It supports ICL platform.
H2H (HDR to HDR): P010 -> A2R10G10B10
H2S (HDR to SDR): P010 -> ARGB

I believe that even if you tell me that a conversion to planar on the
gpu is impossible (why?), a slow C conversion still makes the filter
more useful.
Ping.
Thank Carl for the comment, current H2H support A2R10G10B10 output, I am
not sure H2H will support planar P010 output, I agree support P010
output will get more benefit for encode.
in another side, iHD driver already support A2R10G10B10 as input for
HEVC encode:
https://github.com/intel/media-driver/commit/6b74dac6bcb722f4cdb71b5d6a2bd0a1e5af7237
on H2S side, we can use scale_vaapi=format=nv12 to do the Conversion for
ARGB, So I think maybe ffmpeg can also do the conversion from
A2R10G10B10 to P010.
As my local test, the the conversion from A2R10G10B10 to P010 is also
works for VAAPI.
So, Do you think we add another filter to command line
"scale_vaapi=format=p010" for do the conversion after the filter
tonemap_vaapi is reasonable ?
Sorry for late reply.
