/// Below is an unexhausted list of Ping messages.
/// type 0: Clear the stream. No third and fourth parameters.
/// The second parameter could be 0. After the connection
/// is established, a Ping 0,0 will be sent from server
/// to client. The message will also be sent to client on
/// the start of Play and in response of a Seek or
/// Pause/Resume request. This Ping tells client
/// to re-calibrate the clock with the timestamp of the
/// next packet server sends.
/// type 1: Tell the stream to clear the playing buffer.
/// type 3: Buffer time of the client. The third parameter is the buffer time in millisecond.
/// type 4: Reset a stream. Used together with type 0 in the case of VOD. Often sent before type 0.
