Do the contributors know they are covered by NoteWell. Spencer to check contribution file, check that this is in our weekly summary, etc. Maybe Florian Weimer! * We agreed at the December meeting that we would have a focused conversation about FFV1 v4 in our February meeting, and noted then that the April 2021 date is not realistic. 5. 2021 virtual interim meeting dates * Please note that the proposed 2021 dates discussed at our previous meeting are now official, approved by our AD, and listed at https://datatracker.ietf.org/wg/cellar/meetings/ * Sometime around 2021-09-28, we’ll see if we want to meet at IETF 112 on November 6-12, 2021, in person in Madrid. 6. remaining FFV1 issues from DISCUSS * IESG ballot positions at https://datatracker.ietf.org/doc/draft-ietf-cellar-ffv1/ballot/ * Have we closed on Barry's concerns about section 3.8.1.x? Not quite yet - we just need to rewrite this section into text, rather than explaining the bespoke notation we're using. * Any remaining comments from any ADs that still need to be addressed? * If all of the above, what needs to happen to submit an updated draft? Jerome, Michael and DR will organize a time to redo the 3.8.1 formula into more clear pseudo-code. 7. From private e-mail to Spencer, now forwarded to the mailing list: "What is the canonical procedure to create an "infinite" audio stream, using ~~Opus and~~ FLAC codecs?" I have been attempting to locate a site which streams Opus continuously to test. I also am interested in the exact opusenc, et al. commands necessary to achieve creation of live audio streams. The use cases are implementation of user-defined Web radio station, the capability to play the "infinite" stream using HTMLAudioElement (WHATWG/HTML) over HTTP. ("infinite" is quoted here as there is no way to verify infinity; the gist is playback should not stop; is not seekable). * 8. Matroska issues * PR #447 has been under a lot of discussion in Github. We're ready to merge this PR. * We're working on code now, so not a lot of changes to the spec this month. * issue about negative delay in ... ? https://www.reddit.com/r/mkvtoolnix/comments/l4uh6z/audio_delay_working_when_played_on_computer_not/ 9. FLAC issues * none other than lack of editor going forward * https://github.com/ietf-wg-cellar/Cellar-FLAC * AOB? NEXT MEETING February 23, 2021.
