5.2. replaceTrack
|
||||
To avoid track identifiers changing on the remote receiving end when
|
||||
a track is replaced, the sender must retain the original track
|
||||
identifier and stream associations and use these in subsequent
|
||||
negotiations.

Non-Testable

5.2. replaceTrack

10. Run the following steps in parallel:
|
||||
1. Determine if negotiation is needed to transmit withTrack in place
|
||||
of the sender's existing track.
|
||||
|
||||
Ignore which MediaStream the track resides in and the id attribute
|
||||
of the track in this determination.
|
||||
|
||||
If negotiation is needed, then reject p with a newly created
|
||||
InvalidModificationError and abort these steps.
|
||||
|
||||
2. If withTrack is null, have the sender stop sending, without
|
||||
negotiating. Otherwise, have the sender switch seamlessly to
|
||||
transmitting withTrack instead of the sender's existing track,
|
||||
without negotiating.

3. Queue a task that runs the following steps:

1. If connection's [[isClosed]] slot is true, abort these steps.
