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