6. Use with the Extended RTP Profile for RTCP-based Feedback

This section gives general hints for the usage of this payload format with the extended RTP profile for RTCP-based feedback, denoted AVPF [1]. Note that the general RTCP send and receive rules and the RTCP packet format as specified in RTP apply, except for the changes that the AVPF profile introduces. In short, the AVPF profile relaxes the RTCP timing rules and specifies additional general-purpose RTCP feedback messages. See [1] for details.
