetype>audio/x-wav</mimetype>

                Required

                Defines the mime type of the transcoding result (i.e. of the
                transcoded stream). In the above example we transcode to PCM.

              * <accept-url>yes</accept-url>

                Optional

                Default: yes

                Some transcoders are able to handle non local content, i.e.
                instead giving a local file name you can pass an URL to the
                transcoder. However, some transcoders can only deal with local
                files, for this case set the value to "no".

              * <first-resource>no</first-resource>

                Optional

                Default: no

                It is possible to offer more than one resource in the browse
                result, a good player implementation will go through all
                resources and pick the one that it can handle best.
                Unfortunately most players only look at the first resource and
                ignore the rest. When you add a transcoding profile for a
                particular media type it will show up as an additional resource
                in the browse result, using this parameter you can make sure
                that the transcoded resource appears first in the list.

                Note:

                    if more than one transcoding profile is applied on one
                    source media type (i.e. you transcode an OGG file to MP3
                    and to PCM), and the first-resource parameter is specified
                    in both profiles, then the resource positions are
                    undefined.

              * <hide-original-resource>no</hide-original-resource>

                Optional

                Default: no

                This parameter will hide the resource of the original media
                when sending the browse result to the player, this can be
                useful if your device gets confused by multiple resources and
                allows you to send only the transcoded one.

              * <accept-ogg-theora>no</accept-org-theora>

                Optional

                Default: no

                As you may know, OGG is just a container, the content could be
                Vorbis or Theora while the mime type is "application/ogg". For
                transcoding we need to identify if we are dealing with audio or
                video content, specifying yes in this tag in the profile will
                make sure that only OGG files containing Theora will be
                processed.

              * <dvd-only>no<dvd-only>

                Optional

                Default: no

                This is a special option which is related to DVD image support
                that is offered via libdvdnav. We encountered a problem that
                some devices fail to play the stream that we get from
                libdvdnav, for those devices remuxing to TS may be required.

                This option allows to setup a transcoding profile that will
                only transcode streams coming from the DVD image. The option is
                needed to prevent transcoding of normal mpeg streams, without
                it those streams would also get transcoded because the settings
                are based on the mime type.

              * <avi-fourcc-list mode="ignore">

                Optional

                Default: disabled

                This option allows to specify a particular list of AVI fourcc
                strings that can be either set to be ignored or processed by
                the profile.

                Note:

                    this option has no effect on non AVI content.

                  o mode=...

                    Required

                    Specifies how the list should be handled by the transcoding
                    engine, possible values are:

                      - "disabled"

                        The option is completely disabled, fourcc list is not
                        being processed.

                      - "process"

                        Only the fourcc strings that are listed will be
                        processed by the transcoding profile, AVI files with
                        other fourcc strings will be ignored. Setting this is
                        useful if you want to transcode only some specific
                        fourcc's and not transcode the rest.

                      - "ignore"

                        The fourcc strings listed will not be transcoded, all
                        other codecs will be transcoded. Setting this might be
                        useful if you want to prevent a limited number of
                        codecs from being transcoded, but want to apply
                        transcoding on the rest (i.e. - do not transcode divx
                        and xvid, but want to transcode mjpg and whatever else
                        might be in the AVI container).

                The list of fourcc strings is enclosed in the avi-fourcc-list
                section:

                  o <fourcc>XVID</fourcc>
                    <fourcc>DX50</fourcc>

                    etc...

              * <agent command="ogg123" arguments="-d wav -f %out %in/>

                Required

                Defines the transcoding agent and the parameters, in the
                example above we use ogg123 to convert ogg or flac to wav.

                  o command=...

                    Required

                    Defines the transcoder binary that will be executed by
                    MediaTomb upon a transcode request, the binary must be in
                    $PATH. It is very important that the transcoder is capable
                    of writing the output to a FIFO, some applications, for
                    example ffmpeg, have problems with that. The command line
                    arguments are specified separately (see below).

                  o arguments=...

                    Required

                    Specifies the command line arguments that will be given to
                    the transcoder application upon execution. There are two
                    special tokens:

                    %in
                    %out

                    Those tokens get substituted by the input file name and the
                    output FIFO name before execution.

              * <buffer size="1048576" chunk-size="131072" fill-size="262144"/>

                Required

                These settings help you to achieve a smooth playback of
                transcoded media. The actual values need to be tuned and depend
                on the speed of your system. The general idea is to buffer the
                data before sending it out to the player, it is also possible
                to delay first playback until the buffer is filled to a certain
                amount. The prefill should give you enough space to overcome
                some high bitrate scenes in case your system can not transcode
                them in real time.

                  o size=...

