Hi,

seems there is a lot of confusion about mpeg4 support.
So I created this bug to track the status of it ...

This table says all :

https://01.org/linuxgraphics/community/vaapi


Today driver supports h264 ( https://en.wikipedia.org/wiki/MPEG-4_Part_10 )
but not legacy format ( https://en.wikipedia.org/wiki/MPEG-4_Part_2 )

This has been reported in the mailing list too :
http://lists.freedesktop.org/archives/libva/2013-January/001489.html

So, Is support for this codec planned in the future ? 


Note I came to this probem while trying to playback (using gstreamer)
this test file (ffmpeg's FMP4 encoded) :

  http://blender-mirror.kino3d.org/peach/bigbuckbunny_movies/big_buck_bunny_720p_surround.avi

  big_buck_bunny_720p_surround.avi, 316Mb
  video: 1280x720 00:09:56 24fps FMP4 13Kbps
  audio: 48KHz  00:09:56 5 chanels 1Kbps 


I figured out that vaapi gstreamer decoder was not used
while it is said to support it 

  gst-inspect-1.0 vaapidecode
  (...)
  video/mpeg
  mpegversion: 4

but vainfo does not list VAProfileMP4* profile ... 
since intel driver does not support it (so far) ... 

( how can this been reported at the gst level ? )

Thank you for reading
