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.

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.

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.

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.

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)
