Hi all, An HTML5 presentation of today's IETF meeting on FFV1 and Matroska is available at http://recordings.conf.meetecho.com/Playout/watch.jsp?recording=IETF93_DISPATCH&chapter=chapter_2 <http://recordings.conf.meetecho.com/Playout/watch.jsp?recording=IETF93_DISPATCH&chapter=chapter_2>. The FFV1 and Matroska portion of the session is from ~9:00 - ~40:30 and open discussion starts at 14:40. At this point, for those who are interested in participating in further IETF discussions on this topic I encourage you to sign up on the IETF Dispatch mailing list at https://www.ietf.org/mailman/listinfo/dispatch <https://www.ietf.org/mailman/listinfo/dispatch>. Thanks much to those who joined the discussion via jabber and/or meetecho. At this point, we're very interested in comments, questions and feedback on this session and strategies for moving forward. One suggestion from Ted Hardy at ~31:00 that I found helpful was that the communities that develop the Matroska and FFV1 specifications should not s imply throw the specifications "over the wall" into IETF, but to move specification development itself to an IETF context in a way that brings our discussions currently in ffmpeg-devel and matroska-devel and integrates them into an IETF context.

Jerome Martinez pointed out that Matroska was used with VP8, VP9 > and WebM. Steve Lhome said that Matroska was designed for streaming in > networks and that Opus could be stored in Matroska for streaming. > Matroska is supported in Chrome, Firefox and MS Edge. > > Jerome Martinez said that, while the main purpose of Matroska was > storage, it could be used for transport and that they were looking for > transparency, open source and openness for their specification. They > didn't take it to SMPTE because it's paywalled. > > Tessa said that although the specifications are already available and > the work is complete, the specifications would benefit from the IETF > review process. Ben Campbell asked if it was ok if IETF take over change > control, and Tessa said that was understood. Ted Hardy said that the > community would need to participate in the IETF or the effort would > fail. Tessa said that she hoped the community and IETF would come > together. Steve Lhome, an original author of Matroska, said he would > continue to participate where ever the work was going to happen. > > Cullen and Dave Rice pointed out the needs for lossless video.
