Comment 16 for bug 997370

julius - Isn't that a Haswell processor? Ubuntu 13.04 was released with version 1.0.17-1 of the va-api driver. According to http://lists.freedesktop.org/archives/libva/2012-November/001420.html Haswell support was not added until version 1.0.19 of the va-api driver.

According to http://lists.freedesktop.org/archives/gstreamer-devel/2013-April/040527.html MPEG-4:2 support was present in gstreamer-va-api 0.5.3 (earlier than I mentioned in comment #11). MPEG4 support seems to have been present since the original gstreamer-va-api release, but I'm unsure of which part of MPEG4.
