Handbroms

Note: It didn't take me long to abandon the Streama project, partly because it required me to do things like this script. I now use Emby and I'd happily pay for the feature to automagically convert my media library on-the-fly. This script is still a funny example of the fairly recent multithreading in bash. :)

Bash script that runs HandBrakeCLI in parallel to process multiple files from MKV to MP4 for HTML5 video.

Requires Bash >= 4.3 for the wait -n feature.

Observe: Only supports MKV for now. Will add more filetypes as I go through my media library. I made this to convert files for use with Streama.

Usage

Will recursively convert directories, or single files.

$ handbroms.sh dir/
$ handbroms.sh file.mkv

Set max_proc_count at the top of the file for more parallel processes.

Note: I believe HandBrakeCLI already is multithreaded.

Subtitles

Will merge video and subtitles as long as name is the same, for example; video1.mkv and video1.srt will be combined with HandBrakeCLI --srt-file argument.

Install HandBrakeCLI on Fedora/CentOS

Dependencies

Install build-deps for HandBrakeCLI and mediainfo.

$ sudo dnf install opus-devel libxml2-devel jansson-devel libvorbis-devel \
	libass-devel libsamplerate-devel libtheora-devel bzip2-devel gmake

Fedora libmp3lame

On Fedora you can install lame-devel but on CentOS you might have to build it or install it from other 3rd party repos.

$ sudo dnf install lame-devel

The build-process on CentOS is straightforward, but I recommend setting --prefix=/usr/local so after install you edit /etc/ld.so.conf.d/usr_local.conf and add the path /usr/local/lib into it.

Then run ldconfig.

$ echo '/usr/local/lib' | sudo tee /etc/ld.so.conf.d/usr_local.conf
$ sudo ldconfig

This happily separates your custom built libraries from package installs.

libx264

$ sudo dnf install yasm
$ git clone --depth 1 git://git.videolan.org/x264
$ cd x264
$ ./configure --prefix=/usr/local --enable-shared
$ make
$ sudo make install
$ sudo ldconfig

Build

Now unpack and compile HandBrakeCLI, here's an example with version 1.0.1.

$ mkdir $HOME/bin
$ tar -xvjf HandBrake-1.0.1.tar.bz2
$ cd HandBrake-1.0.1
$ ./configure --disable-gtk --disable-gst
$ cd build
$ gmake
$ cp HandBrakeCLI $HOME/bin

I disable GTK and gstreamer support.

Now ensure HandBrakeCLI is in your PATH, I use $HOME/bin but that's not always included in PATH.

Install exiftool

This queries files for media info.

$ sudo dnf install perl-Image-ExifTool
