                   RTP Payload Format for H.264 Video

Abstract

   This memo describes an RTP Payload format for the ITU-T
   Recommendation H.264 video codec and the technically identical
   ISO/IEC International Standard 14496-10 video codec, excluding the
   Scalable Video Coding (SVC) extension and the Multiview Video Coding
   extension, for which the RTP payload formats are defined elsewhere.
   The RTP payload format allows for packetization of one or more
   Network Abstraction Layer Units (NALUs), produced by an H.264 video
   encoder, in each RTP payload.  The payload format has wide
   applicability, as it supports applications from simple low bitrate
   conversational usage, to Internet video streaming with interleaved
   transmission, to high bitrate video-on-demand.

   This memo obsoletes RFC 3984.  Changes from RFC 3984 are summarized
   in Section 14.  Issues on backward compatibility to RFC 3984 are
   discussed in Section 15.
