X-List-Received-Date: Mon, 13 Mar 2017 22:31:03 -0000 A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Audio/Video Transport Payloads of the IETF. Title : RTP Payload Format for VP9 Video Authors : Justin Uberti Stefan Holmer Magnus Flodman Jonathan Lennox Danny Hong Filename : draft-ietf-payload-vp9-03.txt Pages : 20 Date : 2017-03-13 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. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-payload-vp9/ There's also a htmlized version available at: https://tools.ietf.org/html/draft-ietf-payload-vp9-03 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-payload-vp9-03 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

This draft is a work item of the Audio/Video Transport Payloads of the IETF. Title : RTP Payload Format for Flexible Forward Error Correction (FEC) Authors : Varun Singh Ali Begen Mo Zanaty Giridhar Mandyam Filename : draft-ietf-payload-flexible-fec-scheme-04.txt Pages : 38 Date : 2017-03-28 Abstract: This document defines new RTP payload formats for the Forward Error Correction (FEC) packets that are generated by the non-interleaved and interleaved parity codes from a source media encapsulated in RTP. These parity codes are systematic codes, where a number of repair symbols are generated from a set of source symbols. These repair symbols are sent in a repair flow separate from the source flow that carries the source symbols. The non-interleaved and interleaved parity codes which are defined in this specification offer a good protection against random and bursty packet losses, respectively, at a cost of decent complexity. Moreover, alternate FEC codes may be used with the payload formats presented. The RTP payload formats that are defined in this document address the scalability issues experienced with the earlier specifications including RFC 2733, RFC 5109 and SMPTE 2022-1, and offer several improvements. Due to these changes, the new payload formats are not backward compatible with the earlier specifications, but endpoints that do not implement the scheme can still work by simply ignoring the FEC packets. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-payload-flexible-fec-scheme/ There are also htmlized versions available at: https://tools.ietf.org/html/draft-ietf-payload-flexible-fec-scheme-04 https://datatracker.ietf.org/doc/html/draft-ietf-payload-flexible-fec-scheme-04 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-payload-flexible-fec-scheme-04 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

I don't want to hold this up very long, but giving the WG a week to look at this is fine. So please provide any feedback by 5th of April. This inline diff gives you indications of the changes that has been introduced by me and the RFC-editor in response to my answers to open issues. https://www.rfc-editor.org/authors/rfc8088-lastdiff.html I would especially like to point out are: - I have changed from "media stream" to "RTP Stream" definition to align with RFC 7656 (Taxonomy) definition. - Section 3.3.3: Removal of the paragraph referencing the RTP multiplexing guidelines. - Section 4.1.1: Clarifications on authors responsible for judging when to request WGLC. - Section 8: Note about authoring tools. - A.11.1: Recommendation that MacOS type is not needed and removed reference as the reference has disappeared.

This change, due to the placement of the field bits, indirectly adds a requirement that all ANC packets within a RTP frame is from the same video field, as it is not possible to specify the field bits per ANC packet. This was not a requirement earlier, and for interlaced the field polarity could be discovered from the Line_Number field. I believe this should at least be clarified in the RFC that it is now requi= red that all ANC packets in a RTP frame are from the same video field.

Payload WG status update - Chairs

RTP Howto:

The draft-ietf-payload-rtp-howto-14 is in AUTH48, bu= t has been with the IESG for 3 years and Magnus informed that there will be= a few (editorial) changes due to things that changed during that time, lik= e references and the new RFC format.

The changes will be sent to Payload mailing list for= review.

VP9 Payload:

Jonathan informed that some interest was expressed t= o make the VP9 payload format work with multicast (streaming). This would r= equire support for MRMT [RFC 7656] in the VP9 payload draft, not only SRST = that is the case today. It is not clear if that use case would require use of RTP, though.

Since the VP9 section will be taken out from the fle= xible FEC draft (see later), the support for FEC will be in the VP9 Payload= .

Tomas Edwards volunteered to review the draf= t-ietf-payload-rtp-vc2hq draft.

Specified order of FEC and SRTP – RFC3711 FEC = before SRTP while for PERC recommends FEC after SRTP.

What follows is a list of questions that did not have immediately obvious answers from the text in the draft, as well as a few other minor issues we noticed. These may not be immediately comprehensible to people who weren't involved in the conversation (or haven't read the draft), but to the extent that they are we thought it better to share with the list. 1. What is a frame? 2. What is a picture? It's a super frame (probably). 3. Super frame means something else in the VP9 specification. 4. N_G indicates the numer of "frames"? What kind of frame? It's a super frame (probably). 5. GOF is a group of "Pictures", but not a GOP (it doesn't start with a keyframe). 6. Payload type != TP 7. P: should explicitly say it can still use inter-layer prediction. 8. Is a frame allowed to have zero references but not be a keyframe? According to the VP9 Specification, yes (but only if show_frame == 0), but the draft does not have any way to represent this. 9. Someone should write down what "dependency" means and describe how probabilities work. 10. In order to describe how "dependencies" work, need to document the limitations on how the following fields must be set inside the VP9 payload itself: show_frame frame_type intra_only error_resilient_mode refresh_frame_idx refresh_frame_flags refresh_frame_context reset_frame_context 11. Should provide an example of how to set up the dependencies for a set of spatial and temporal layers (including how to set things like frame_context_idx inside VP9). 12. "the T bit (described below) MUST also be set to 0..." but the T field is 2 bits wide. 13. Is temporal layer 0 the base layer? (this can kind of be inferred from "For the base layer frame with S equal to 0..." but that's spatial not temporal, and should probably be explicit for both) 14. What is a key picture? 15. While a VP9 frame can only have three reference frames, it can have a frame_context_idx that refers to a set of probabilities that came from a frame different from any of those three frames. So it may actually "depend" on four frames, which as written this draft cannot represent.
