latest SVN versions seem to incorrectly calculate the fps rate of some .mp4 
files I have (the videos were made with Nokia mobile phones):

VIDEO:  [mp4v]  320x240  24bpp  30000.000 fps    0.0 kbps ( 0.0 kbyte/s)

The fps is off by a factor of 2000, the correct fps is about 15. This 
breaks for example -framedrop. Quicktime reports the fps correctly.

The sample file which you can check yourself is available here:
