[Asterisk-video] Asterisk Video Playback - MP4 ad 3GP files

[LL]

Hi There,
I'm fairly new to asterisk and I'm trying to play a video file during a 
video call without success for a couple of days now.
I've posted a question at stack-overflow describing my problem - 
http://stackoverflow.com/questions/8675713/asterisk-video-playback-mp4-3gp
*
In short, what are the exact specs that a 3gp or mp4 file needs to have 
in order to play under asterisk ?*
Any tips, links or suggestions will be very welcome.

*Thank you all!
LL
