TODO
5.1. addTransceiver
- Adding a transceiver will cause future calls to createOffer to add a media
description for the corresponding transceiver, as defined in [JSEP]
(section 5.2.2.).
- Setting a new RTCSessionDescription may change mid to a non-null value,
as defined in [JSEP] (section 5.5. and section 5.6.).
1. If the dictionary argument is present, and it has a streams member, let
streams be that list of MediaStream objects.
5.2. RTCRtpSender Interface
Create an RTCRtpSender
3. Let sender have an [[associated MediaStreams]] internal slot, representing
a list of MediaStream objects that the MediaStreamTrack object of this
sender is associated with.
4. Set sender's [[associated MediaStreams]] slot to streams.
5. Let sender have a [[send encodings]] internal slot, representing a list
of RTCRtpEncodingParameters dictionaries.
6. If sendEncodings is given as input to this algorithm, and is non-empty,
set the [[send encodings]] slot to sendEncodings. Otherwise, set it to a
list containing a single RTCRtpEncodingParameters with active set to true.
5.3. RTCRtpReceiver Interface
Create an RTCRtpReceiver
4. If an id string, id, was given as input to this algorithm, initialize
track.id to id. (Otherwise the value generated when track was created
will be used.)
Tested in RTCPeerConnection-onnegotiationneeded.html
5.1. addTransceiver
12. Update the negotiation-needed flag for connection.
Out of Scope
5.1. addTransceiver
8. If sendEncodings is set, then subsequent calls to createOffer will be
configured to send multiple RTP encodings as defined in [JSEP]
(section 5.2.2. and section 5.2.1.).
When setRemoteDescription is called with a corresponding remote
description that is able to receive multiple RTP encodings as defined
in [JSEP] (section 3.7.), the RTCRtpSender may send multiple RTP
encodings and the parameters retrieved via the transceiver's
sender.getParameters() will reflect the encodings negotiated.
9. This specification does not define how to configure createOffer to
receive multiple RTP encodings. However when setRemoteDescription is
called with a corresponding remote description that is able to send
multiple RTP encodings as defined in [JSEP], the RTCRtpReceiver may
receive multiple RTP encodings and the parameters retrieved via the
transceiver's receiver.getParameters() will reflect the encodings
negotiated.
