[jitsi-dev] How could I know if simulcast is working?


#1

I use chrome to connect to https://meet.jit.si/1122 and use iOS app connect
room 1122. The connect is successful.

then I use chrome://webrtc-internals/ to debug webrtc. I have saw
there is "a=ssrc-group:SIM
520108903 4199489430 3531909241" in the setLocalDescription and "
a=x-google-flag:conference" in the setRemoteDescription.

So I want to know, how do I know the simulcast in chrome is working.

Could I use any tool to check the video streams is sending to server?

the other question is why there is only one sending for video, and three
for recv. for example:
ssrc_520108903_send
ssrc_1995837255_recv
ssrc_1528277143_recv
ssrc_2081534796_recv
As the document said ,there should be many video stream sending to
videoBridge
