 // This class maintains a send transport for audio and video in a Cast
 // Streaming session.
 // Audio, video frames and RTCP messages are submitted to this object
 // and then packetized and paced to the underlying UDP socket.
 //
 // The hierarchy of send transport in a Cast Streaming session:
 //
 // CastTransportSender              RTP                      RTCP
 // ------------------------------------------------------------------
 //                      TransportEncryptionHandler (A/V)
 //                      RtpSender (A/V)                   Rtcp (A/V)
 //                                      PacedSender (Shared)
 //                                      UdpTransport (Shared)
 //
 // There are objects of TransportEncryptionHandler, RtpSender and Rtcp
 // for each audio and video stream.
 // PacedSender and UdpTransport are shared between all RTP and RTCP
 // streams.

Need to document the new options.
