1.24 +// RtspChannelChild is a dummy channel used to aid MediaResource creation in
1.25 +// HTMLMediaElement. Network control and data flows are managed by an
1.26 +// RtspController object, which is created by us and manipulated by
1.27 +// RtspMediaResource. This object is also responsible for inter-process
1.28 +// communication with the parent process.
1.29 +// When RtspChannelChild::AsyncOpen is called, it should create an
1.30 +// RtspController object, dispatch an OnStartRequest and immediately return.
1.31 +// We expect an RtspMediaResource object will be created in the calling context
1.32 +// and it will use the RtpController we create.
