[Asterisk-video] problem with mp4play in sip and h324m

Wed Mar 21 10:53:57 MST 2007

Hello,

I recently got h324m up and running in asterisk 1.4.
Great work btw !
When i make a call from my nokia n70 to an E1, h324m_loop works fine
and i can also see the video from my camera feeded back to me. Very
cool. So far so good.

In a next step I tried getting mp4play (and mp4save) to stream an mp4
to my mobile but i don't see anything appearing on my mobile and the
call is finished abruptly.
I tried with different hinted mp4 files created with mp4creator that
seem to play ok on vlc, so i don't think they are the culprit. I did
try playing video with mp4play through a sip videocall (xmeeting on
osx), which also does not seem to work.
I'm a bit lost as to why i can't get mp4play to work correctly ; any
pointers on what i could try next would be much appreciated !

The h324 context i use for testing is as follows

[videocalltest3]
exten => s,1,h324m_gw(s at video)

[video]
exten => s,1,Wait(4)
exten => s,2,Answer
exten => s,3,Wait(4)
exten => s,4,mp4play(/tmp/video3G/menu1.mp4)
exten => t,1,Goto(s,4)

when i call from my nokia i see the following in the logs

 == Registered application 'mp4save'
 == Registered application 'mp4play'
