Hi,
Anthon, thank you for your review.
I've just submitted to the patchwork a new patchset (v14
https://patchwork.ffmpeg.org/project/ffmpeg/list/?series=7794) containing
changes following your review. If something still needs to be changed
please let me know.
I will be grateful for your feedback.

When called inside a loop, the inline asm version results in one pxor
unnecessarely emitted per iteration, as the contents of the __asm__() block are
opaque to the compiler's instruction scheduler.
This is not the case with intrinsics, where pxor will be emitted once with any
half decent compiler.
Should speed up parsing when the frames come from non raw containers.

The got_frame variable can probably be removed. ff_combine_frame() should return
success only if the end of a frame was found. Will look at that later.

Missing SEI information has always been a major drawback when using the QSV
decoders. It turned out that there's a hardly known api method that provides
access to all SEI (h264/hevc) or user data (mpeg2video).
This allows to get things like closed captions, frame packing, display
orientation, HDR
