[himadri...@inextrix.com]

Hello,

I am working on dialer application based on the CSipSimple and I need help with Video integration.

Problem : I am facing problem with video transmission start or stop event

Description : 

I am working on video call between two device using asterisk, and its working fine. My requirement is to add the start or stop video transmission functionality and it is working. But If I am stop transmitting video from device "A" then i want to notify device "B" that Video transmission is now stopped from device "A", but i am not able to find any event or action in it.

So any one have idea for this issue then please help me to fixed it out. Looking for prompt reply.

Thanks in advance.

Regards,
Himadri Jethva

Hi Himadri,

I hope a re- INVITE sip message or UPDATE message is responsible for updating media on far end of session. An updated sdp params will notify another end to stop video. When you stop video on device A then an re invite with sdp with media line video will not be there sent to other device will negotiate to end video there.

Thanks

Hello Varun,

Thanks for your prompt replay.

Would you like to provide me one more help that how can I identify the updated media and also media line video from my dialer application.
Is there any way to do it ?

Presently I cannot pin point the function names but there is support in pjsip for media update. Search media update offer with pjsip surely you will find a pointer to utilize this. You can also call me for further explanation.

Hi Varun,

I have gone through the CSipSimple code, but no luck.I didn't found any function which point to such event for media update, so if you have some time then please help me to reach that function. Sorry for bothering you but I really need your help in this matter.

Thanks & Regards.

Refer lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2012-july/015048.html

Here Nanang explains the same

Also see there is support for media update on re-invite or update sip method. If it is not there in CSIPSIMPLE java layer then you need to create a wrapper of it in CSIPSIMPLE and derive this method in java layer to support this.

Pjsip support can be found in www.pjsip.org/pjsip/docs/HTML/structpjsip_inv_callback.htm

But its log nothing when we print anything in that function , its just for local event of speaker on/off, mic mute/un-mute etc. Sorry but need your replay again here.
