    21 // RtspChannelChild is a dummy channel used to aid MediaResource creation in

    22 // HTMLMediaElement. Network control and data flows are managed by an

    23 // RtspController object, which is created by us and manipulated by

    24 // RtspMediaResource. This object is also responsible for inter-process

    25 // communication with the parent process.

    26 // When RtspChannelChild::AsyncOpen is called, it should create an

    27 // RtspController object, dispatch an OnStartRequest and immediately return.

    28 // We expect an RtspMediaResource object will be created in the calling context

    29 // and it will use the RtpController we create.
