Hi Sean, Note that this patch "driver_name_map: add nouveau and radeon for Mesa Gallium" is only for VA_DISPLAY_DRM case.
About your question, all patches regarding gallium backend for vaapi have landed: http://cgit.freedesktop.org/mesa/mesa/log/src/gallium/state_trackers/va But there are still 4 patches for nouveau driver under review, to support chunk decoding: https://github.com/CapOM/mesa/commits/st_va_nouveau_chunk_decoding I have only tested with Nvidia hardware (with nouveau driver so), with https://github.com/mpv-player/mpv player and gstreamer-vaapi on videos available here: http://download.blender.org/peach/bigbuckbunny_movies/ http://playready.directtaps.net/smoothstreaming/ https://github.com/malek0512/PLS/raw/master/Tests/centaur_2.mpg http://www.h264info.com/clips.html At least for radeon it is already ready, the gallium backend for vaapi is what AMD support and maintain. Maybe they also use the bridge http://cgit.freedesktop.org/vaapi/vdpau-driver for some comparisons. Christian would be able to give more details about it. But in long terms I think this bridge will be only used by the Nvidia proprietary driver (unless they decide to provide a vaapi backend too) Regards Julien On 3 December 2015 at 22:37, Sean V Kelley <[email protected]> wrote: > Hi Julien, > > On 11/27/2015 12:53 AM, Julien Isorce wrote: > > This patch allows va_getDriverName to succeed.
