FFmpeg incorrectly detects the frame rate of this mpeg4-video as 30000fps.
Problem occurred some time between 19.9.2006-9.1.2007.

Running now latest svn version as of 13.03.2007.

Videos are created with Nokia E70. Correct frame rate is 15.00fps

This is what mp4info says:
mp4info version 1.5.0.1
framerate.mp4:
Track   Type    Info
1  video        MPEG-4 Simple @ L2, 9.199 secs, 461 kbps, 352x288 @ 14.566801 fps
2  audio        MPEG-4 AAC LC, 8.768 secs, 32 kbps, 16000 Hz

I've also a video where the frame rate is detected as 3750fps, ffmpeg reports:

Seems stream 0 codec frame rate differs from container frame rate: 30000.00
(30000/1) -> 3750.00 (30000/8)

And mp4info:
mp4info version 1.5.0.1
video.mp4:

The file is 54M so i'm not uploading it at this time as it's probably related.

I believe this is related:
