Hello All, Current implementation of libavcodec/qsvdec_h264.c does use external SPS parser. It does not optimal since MFX library has own unified way to parse headers of all supported formats. This performs by one MFXVideoDECODE_DecodeHeader() call. The suggested patch does replace stream specific code to one universal function call located into the libavcodec/qsvdec.c. This opens an easy way to implement qsv-accelerated mpeg2, hevc and vc1 decoders. Please review.
