Yes: this patch <https://lists.libav.org/pipermail/libav-devel/2016-September/079207.html> is also required to match the vaSyncSurface() change. The rest of the that series to libav and the one to mesa for config setup makes it all a bit more sensible (doesn't submit a load of packed headers which are ignored), but it does mostly work without. With all of those, the commands: ./avconv -y -vaapi_device /dev/dri/renderD129 -i in.mp4 -an -vf 'format=nv12,hwupload' -c:v h264_vaapi -bf 0 out.mp4 ./avconv -y -vaapi_device /dev/dri/renderD129 -hwaccel vaapi -hwaccel_output_format vaapi -i in.mp4 -an -c:v h264_vaapi -bf 0 out.mp4 ./avconv -y -vaapi_device /dev/dri/renderD129 -hwaccel vaapi -hwaccel_output_format vaapi -i in.mp4 -an -vf 'scale_vaapi=w=1280:h=720' -c:v h264_vaapi -bf 0 out.mp4 work sensibly for me (also with -b for CBR, -qp for CQP, -g for GOP size); I imagine raw video as in your example would also be fine. On profile, constrained baseline on the command line is 578 (== 66 | 0x200, for constraint_set1_flag).
