[Ffmpeg-devel] Apple h264 compatibility

I've just tried some apple h264 samples, since the x264 decoder
is internal to ffmpeg I'm posting here but I could forward the request
directly to x264 ml if needed.
Anyway I've downloaded some great samples from:
http://www.apple.com/quicktime/hdgallery/

the quicktime decoder is very sloppy I think it need a cray to decode
the video, but mplayer plays it very fast, the problem is some sort of
incompatibilities but I think they are not so difficult to fix since
the movie is almost played well, there are some glitches, the debug
shows some errors for me:

and sometime the output video gets garbled, as always standard
are not standards ;(
Someone can fix this?

Bye
