Title: Using Codec Control Messages in
the RTP Audio-Visual Profile with Feedback
with Layered Codecs

DOI: 10.17487/RFC8082
This document updates RFC 5104 by fixing a shortcoming in the
specification language of the Codec Control Message Full Intra
Request (FIR) description when using it with layered codecs. In
particular, a decoder refresh point needs to be sent by a media
sender when a FIR is received on any layer of the layered bitstream,
regardless of whether those layers are being sent in a single or in
multiple RTP flows. The other payload-specific feedback messages
defined in RFC 5104 and RFC 4585 (which was updated by RFC 5506) have
also been analyzed, and no corresponding shortcomings have been
found.
This document is a product of the Audio/Video Transport Extensions Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
