[FFmpeg-devel] [PATCH] libavcodec/qsvenc_hevc: add main10sp support to hevc_qsv

[Wenbin Chen <wenbin.chen-at-intel.com@ffmpeg.org>]

Main10sp is a combination of Main10 and one_pic_only flag.
This profile encode 10bit single still picture.
A option "main10sp" is added to ffmpeg-qsv. This option
set MFX_PROFILE_HEVC_MAIN10  profile and
MFX_HEVC_CONSTR_REXT_ONE_PICTURE_ONLY flag to enable main10sp
in ffmpeg-qsv.
