[Asterisk-code-review] bridge: Change participant SFU streams when source streams c... (asterisk[15])

[Joshua Colp]

Hello Jenkins2, Sean Bright, 

I'd like you to reexamine a change. Please visit

    https://gerrit.asterisk.org/6529

to look at the new patch set (#2).

Change subject: bridge: Change participant SFU streams when source streams change.
......................................................................

bridge: Change participant SFU streams when source streams change.

Some endpoints do not like a stream being reused for a new
media stream. The frame/jitterbuffer can rely on underlying
attributes of the media stream in order to order the packets.
When a new stream takes its place without any notice the
buffer can get confused and the media ends up getting dropped.

This change uses the SSRC change to determine that a new source
is reusing an existing stream and then bridge_softmix renegotiates
each participant such that they see a new media stream. This
causes the frame/jitterbuffer to start fresh and work as expected.

ASTERISK-27277
