Add .3gp as supported format/file extension

[RR]

Films produced with Sony Ericsson mobile phone.
The clips are shiwn correctly in the player, but there is no sound.
There is sound when plaing the same clip on the phone.

I can provide one of my private clips on mail to a developer if anyone wants to have a look at the sound issue.

If you compile libFFmpeg(used by VLC)with amr support you will get audio, at least if you use Linux. I don't know about other OS.
