HOgg -- Ogg encapsulation stuffz
------------------------------------------------------------
Requirements:
- Cabal (tested with various version from 1.1.3 to 1.6.0)
- Data.ByteString, included with GHC >= 6.6, and available separately
for GHC 6.4 at:
http://www.cse.unsw.edu.au/~dons/fps.html (version 0.7 or greater)
If building on Debian GNU/Linux:
$ apt-get install ghc6 libghc6-mtl-dev libghc6-hunit-dev
$ apt-get install libghc6-cabal-dev # not needed for Debian unstable
Optional:
- HTTP1 with lazy bytestring support, from:
http://www.dtek.chalmers.se/~tox/site/http.php4
To configure with HTTP support, first install the above library, then
go install through Cabal, but run configure like
$ runhaskell Setup configure --flags="http"
Building:
This package is configured by default to build with GHC 6.8.
If you are building with GHC 6.6, you need to follow the usual Cabal
setup but run configure like:
$ runhaskell Setup configure --flags="-splitBase"
If you are building with GHC 6.4, you will need to edit hogg.cabal
by adding 'fps' to the Build-Depends line and probably remove the Cabal
conditionals. You should consider upgrading to a more recent GHC.
Once configured, the following procedure will build hogg:
$ chmod +x Setup.hs
$ ./Setup.hs configure
$ ./Setup.hs build
$ ./Setup.hs install
Usage:
General help (lists subcommands):
hogg help
Help on a subcommand:
hogg help <subcommand>
Info about the various tracks of one or more files:
hogg info file1.ogg file2.ogg ...
Dump packets of an Ogg file:
hogg dump file1.ogg file2.ogg ...
Dump pages of an Ogg file
hogg pagedump file1.ogg file2.ogg ...
Dump vorbis (theora, speex) packets
hogg dump -c vorbis file.ogg ...
hogg pagedump -c vorbis file.ogg ...
hogg dumpraw -c vorbis file.ogg ...
Chop out part of a file
hogg chop --start 01:10 --end 2:30 -o output.ogg file.ogg
Merge
merge pages from many input files and produce a single output file:
hogg merge -o output.ogg file1.ogg file2.ogg file3.ogg ...
Checking stuff works:
Rewrite a file (parse pages, rewrite page data):
hogg rip file.ogg > newfile.ogg
diff file.ogg newfile.ogg
Repacket a file (parse to packets, rewrite with original segmentation):
hogg reconstruct file.ogg > newfile.ogg
diff file.ogg newfile.ogg
