New issue 153 by leon.pol...@gmail.com: How to compensaet dropped frames
http://code.google.com/p/mp4v2/issues/detail?id=153

Hello, all.
I have my device which captures PAL frames and H.264 encodes them. The
encoder output I next feed to the mp4v2 library.
Everything goes perfect, till the case when the device drops some frames
(thus we have, for example, 20 fps instead of 25fps). As the result, the
total mp4 movie becomes 20% shorter than the reality.
I tried several ways to compensate the lack of these frames, but none of
the ways was successful.

I shall be very thankful for any advice how can I solve this by means of
MP4 parameters.

For those who will follow this from the Internet: correct the "Duration"
field.

Sounds like you figured it out, but you're correct: as long as duration is
compensated for, the resulting file should end up okay
