Hi Sergio!

I record an 3gp (from Nokia 6630) file with mp4save.

The file looks good:
# mp4info record_nokia6630.3gp
mp4info version 1.5.0.1
record_nokia6630.3gp:
Track   Type    Info
1       audio   AMR, 11.420 secs, 12 kbps, 8000 Hz
2       hint    Payload AMR for track 1
3       video   H.263, 3.677 secs, 127 kbps, 176x144 @ 21.484906 fps
4       hint    Payload H263-1998 for track 3

After that I try to playback this file with mp4play() - again to the 
Nokia 6630. Then Asterisk crashes:

Then I removed the hint tracks from the recorded file and added new hint 
tracks. Then Asterisk does not crash, but playback does still not work:

The only working 3gp file yet I have produced with helix mobile producer 
trial version. I also tried Quicktime Pro - audio works but video is 
very bad quality (on the mobile on even on the PC) - looks like 
Quicktime's encoder is bad.

Do you have any hints how to make a good 3gp file with ffmpeg and 
mpeg4ip? How do I have to build ffpmeg (configure options, patches) and 
mpeg4ip? What are the proper commands to transcode a video?

thanks
