[FFmpeg-cvslog] r14335 - trunk/libavcodec/h264.c

[michael]

Author: michael

New Revision: 14335

Log:
Setting chroma_qp to 0 for PCM blocks is really a interresting minor
optimization, more interresting would it have been had the author
thought about what value chroma_qp would have for the following MB.
Or failing that, had actually tested the code.
So this reverts this non functional optimization, and makes the code
work.
Fixes at least CAPM3_Sony_D.jsv
