Fix#2751, updates remote track's rtx ssrc for
simulcast track doesn't contain rtx ssrc in sdp
since readRTX relies on rtx ssrc to determine if
it has a rtx stream.
In the case where a remote track is sending PCMU with payload type 0
checkAndUpdateTrack will fail to update the track codec and params
(because t.PayloadType() is already 0). Add an extra check to handle
this case.
This gives an option to raise the receive MTU as SettingEngine option.
If SettingEngine has not been set the MTU, then default value is used
instead, 1460
Resolves#1925
- Refine RTPReceiver.SetReadDeadline behavior
Instead of iterating over r.tracks, just calling r.tracks[0]
directly. This behavior follows RTPReceiver.Read.
- Add RTPReceiver.SetReadDeadlineSimulcast
Its fingerprint follows RTPReceiver.ReadSimulcast.
- Refine RTPReceiver.setRTPReadDeadline
It will only timeout the RTP stream for the track makes the call.
Previously, Reading RTP or RTCP packets from a peer
would block until a packet was received, or the
connection was terminated. This change allows you to
set a deadline, after which the read function will
return a timeout error and you can get on with other
things.
