RTCP_SDES_Packet (char *buffer, int *len) | |
Constructor for incoming SDES packets. | |
RTCP_SDES_Packet (void) | |
Constructor for outgoing SDES packets. | |
virtual | ~RTCP_SDES_Packet (void) |
Destructor. | |
void | add_item (ACE_UINT32 ssrc, unsigned char type, unsigned char length, const char *data) |
void | add_priv_item (ACE_UINT32 ssrc, unsigned char nameLength, const char *name, unsigned char dataLength, const char *data) |
unsigned int | packet_size (void) |
Returns the size of the packet in bytes. | |
void | dump (void) |
Prints the contents of the packet. | |
ACE_UINT32 | ssrc (void) |
Private Member Functions | |
void | build_packet (void) |
Used to create the byte representation of the RTCP packet. | |
void | add_chunk (ACE_UINT32 ssrc) |
Add a chunk to the packet. | |
Private Attributes | |
unsigned long | num_chunks_ |
sdesChunk_t * | chunk_ |
A linked list of chunks for this packet (only 1 for non-mixers). |
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.
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] |
void RTCP_SDES_Packet::dump | ( | void | ) |
Prints the contents of the packet.
unsigned int RTCP_SDES_Packet::packet_size | ( | void | ) | [virtual] |
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)
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
