[FFmpeg-user] vaapi can't find entrypoint shown by vainfo

[sean darcy]

Giving up on qsv, I'm trying vaapi, but ffmpeg can't find the vp9 entry 
point supported by my cpu , and found by vainfo.

FWIW, hevc_vaapi works.


ffmpeg -vaapi_device /dev/dri/renderD128 -i infile.mkv -map v -map 0:2 
-vf format=nv12,hwupload -c:v vp9_vaapi -global_quality 50 -bsf:v 
vp9_raw_reorder,vp9_superframe -rc_mode 5 -r 24000/1001 -c:a copy -dn
