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.

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
