RTPPacket

packet

This class represents an RTP data packet. Real data can either be encapsulated, or simulated by adding length.

The following RTP header fields exist but aren't used: padding, extension, csrcCount. The csrcList can't be used because csrcCount is always 0.

Fields

Name	Type	Description
byteLength		12-byte fixed header
version	uint8	The rtp version of this RTPPacket.
padding	bool	Set to 1 if padding is used in this RTPPacket, 0 otherwise. This implementation doesn't use padding bytes, so it is always 0.
extension	bool	Set to 1, if this RTPPacket contains an rtp header extension, 0 otherwise. This implementation doesn't support rtp header extensions, so it is always 0.
marker	bool	The marker.
payloadType	int8	The type of payload carried in this RTPPacket.
sequenceNumber	uint16	The sequence number of this RTPPacket.
timeStamp	uint32	The rtp time stamp of this RTPPacket.
ssrc	uint32	The ssrc identifier of the creator of this RTPPacket.
csrc	uint32[]	no mixers, no contributing sources
headerLength	int
payloadLength	int
