Méthodes publiques

Méthode Description
Close ( ) : void

Closes the session's RTP and control ports.
DateTimeToNptTimestamp32 ( System.DateTime value ) : uint
RTPChannel ( ) : System
RTPChannel ( IPEndPoint remoteEndPoint ) : System
ReservePorts ( ) : void
ReservePorts ( int startPort, int endPort ) : void

Attempts to reserve the RTP and control ports for the RTP session.
SendAudioFrame ( byte payload, uint frameSpacing, int payloadType ) : void

Sends an audio frame where the payload size is less than the maximum RTP packet payload size.
SendH264Frame ( byte frame, uint frameSpacing, int payloadType ) : void

H264 frames need a two byte header when transmitted over RTP.
SendJpegFrame ( byte jpegBytes, int jpegQuality, int jpegWidth, int jpegHeight, int framesPerSecond ) : void

Helper method to send a low quality JPEG image over RTP. This method supports a very abbreviated version of RFC 2435 "RTP Payload Format for JPEG-compressed Video". It's intended as a quick convenient way to send something like a test pattern image over an RTSP connection. More than likely it won't be suitable when a high quality image is required since the header used in this method does not support quantization tables.
SendRTPRaw ( byte payload ) : void

Sends a packet to the RTSP server on the RTP socket.
SendVP8Frame ( byte frame, uint frameSpacing, int payloadType ) : void

Sends a dynamically sized frame. The RTP marker bit will be set for the last transmitted packet in the frame.
SetFrameType ( FrameTypesEnum frameType ) : void

Video frames use a header at the start of the RTP payload in order to break up a single video frame into multiple RTP packets. The RTP channel will need to know the type of header being used in order to determine when a full frame has been received.
Start ( ) : void

Starts listenting on the RTP and control ports.
