[FFmpeg-devel] [PATCH] Implement PAFF in H.264
Sun Oct 14 21:17:00 CEST 2007
There is special case for deblocking top- and left-most macroblocks
in the ffmpeg implementation. The problem is in the condition, which
tests macroblock y-coordinate for equation to 0, and in y-coordinate
of top-most macroblocks in bottom fields, where the coordinate is 1.
The attached patch fixes this problem - the condition is fulfilled
for top-most macroblocks in both top and bottom fields.
Decoded I-frames (fields in fact) should be equivalent to those
decoded by the reference decoder now.
P-frames are still different...
