Vaapi hardware decoding 444 HEVC failure

[kebs00n]

Hello. I'm trying to hardware decode 444 HEVC video frame using VAAPI, but it always fallback in software decoding with this error

% ./ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -y -i ../chromium-video-format-tests/media/test/data/blackwhite_yuv444p-frame.hevc 444.yuv -report

444 HEVC video frame sample

[Jun Zhao]

If my memory is correct, VAAPI does not support the YUV444 format

[Fei Wang]

You may need to update your VAAPI/media-driver version. HEVC 444 supported after VAAPI 1.2.0.
