[FFmpeg-devel] [PATCH] H.264 predictive lossless: again

I'm getting rather annoyed at having to tell people to install payware
(CoreAVC) or recompile their ffmpeg with an unsupported patch in order
to play back output from x264.  So, here's the patch again, with a few
changes to make it a bit more palatable.  In particular,
transform_bypass is now counted as a "complex" block in order to
eliminate the speed impact of the changes on ordinary decoding of
non-lossless material.

Patch attached.  Another test vector can be found here
