Detailed Description

This class represents an rtp data packet. Real data can either be encapsulated or simulated by adding length. Following rtp header fields exist but aren't used: padding, extension, csrcCount. The csrcList can't be used because csrcCount is always 0.

cObject * RTPPacket::dup (   )  const [virtual]

Duplicates the RTPPacket by calling the copy constructor.

int RTPPacket::fixedHeaderLength (   )  [static]

Returns the length of the fixed header of an RTPPacket.

int RTPPacket::headerLength (   )  [virtual]

Returns the length of the header (fixed plus variable part) of this RTPPacket.

void RTPPacket::info (  char *  buf  )  [virtual]

Writes a one line info about this RTPPacket into the given string.

Member Data Documentation

int RTPPacket::_csrcCount [protected]

Stores the number (0..31) of contributing sources for this RTPPacket. It is always 0 because contributing sources are added by rtp mixers which aren't implemented.

int RTPPacket::_extension [protected]

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.

int RTPPacket::_marker [protected]

The marker of this RTPPacket.

int RTPPacket::_padding [protected]

Set to 1 if padding is used in this RTPPacket, 0 otherwise. This implementation doesn't use padding bytes, so it is always 0.

int RTPPacket::_payloadType [protected]

The type of payload carried in this RTPPacket.

u_int16 RTPPacket::_sequenceNumber [protected]

The sequence number of this RTPPacket.

u_int32 RTPPacket::_ssrc [protected]

The ssrc identifier of the creator of this RTPPacket.

u_int32 RTPPacket::_timeStamp [protected]

The rtp time stamp of this RTPPacket.

int RTPPacket::_version [protected]

The rtp version of this RTPPacket.
