> (I still wonder why jkqxz couldn't reproduce and why users didn't report
this issue earlier - when was mfx support added?)
It depends on resolution, not sure Mark(jkqxz) tried the specified
resolution (1920x1080) or not.
About reasons why users didn't report this issues earlier, I guess should
be:
1. Encoding from a raw nv12 video is not a very common case. Transcoding
is more common case. Or encoding from a yuv420 rawvideo.
2. If someone want to encode from a nv12 raw video, the may use a system
memory pipeline without hwuploading, just like
https://trac.ffmpeg.org/ticket/5708.
