[Asterisk-video] 3G Video Call with libh324m

[Kiran N]

Hi -,

I am trying to make a 3G 
Video Call to the Asterisk Gateway. The Call is placed and then Asterisk
 get stuck in h324m_loopback() or in Answer/mp4play. In the handset I 
can see "Waiting for Video Image" and finally may be after 15-20 seconds
 , the call get disconnected with Error 16.
I have followed steps 
mentioned in different threads trying to make configuration changes here
 and there.. but the result is same.. 

My System configuration goes like this

Asterisk: 1.6.0.5 (AMR patched)
libpri: 1.4.11.5
Dahdi: dahdi-linux-complete-2.3.0.1+2.3.0
sip.fontventa.com

Digium Card: TE220 (configured as E1)
MPEG4: mpeg4ip-1.5.0.1

Extensions.conf
[incoming]
exten => _4XXXXXXX,1,Answer()
exten => _4XXXXXXX,2,h324m_loopback()

;exten => _4XXXXXXX,1,H324m_gw(5000 at conf)

[conf]
exten => 5000,1,Answer()
exten => 5000,2,mp4play(/tmp/channels2.3gp)
exten => 5000,3,Hangup

>> mp4info /tmp/channels2.3gp
mp4info version 1.5.0.1
/tmp/channels2.3gp:
Track   Type    Info
1       video   H.263, 60.100 secs, 49 kbps, 176x144 @ 10.000000 fps
2       hint    Payload H263-2000 for track 1
 Metadata Tool: mp4creator 1.5.0.1

I am attaching the logs generated in /tmp here with the mail

Are there
 any more configuration changes that is required? or any of the components are incompatible with another one? 


Cheers,
Kiran
