                    RTP Payload Format for VP9 Video
                       draft-ietf-payload-vp9-04

Abstract

   This memo describes an RTP payload format for the VP9 video codec.
   The payload format has wide applicability, as it supports
   applications from low bit-rate peer-to-peer usage, to high bit-rate
   video conferences.  It includes provisions for temporal and spatial
   scalability.
