(same session id and same ssrc)
It's an upstream event so that means this event is for now only
useful on pipeline sender side. Because rtppayloader and rtpaux elements
are placed upstream from the gstrtpsession.
On pipeline receiver side, gstrtpsession is the most upstream element
compared to other rtp elements like rtpauxreceive, ssrcdemux, rtpjitterbuffer
and rtpdepayloader.
useful on pipeline sender side. Because elements generating packets with the
collided SSRC are placed upstream from the gstrtpsession.
rtppayloader
------------
When handling a GstRTPCollision event, the rtppayloader has to choose another
ssrc. Actually this is the gstrtpsession that suggests him a newer ssrc through
the caps.

BYE only the corresponding source, not the whole session.

bye. But we make sure that the whole session is not itself set bye.
Because internally, gstrtpsession can manages several sources and all have
their own distinct ssrc.
For example when using rtprtxreceive, it uses one session which contains
2 internal rtpsources. One for the master stream, and one for the rtx stream.
Actually in this case there are always 3 sources because the session always
has an other internal one, maybe for rtcp but I'm still nore sure about that.
Then gstrtpsession make sure to only bye the rtx stream if this is the one
which collided.
