Closing the RTP Payload Format Media Types Registry
RFC 9751, “Closing the RTP Payload Format Media Types Registry”, is a Proposed Standard document published in March 2025 by M. Westerlund. It updates RFC 8088. The canonical text is published by the RFC Editor.
Abstract
The working group process and the authors of RTP payload formats have sometimes failed to ensure that the media types are registered in the IANA "RTP Payload Format Media Types" registry as recommended by RFC 8088. To simplify the process and rely only on the "Media Types" registry, this document closes the RTP payload- specific registry. In addition, it updates the instruction in RFC 8088 to reflect this change.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
