Ofer Idan, Roni Even · 2018
This document updates the Frame Marking RTP header extension in draft- ietf-avtext-framemarking-06 used to convey information about video frames that is critical for error recovery and packet forwarding in RTP middle-boxes or network nodes. The flags for frame marking for non-scalable streams include the D bit to mark a frame that can be discarded, and still provide a decodable media stream. There is also the I bit for frames that can be decoded independent of prior frames, e.g. intra-frame. This memo adds priority values for the non-scalable streams discardable frames
