|
// transport to/from a remote endpoint. We should have separate
|
|
// interfaces for send and receive side, even if they are implemented
|
|
// by the same class. This is an ongoing refactoring project. At some
|
|
// point, this class should be promoted to a public api under
|
|
// webrtc/api/rtp/.
|
|
//
|
|
// For a start, this object is just a collection of the objects needed
|
|
// by the VideoSendStream constructor. The plan is to move ownership
|
|
// of all RTP-related objects here, and add methods to create per-ssrc
|
|
// objects which would then be passed to VideoSendStream. Eventually,
|
|
// direct accessors like packet_router() should be removed.
|
|
//
|
|
// This should also have a reference to the underlying
|
|
// webrtc::Transport(s). Currently, webrtc::Transport is implemented by
|
|
// WebRtcVideoChannel and WebRtcVoiceMediaChannel, and owned by
|
|
// WebrtcSession. Video and audio always uses different transport
|
|
// objects, even in the common case where they are bundled over the
|
|
// same underlying transport.
|
|
//
|
|
// Extracting the logic of the webrtc::Transport from BaseChannel and
|
|
// subclasses into a separate class seems to be a prerequesite for
|
|
// moving the transport here.
