Bug 232453 – media-video/dirac keywording request (needed for dirac useflag in vlc)

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Alexis Ballier 2008-07-20 11:18:16 UTC]

vlc 0.9 has been supporting dirac for a while, albeit it's not perfect (I get lot of debug output and the decoder is slow) I'd like to make it available as an useflag, therefore requesting keywording for arches which have vlc keyworded but not dirac. (By the way, ffmpeg trunk supports libdirac too so it might be useful for that later, I dunno what are Luca's plans for it)

Test procedure:
install dirac
EXTRA_ECONF=--enable-dirac emerge >=media-video/vlc-0.9_beta2
download files at:
http://samples.mplayerhq.hu/V-codecs/Dirac/

see if it works


Thanks.

How did you test? vlc sample.avi tells me it can't demux the file.

what sample.avi file ?

My bad. I meant th two frc files mentioned in comment #0.

On sparc it compiles fine but the two examples in comment #0 also don't work. However these files do work: http://dirac.kw.bbc.co.uk/download/video/notfinal/

Do you have some more example files we can use to test?

[Comment 6 Markus Rothe (RETIRED) 2008-08-14 06:08:55 UTC]

per comment #2 adding ppc64 back to cc. I don't recall how I've tested this...

I'll retest it ASAP (give me a day or two).

Indeed; the mplayerhq samples worked for me as they were demuxed by ffmpeg, for which I used a more recent version than the portage's one and enabled dirac support.... my bad :(

Unfortunately not, dirac format is not widespread yet (and afaik still not 100% finalized)

[Comment 8 Tobias Klausmann (RETIRED) 2008-08-14 19:29:00 UTC]

The latter files work fine here. Keyworded on alpha.

It may not have support for all dirac features yet, but the features it has do work.

Added ~sparc, looking forward to see some version bumps that allow it to play ffmpeg-dirac files :)

works as described in comment #5.

seems like I just fscked up the testing in comment #1.

Leaving ~ppc64 in and removing us from CC again.

[Comment 11 Mounir Lamouri (volkmar) (RETIRED) 2008-10-14 20:53:11 UTC]

Works for me with :
- dirac-1.0.0
- ffmpeg-0.4.9_p20080326 (~ppc)
- vlc-0.9.0_beta3 (~ppc)
(I'm using ppc, btw)

I tested files from there : http://dirac.kw.bbc.co.uk/download/video/maybefinal/ and they are working.
That's probably much more relevant than files from comment #0

I observe that was very slow. But vlc was builded in debug mode and my powerbook is getting old so it probably doesn't come from dirac.

Someone to confirm this ?
