/* global $ */
/*
Here we do modifications of local video SSRCs. There are 2 situations we have
to handle:
1. We generate SSRC for local recvonly video stream. This is the case when we
have no local camera and it is not generated automatically, but SSRC=1 is
used implicitly. If that happens RTCP packets will be dropped by the JVB
and we won't be able to request video key frames correctly.
2. A hack to re-use SSRC of the first video stream for any new stream created
in future. It turned out that Chrome may keep on using the SSRC of removed
video stream in RTCP even though a new one has been created. So we just
want to avoid that by re-using it. Jingle 'source-remove'/'source-add'
notifications are blocked once first video SSRC is advertised to the focus.
What this hack does:
1. Stores the SSRC of the first video stream created by
a) scanning Jingle session-accept/session-invite for existing video SSRC
b) watching for 'source-add' for new video stream if it has not been
created in step a)
2. Exposes method 'mungeLocalVideoSSRC' which replaces any new video SSRC with
the stored one. It is called by 'TracablePeerConnection' before local SDP is
returned to the other parts of the application.
3. Scans 'source-remove'/'source-add' notifications for stored video SSRC and
blocks those notifications. This makes Jicofo and all participants think
that it exists all the time even if the video stream has been removed or
replaced locally. Thanks to that there is no additional signaling activity
on video mute or when switching to the desktop stream.
