Video Frame Marking RTP Header Extension

Overview

RFC 9626, “Video Frame Marking RTP Header Extension”, is an Experimental document published in March 2025 by M. Zanaty, E. Berger, S. Nandakumar. The canonical text is published by the RFC Editor.

Abstract

This document describes a Video Frame Marking RTP header extension used to convey information about video frames that is critical for error recovery and packet forwarding in RTP middleboxes or network nodes. It is most useful when media is encrypted and essential when the middlebox or node has no access to the media decryption keys. It is also useful for codec-agnostic processing of encrypted or unencrypted media, while it also supports extensions for codec-specific information.