                    Required

                    Size of the buffer in bytes.

                  o chunk-size=...

                    Required

                    Size of chunks in bytes, that are read by the buffer from
                    the transcoder. Smaller chunks will produce a more constant
                    buffer fill ratio, however too small chunks may slow things
                    down.

                  o fill-size=...

                    Required

                    Initial fill size - number of bytes that have to be in the
                    buffer before the first read (i.e. before sending the data
                    to the player for the first time). Set this to 0 (zero) if
                    you want to disable prefilling.

              * <resolution>320x240</resolution>

                Optional

                Default: not specified

                Allows you to tell the resolution of the transcoded media to
                your player. This may be helpful if you want to generate
                thumbnails for your photos, or if your player has the ability
                to pick video streams in a particular resolution. Of course the
                setting should match the real resolution of the transcoded
                media.

              * <use-chunked-encoding>yes</use-chunked-encoding>

                Optional

                Default: yes

                Specifies that the content should be sent out using chunked
                HTTP encoding, this is the default setting for transcoded
                streams, because the content length of the data is not known.

              * <sample-frequency>source</sample-frequency>

                Optional

                Default: source

                Specifies the sample frequency of the transcoded media, this
                information is passed to the player and is particularly
                important when streaming PCM data. Possible values are: source 
                (automatically set the same frequency as the frequency of the
                source content, which is useful if you are not doing any
                resampling), off (do not provide this information to the
                player), frequency (specify a fixed value, where frequency is a
                numeric value > 0)

              * <audio-channels>source</audio-channels>

                Optional

                Default: source

                Specifies the number of audio channels in the transcoded media,
                this information is passed to the player and is particularly
                important when streaming PCM data. Possible values are: source 
                (automatically set the same number of audio channels as in the
                source content), off (do not provide this information to the
                player), number (specify a fixed value, where number is a
                numeric value > 0)

              * <thumbnail>yes</thumbnail>

                Optional

                Default: no

                Note:

                    this is an experimental option, the implementation will be
                    refined in the future releases.

                This is a special option which was added for the PS3 users. If
                the resolution option (see above) was set, then, depending on
                the resolution an special DLNA tag will be added, marking the
                resource as a thumbnail. This is useful if you have a
                transcoding script that extracts an image out of the video and
                presents it as a thumbnail.

                Use the option with caution, no extra checking is being done if
                the resulting mimetype represents an image, also, it is will
                only work if the output of the profile is a JPG image.

7. Supported Devices

Attention Hardware Manufacturers:

If you want to improve compatibility between MediaTomb and your renderer device
or if you are interested in a port of MediaTomb for your NAS device please
e-mail to: <contact at mediatomb dot cc>

7.1. MediaRenderers

MediaTomb supports all UPnP compliant MediaRenderers, however there can always
be various problems that depend on the particular device implementation. We
always try to implement workarounds to compensate for failures and limitations
of various renderers.

This is the list of client devices that MediaTomb has been tested with and that
are known to work. Please drop us a mail if you are using MediaTomb with a
device that is not in the list, report any success and failure. We will try to
fix the issues and will add the device to the list.

7.1.1. Acer

  * AT3705-MGW

7.1.2. Conceptronic

  * C54WMP

7.1.3. Denon

  * AVR 4306

7.1.4. D-Link

  * DSM-320

  * DSM-320RD

  * DSM-510

  * DSM-520

Some additional settings in MediaTomb configuration are required to enable
special features for the DSM renderers. If you have a DSM-320 and are
experiencing problems during AVI playback, add the following to the server
section of your config.xml:

<custom-http-headers>
    <add header="X-User-Agent: redsonic"/>
</custom-http-headers>

Further, the DSM-320 behaves differently if it thinks that it is dealing with
the D-Link server. Add the following to the server section of your
configuration to enable srt subtitle support:

<manufacturerURL>redsonic.com</manufacturerURL>
<modelNumber>105</modelNumber>

It is still being investigated, but we were able to get subtitles working with
a U.S. DSM-320 unit running firmware version 1.09

Also, the DSM-510 (probably also valid for other models) will only play avi
files if the mimetype is set to video/avi, you may want to add a mapping for
that to the extension-mimetype section in your config.xml:

<map from="avi" to="video/avi"/>

7.1.5. Freecom

  * MusicPal

7.1.6. Haeger

  * OnAir (also known as BT Internet Radio)

7.1.7. HP

  * MediaSmart TV

Users reported that after a firmwre upgrade the device stopped working
properly. It seems that it does not sue the UPnP Browse action anymore, but now
uses the optional Search action which is not implemented in MediaTomb.

