[FFmpeg-devel] [PATCH 1/4] avcodec/amfenc: Fixes the color information in the output.

[Araz Iusubov <primeadvice@gmail.com>]

From: Michael Fabian 'Xaymar' Dirks <michael.dirks@xaymar.com>

added 10 bit support for amf hevc.

before:

command - ffmpeg.exe -hide_banner -y -hwaccel d3d11va -hwaccel_output_format d3d11 -i test_10bit_file.mkv -an -c:v h264_amf res.dx11_hw_h264.mkv
output -  Format of input frames context (p010le) is not supported by AMF.
command - ffmpeg.exe -hide_banner -y -hwaccel d3d11va -hwaccel_output_format d3d11 -i test_10bit_file -an -c:v hevc_amf res.dx11_hw_hevc.mkv
output -  Format of input frames context (p010le) is not supported by AMF.

after:

command - ffmpeg.exe -hide_banner -y -hwaccel d3d11va -hwaccel_output_format d3d11 -i test_10bit_file -an -c:v h264_amf res.dx11_hw_h264.mkv
output -  10-bit input video is not supported by AMF H264 encoder
command - ffmpeg.exe -hide_banner -y -hwaccel d3d11va -hwaccel_output_format d3d11 -i test_10bit_file -an -c:v hevc_amf res.dx11_hw_hevc.mkv
output -  10bit file

v2 - lost line returned in ff_amf_pix_fmts
v3 - fixes after review
v4 - extract duplicated code, fix incorrect processing of 10-bit input for h264
v5 - non-functional changes after review
