[MPlayer-users] MP4 playback problem in pre8

[Casey King]

MP4's from Apple's MPEG4 video gallery play back under Linux on our MIPS
processor, but the same bitstream plays back with errors with mplayer on
OSX. In the MIPS build the video codec is detected as 'Fourcc: mp4v' and on
OSX it is detected as 'Fourcc: v4pm'. Must be an endian issue.

First snippet below is from MIPS run, second from OSX:

hmm, seems the headers arnt complete, trying to guess time_increment_bits
my guess is 15 bits ;)