7.1.8. I-O Data

  * AVeL LinkPlayer2 AVLP2/DVDLA

7.1.9. Linksys

  * WMLS11B (Wireless-B Music System)

  * KiSS 1600

7.1.10. NeoDigits

  * HELIOS X3000

7.1.11. Netgear

  * EVA700

7.1.12. Philips

  * Streamium SL-300i

  * Streamium SL-400i

  * Streamium MX-6000i

  * SLA-5500

  * SLA-5520

7.1.13. Pinnacle

  * ShowCenter 200

  * SoundBridge

7.1.14. Pioneer

  * BDP-HD50-K

  * BDP-94HD

7.1.15. Roberts

  * WM201 WiFi Radio

Playing OGG audio files requres a custom mimetype, add the following to the
<extension-mimetype> section and reimport your OGGs:

<map from="ogg" to="audio/ogg"/>

Also, add this to the <mimetype-contenttype> section:

<treat mimetype="audio/ogg" as="ogg"/>

7.1.16. Roku

  * SoundBridge M1001

  * SoundBridge M2000

7.1.17. Siemens

  * Gigaset M740AV

7.1.18. Sony

  * Playstation 3

Firmware 1.80 introduces UPnP/DLNA support, add the following to the <server>
section of your configuration file to enable MediaTomb PS3 compatibility:

<protocolInfo extend="yes"/>

7.1.19. T+A

  * T+A Music Player

7.1.20. Telegent

  * TG100

The TG100 client has a problem browsing containers, where item titles exceed
101 characters. We implemented a server-side workaround which allows you to
limit the lengths of all titles and descriptions. Use the following settings in
the <server> section of your configuration file:

<upnp-string-limit>101</upnp-string-limit>

7.1.21. TerraTec

  * NOXON iRadio

  * NOXON 2 Audio

7.1.22. ZyXEL

  * DMA-1000

Some users reported problems where the DMA will show an error "Failed to
retrieve list" and the DMA disconnecting from the server. Incresing the alive
interval seems to solve the problem - add the following option to the <server>
section of your configuration file:

<alive>600</alive>

Additionally, the DMA expects that avi files are serverd with the mime type of
video/avi, so add the following to the <extensoin-mimetype> section in your
configuration file:

<map from="avi" to="video/avi"/>

Also, add this to the <mimetype-contenttype> section:

<treat mimetype="video/avi" as="avi"/>

7.2. Network Attached Storage Devices

We provide a bitbake metadata file for the OpenEmbedded environment, it allows
to easily cross compile MediaTomb for various platforms. We have successfully
tested MediaTomb on ARM and MIPSel based devices, so it should be possible to
install and run the server on various Linux based NAS products that are
available on the market.

So far two devices are shipped with a preinstalled version of MediaTomb,
community firmware versions are available for the rest.

7.2.1. Asus

  * WL500g

Use the statically linked mips32el binary package that is provided on our
download site.

7.2.2. Buffalo

  * KuroBox-HG

  * LinkStation

7.2.3. Excito

  * Bubba Mini Server (preinstalled)

7.2.4. Iomega

  * StorCenter (preinstalled)

7.2.5. Linksys

  * NSLU2

Available via Optware.

7.2.6. Maxtor

  * MSS-I

Either use the Optware feeds or the statically linked mips2el binary package
that is provided on our download site.

7.2.7. Raidsonic

  * IB-NAS4200-B

Use the statically linked binary armv4 package that is provided on our download
site.

7.2.8. Western Digital

  * MyBook

8. Running The Server

When you run MediaTomb for the first time a default configuration will be
created in the ~/.mediatomb directory. If you are using the sqlite database no
further intervention is necessary, if you are using MySQL you will have to make
some adjustments (see Configuration section for more details). To start the
server simply run "mediatomb" from the console, to shutdown cleanly press
Ctrl-C. At start up MediaTomb will print a link to the web UI.

Note:

    Internet Explorer support is limited and not yet finished. It is very
    difficult to support this browser because of a huge number of bugs in its
    javascript implementation. If you don't believe us - just visit http://
    selfhtml.org/ and see how often IE is mentioned in not following the specs
    or simply not working with certain functions and features. We recommend
    Firefox.

If you want to run a second server from the same PC, make sure to use a
different configuration file with a different udn and a different database.

After server launch the bookmark file is created in the ~/.mediatomb directory.
You now can manually add the bookmark ~/.mediatomb/mediatomb.html in your
browser. This will redirect you to the UI if the server is running.

Assuming that you enabled the UI, you should now be able to get around quite
easily.

We also support the daemon mode which allows to start the server in background,
the --user and --group parameters should be used to run the server under an
unprivileged account. A script for starting/stopping the server is provided.
