Hi,
Am writing a 3gp file parser which takes 3gp file path as input and
return H263 comressed video frames and other timing information as out
put.

My question is how do we find framerate of 3GP file?  Is there any
particular box present in 3gp file to specify framerate?

Thanks

Hi,
3gp is actually QuickTime file. You can try my QuickTime Atom Viewer :

There is no special field for Frames Per Second, so you have to
calculate by deviding the number of frames in stream and stream time
duration.
