[FFmpeg-user] AMD screen record + h/w vaapi encode to mkv fails.

Sat Feb 24 02:40:38 EET 2018

Haven't had time to bisect, but I can't screengrab to mkv any more.
kmsgrab + playing with vsync etc. give the same error as this example, 
mp4 works OK.

-video_size 1920x1080 -i :0 -vf 'format=nv12,hwupload' -c:v h264_vaapi
