For the QSV cmdline, you can specific format inside scale_qsv, which can
be like this:
ffmpeg -hwaccel qsv -qsv_device /dev/dri/renderD128 -c:v hevc_qsv -i
1920x1080_60_yuv420p.h265 -vf
scale_qsv=w=1920:h=540:format=bgra,hwdownload,format=bgra -f null -
While, msdk now doesn't support yuv420p, so if you change the format in
above cmdline from bgra to yuv420p, the cmdline still return error. You
can list the format you need, then we can file a requirement to MSDK to
ask to support it.
