RTCP_SDES_Packet Class Reference

The Source Description packet is sent by all members of a session. At a minimum, the canonical name (or CNAME) is sent with each RTCP packet. Other items such as name, email, or location are included less frequently. More...

Detailed Description

The Source Description packet is sent by all members of a session. At a minimum, the canonical name (or CNAME) is sent with each RTCP packet. Other items such as name, email, or location are included less frequently.


Constructor & Destructor Documentation

RTCP_SDES_Packet::RTCP_SDES_Packet char *  buffer,
int *  len
 

Constructor for incoming SDES packets.

RTCP_SDES_Packet::RTCP_SDES_Packet void   ) 
 

Constructor for outgoing SDES packets.

RTCP_SDES_Packet::~RTCP_SDES_Packet void   )  [virtual]
 

Destructor.


Member Function Documentation

void RTCP_SDES_Packet::add_chunk ACE_UINT32  ssrc  )  [private]
 

Add a chunk to the packet.

void RTCP_SDES_Packet::add_item ACE_UINT32  ssrc,
unsigned char  type,
unsigned char  length,
const char *  data
 

This will add a standard item of type and length for the ssrc specified. When the first item for a ssrc is added, a chunk is created. Subsequent items for that ssrc are added to the same chunk. New chunks are created for each unique ssrc.

void RTCP_SDES_Packet::add_priv_item ACE_UINT32  ssrc,
unsigned char  nameLength,
const char *  name,
unsigned char  dataLength,
const char *  data
 

This will add a private item using the name and data for the ssrc specified. When the first item for a ssrc is added, a chunk is created. Subsequent items for that ssrc are added to the same chunk. New chunks are created for each unique ssrc.

void RTCP_SDES_Packet::build_packet void   )  [private, virtual]
 

Used to create the byte representation of the RTCP packet.

Implements RTCP_Packet.

void RTCP_SDES_Packet::dump void   ) 
 

Prints the contents of the packet.

unsigned int RTCP_SDES_Packet::packet_size void   )  [virtual]
 

Returns the size of the packet in bytes.

Implements RTCP_Packet.

ACE_UINT32 RTCP_SDES_Packet::ssrc void   )  [inline]
 

This returns the synchronization source id for this packet. This assumes that this source is only receiving messages from end systems (i.e. only one source id per SDES)


Member Data Documentation

sdesChunk_t* RTCP_SDES_Packet::chunk_ [private]
 

A linked list of chunks for this packet (only 1 for non-mixers).

unsigned long RTCP_SDES_Packet::num_chunks_ [private]
 

The number of chunks contained in this packet. 1 for end systems, 1+ for mixers
