Structure defining an RTCP session. More...
Detailed Description
Structure defining an RTCP session.
The concept "RTCP session" is not defined in RFC 3550, but since this structure is analogous to ast_rtp, which tracks a RTP session, it is logical to think of this as a RTCP session.
RTCP packet is defined on page 9 of RFC 3550.
