I continue from the last point above with a similar setup for VAAPI that
I just did for Quicksync Video - QSV encoding with system ffmpeg 7.1:
https://lists.cinelerra-gg.org/pipermail/cin/2024-October/008950.html
FFmpeg supported VAAPI pixel formats and profiles:
ffmpeg -hide_banner -encoders | grep vaapi
V....D av1_vaapi AV1 (VAAPI) (codec av1)
V....D h264_vaapi H.264/AVC (VAAPI) (codec h264)
V....D hevc_vaapi H.265/HEVC (VAAPI) (codec hevc)
V....D mjpeg_vaapi MJPEG (VAAPI) (codec mjpeg)
V....D mpeg2_vaapi MPEG-2 (VAAPI) (codec mpeg2video)
V....D vp8_vaapi VP8 (VAAPI) (codec vp8)
V....D vp9_vaapi VP9 (VAAPI) (codec vp9)
ffmpeg -hide_banner -h encoder=av1_vaapi | egrep
'Supported|profile|main|high|professional'
Supported hardware devices: vaapi
Supported pixel formats: vaapi
-profile <int> E..V....... Set profile (seq_profile)
(from -99 to 255) (default -99)
main 0 E..V.......
high 1 E..V.......
professional 2 E..V.......
-tier <int> E..V....... Set tier (seq_tier) (from
0 to 1) (default main)
main 0 E..V.......
high 1 E..V.......
ffmpeg -hide_banner -h encoder=hevc_vaapi | egrep
'Supported|profile|main|high|professional'
Supported hardware devices: vaapi
Supported pixel formats: vaapi
-profile <int> E..V....... Set profile
(general_profile_idc) (from -99 to 255) (default -99)
main 1 E..V.......
main10 2 E..V.......
-tier <int> E..V....... Set tier
(general_tier_flag) (from 0 to 1) (default main)
main 0 E..V.......
high 1 E..V.......
ffmpeg -hide_banner -h encoder=h264_vaapi | egrep
'Supported|profile|main|high|professional'
Supported hardware devices: vaapi
Supported pixel formats: vaapi
-quality <int> E..V....... Set encode quality
(trades off against speed, higher is faster) (from -1 to INT_MAX)
(default -1)
-profile <int> E..V....... Set profile (profile_idc
and constraint_set*_flag) (from -99 to 65535) (default -99)
main 77 E..V.......
high 100 E..V.......
high10 110 E..V.......
Supported pixel formats tell just "vaapi" and not more info about them
as corresponding QSV do.
The libva implementation and tools give more detailed info about the
available pixel formats for encoding:
vainfo | grep VAEntrypointEncSlice
libva info: VA-API version 1.22.0
libva info: Trying to open /usr/lib64/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_22
libva info: va_openDriver() returns 0
VAProfileH264Main : VAEntrypointEncSliceLP
VAProfileH264High : VAEntrypointEncSliceLP
VAProfileH264ConstrainedBaseline: VAEntrypointEncSliceLP

VAProfileHEVCMain10 : VAEntrypointEncSliceLP
VAProfileVP9Profile0 : VAEntrypointEncSliceLP
VAProfileVP9Profile1 : VAEntrypointEncSliceLP

VAProfileHEVCMain444_10 : VAEntrypointEncSliceLP
VAProfileHEVCSccMain : VAEntrypointEncSliceLP
VAProfileHEVCSccMain10 : VAEntrypointEncSliceLP
VAProfileHEVCSccMain444 : VAEntrypointEncSliceLP
VAProfileAV1Profile0 : VAEntrypointEncSliceLP
VAProfileHEVCSccMain444_10 : VAEntrypointEncSliceLP
Format p010le results in "just" 10bit yuv420p.
The clue for hevc_vaapi to encode true 10bit 422p video, is found to use
(trying this for av1_vaapi auto-switch to 8bit p010):
-vf 'format=y210,hwupload'
After troubleshooting a useable profile, rendering went on by simply
leaving profile out:
Example ffmpeg 7.1 simple code line for hevc_vaapi encoding (without audio):
ffmpeg -hide_banner -vaapi_device /dev/dri/renderD128 -i cfhd01.mkv -vf
'format=y210,hwupload' -c:v hevc_vaapi cfhd01_hevc_vaapi_format_y210.mp4
