Description Lorenz Kiefner 2005-07-13 02:55:37 UTC
Dirac is the open-source video codec developed at the BBC. They provide patches
for ffmpeg, mplayer and transcode as well as a command-line tool for encoding
files, which is already in portage.
Please add a USE-Flag.

Reproducible: Always
Steps to Reproduce:




The Patches are available at
http://sourceforge.net/project/showfiles.php?group_id=102564
Comment 1 Diego Elio Pettenò (RETIRED) gentoo-dev 2005-07-13 03:38:35 UTC
Patches not merged upstream aren't going to be applied on portage versions.  
  
Also, dirac support in VLC is not enabled as there's no sample to test with. 
 
When ffmpeg, mplayer and transcode will support dirac upstream, they'll 
support it on gentoo.

They doesn't seems to be dirac-encoded files but better files to use to 
process and create the dirac file (thing that i wasn't able to do actually). 
 
If they are already dirac-encoded, vlc doesn't recognize them.

OT, but still:

Well, you still have that half-broken mythtv patch.
If somebody can provide me with this kind of (non-MPEG) MythTV samples, I might
fix and merge it upstream.

As provided. I have adapted some ebuilds, ffmpeg-cvs (from ebuild-exchange), mplayer (gentoo) and created a dirac-cvs (ebuild exchange). This sample (black background, Arjen & Hildo in spotlight) is the start of a broadcast filler, animated as png in Blender (200K) converted lossless with the (very good) dirac_encoder.py script (75K). Some modifications where made in order to get Blender output to work as good as Lives output.

It plays now in a patched mplayer version.

I talked on #videolan, it seems VLC won't accept raw (unmuxed) streams of Dirac, so if you could embed them in lets say Ogg (that is supported) the video would play. I think it is time to sleep now ;) and dream about someone to open these bugs :)
