[Ffmpeg-devel] [patch] ffmpeg fails to create a mov, example file

[Marcus Engene]

If you'd like an example file that doesn't work well before the patch, 
please use ehsmeng.se/bug.mov (26MB). It's the one I used to get the 
behaviour below.

ffmpeg -v 9 -i bug.mov -acodec mp3 apa.mov

Hi list,

I have a problem with ffmpeg, I try to convert a dv->mov/mpeg4 but it 
only results in one frame in the beginning. It used to work fine.
I traced the problem to have been created on the 20050329->20050330. I 
attach a patch that makes it work for me. The patch is how it looked in 
the 20050329 version. I haven't done any deeper investigations.

My machine is a AMD64, Linux Fedora Core 3 if that would be relevant.

Best regards,
Marcus

Here is the ffmpeg output

after correction:
