[FFmpeg-devel] h264 speed regression after PAFF

[Andreas Öman]

Hi

After the PAFF code got in h264 is about 3% slower for non-interlaced
content. See test below.

The offending diffs are
svn diff -r10679:10690 (changes in deblock_mb_fast())
svn diff -r10691:10696 (The "enable" patch)

The "enable" patch can obviously not be blamed on its own.

Either way, I find this a little too much. Michael, whats your opinion?

I haven't tried to fix this (yet), i just want the share
the output from the test.

Jeff, you mentioned earlier that you was going to address the
(MB_MBAFF || FIELD_PICTURE) -stuff. Are you working on this
or are there still remaining bugs that needed to be squashed?
