Cyber mega phone 2K: no video stream for the echo conference


#1

Hi,

I try to use native webrtc + pjsip through websocket to build a native client equal to the cyber mega phone 2K, now there’s no video appears but only audio, I think I have some mistake but I dont know what’s the root cause, following is the log from the asterisk console:

Your browser appears to have rejected the additional video stream. I’d suggest focusing on that side instead.


#3

Yes, client tells me that the video was rejected:

Hi,

I check the answer sdp created from the client side, should the “a=candidate” line behind the “m=video” cause the video not work?

I checked the network traffic and only the audio stream send from the asterisk server to the client.

You responded on a Saturday when I don’t normally work, and there is no guarantee on any response time or if you will receive a response. It’s also impolite to tag someone like that. If I have anything to add to something on here then I’ll post.


#7

Forgive my roudeness and thanks for your response.

I found that you are almost the most active one to answer the question and I was suffered from the issue for a long time. Sorry for it again.

Sincerely
Xiemin


#8

I found the root cause of the ‘a=ssrc-group’ cause the asterisk to reject to send the video stream.
After I remove the ssrc-group from the client side then it works fine. Thanks for your help again.
