This update reflects the WG decisions from the January virtual interim meeting. A new section on VP9 was added (which was originally present but removed in version -05 per WG decisions at that time, so we have come full circle). The VP9 section clarifies how to map the VP9 P and U bits to the frame marking I and B bits, which was a point of confusion for one implementer.

Regards,
Mo

Abstract:
   This document describes a 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.
