I've experienced the same with mplayer and h264 encoded files from
cinelerra, output format was Quicktime for Linux.
Mplayer shows fps 500 or 600.
I also built cinelerra-cvs, with ffmpeg taken from cvs around beginning of
november (the ffmpeg directory structure in cinelerra-cvs is different
from ffmpegs' structure (I wonder why?), so I just diffed and copied the
changed files to the cinelerra-cvs tree), but results were the same.
Also when I encode h264 files with ffmpeg (from commandline) with bitrate
>2000kbits/s, mplayer can't play them properly, it reports that my computer
is too slow, although it's using only about 20-30% of cpu while playing,
and the video is very slow, audio plays fine.
Files with bitrate <1500kbps play just fine.
