// With Plan B SDP, an RtpTransceiver can have any number of senders and

// receivers which map to a=ssrc lines in the m= section.

// With Unified Plan SDP, an RtpTransceiver will have exactly one sender and one

// receiver which are encapsulated by the m= section.

 备注下，以上是webrtc 官方的注释，看来我的理解应该没错，给有同样疑惑的人。

慕苞米地里吃过亏

头注释是这样的。 // Thus, the methods that only need to implement // public API features and are not used internally can assume exactly one sender // and receiver. 也就是说为了便于理解，再PeerConnection内部使用RtpReceiver，假设只有1个sender和1个receiver，并不是真的只能1个
