H.264 allows an arbitrarily large number of B-frames, but the useful number is no more than in mpeg4 (i.e. 3). Not that there's anything wrong with the patch.

Interesting?! Would you care to elaborate a bit on this? The stats of x264 tell me that the b-frames (ok, on average) are a lot smaller than the I/P frames, what am I missing here? Maybe useful for the docs? -------------- next part -------------- A non-text attachment was scrubbed...
