[Asterisk-video] No Audio . Video when running app_mp4

[Emmanuel Fauvet]

Hi,

 

I think there is a problem with your video file

 

Try this with an mpeg2 or mpeg4 (with sound)   :

 

ffmpeg -i source.mpeg -an -vcodec h263 -r 10 -s qcif -b 40K -g 50  tmp.mp4  

mplayer -vo null -ao pcm -af resample=8000 source.mpeg

ffmpeg -i tmp.mp4 -b 40K -i audiodump.wav  -ac 1  dest.mp4

mp4creator –hint=1 dest.mp4

mp4creator –hint=2 dest.mp4

 

Greetings

 

Emmanuel

Could you run mp4info on the file?
