[FFmpeg-devel] [PATCH] lavu/hwcontext_qsv: add 10-bit RGB support for QSV

[Linjie Fu]

After adding a copy pass through path inside MSDK, x2rgb10 is now
available as an output of VPP.

Command line for CSC:
ffmpeg -hwaccel qsv -v verbose -c:v hevc_qsv -i
    p010.h265 -vf scale_qsv=format=x2rgb10,hwdownload,format=x2rgb10
    -vframes 1 out.yuv
