We are trying to test JVB but have not embraced simulcast yet. In the past
(say, as of last August) we were able to send multiple unrelated streams on
a single video channel. With the latest code, we can still send multiple
streams in a video channel, but the FIR logic doesn't get triggered
properly in all cases.
What we see happening when a user joins an existing conference is that one
of the video streams on a channel starts immediately, while another stream
on that channel languishes until a keyframe comes through.
So it seems that the VideoChannel/BitrateController implementation assumes
that there is only one video stream per endpoint. Is this understanding
