About 3GP file format

[atomasxp]

Hi,

I'm converting files with nokia multimedia converter 2.0 command line toll. Sometimes after conversion 3gp file displays only still picture, maybe is possible to check this file after conversion? Or maybe i's possible to get information about 3gp file structure?

Regards, Tomas

Try doing the conversion with the Multimedia Player in the later Nokia PC Suite versions (latest is 6.5 on http://www.nokia.com/pcsuite).

Nokia Multimedia Converter 2.0 and Nokia Multimedia Player in PC Suite 6.2 and earlier had some problems converting more than about 2 minutes of video to .3gp.

The .3gp video file format is based on MPEG-4 and specified by 3GPP. You can try to find the specs from them http://www.3gpp.org/specs/specs.htm

Actually, this might be it (didn't check): http://www.3gpp.org/ftp/Specs/html-info/26244.htm
