[FFmpeg-devel] [PATCH 1/2] lavc/qsvdec: fix keyframes

["Xiang, Haihao" <haihao.xiang-at-intel.com@ffmpeg.org>]

From: Haihao Xiang <haihao.xiang@intel.com>

MFX_FRAMETYPE_IDR is ORed to the frame type for AVC and HEVC keyframes,
and MFX_FRAMETYPE_I is taken as keyframe flag for other codecs when
getting the output surface from the SDK, hence we may mark the output
frame as keyframe accordingly.
