An overview over the system FFmpeg 7.x supported QSV pixel
formats and profiles:
ffmpeg -hide_banner
-h encoder=hevc_qsv | egrep 'Supported|profile|main'
Supported hardware devices: qsv qsv qsv
Supported pixel formats: nv12 p010le p012le yuyv422 y210le
qsv bgra x2rgb10le vuyx xv30le
-profile <int> E..V....... (from 0 to
INT_MAX) (default unknown)
main 1 E..V.......
main10 2 E..V.......
mainsp 3 E..V.......
main 0 E..V.......
ffmpeg -hide_banner -h encoder=h264_qsv | egrep
'Supported|profile|main'
Supported hardware devices: qsv qsv qsv
Supported pixel formats: nv12 qsv
-profile <int> E..V....... (from 0 to
INT_MAX) (default unknown)
main 77 E..V.......
I think we can concentrate on av1 for now.
does it fail if you add "-profile main" to ffmpeg command line for dv av1 encode?
dv due to it being software codec, so ffmpeg forced to push and convert frames from system memory, as opposed to hdv (hw) = > av1 on-gpu transcode)
hevc_qsv and h264_qsv
encoders also have "high" profile:
ffmpeg -hide_banner -h encoder=hevc_qsv | egrep
'Supported|profile|main|high'
Supported hardware devices: qsv qsv qsv
Supported pixel formats: nv12 p010le p012le yuyv422 y210le qsv
bgra x2rgb10le vuyx xv30le
-profile <int> E..V....... (from 0 to
INT_MAX) (default unknown)
main 1 E..V.......
main10 2 E..V.......
mainsp 3 E..V.......
-tier <int> E..V....... Set the
encoding tier (only level >= 4 can support high tier) (from 0
to 256) (default high)
main 0 E..V.......
high 256 E..V.......
ffmpeg -hide_banner -h encoder=h264_qsv | egrep
