Note: this isn't actually faster. pixelutils_sad_a_16x16_sse2() is ~500

overall decode is bigger when using the former. I don't get it.

This is following the comments from Michael in
https://ffmpeg.org/pipermail/ffmpeg-devel/2014-August/160599.html
Using 2 registers for accumulator didn't help. On the other hand,
some re-ordering between the movs and psadbw allowed going ~538 to ~500.

No: not for the last frame. That would leave no channel to pass the

I will include this in the merge request soon unless you object.

Hi,
the attached patch seems to fix ticket #3773, but streamcopy is such a
core feature of ffmpeg that I assume I'm missing a use case or
incorrectly handle the buffers referencing.
Another note is that this patch was developed without a memory tracer
like valgrind: I have just validated that the
