RFC 5045 is included in the list of RTP header extensions in Section 9.14, even though it isn't mentioned in RTP usage. Was this a mistake? Also RFC 6051 is not included in the list of header extensions, although it is mentioned in RTP-Usage Section 5.2.1: 5.2.1. Rapid Synchronisation Many RTP sessions require synchronisation between audio, video, and other content. This synchronisation is performed by receivers, using information contained in RTCP SR packets, as described in the RTP specification [RFC3550]. This basic mechanism can be slow, however, so it is RECOMMENDED that the rapid RTP synchronisation extensions described in [RFC6051] be implemented in addition to RTCP SR-based synchronisation. The rapid synchronisation extensions use the general RTP header extension mechanism [RFC5285], which requires signalling, but are otherwise backwards compatible. Proposed change is to add RFC 6051 to the list of header extensions and remove RFC 5045.
