[Ffmpeg-devel] Something wrong with rate control?

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.
