Logistics for Meeting. 2a) Etherpad for notes https://etherpad.tools.ietf.org/p/notes-cellar-virtual01?useMonospaceFont=true 2b) Roll call Dave Rice did makefiles and markdown. Jerome Martinez focused on ffv1 document (both version) Martin Below worked on Matroska, chaptering, and tags. Moritz Bunkus author of MKVToolNix, transposing from container to container, more than codec. Reto Kromer help on Matroska and review work. 3. Status of draft-ietf-cellar-ebml-04 document. - Is it ready? - Open Issue: #48 NEED Proposed Text add section for handling bad data https://github.com/Matroska-Org/ebml-specification/issues/48 - Open Issue: #157 NEED Proposed Text. Define DoctypeVersion 0 as invalid/experimental https://github.com/Matroska-Org/ebml-specification/issues/157 AGREE to do this? DR: if we had a version 0, then there would be no valid attributes, so we'd have to make exceptions. so just define it as invalid. Seems like consensus. DR: I can offer to add a pull request to say that DocType version MUST be 1 of higher, currently only docType=1 is defined. - split the question of experimental element IDs from issue of DoctypeVersion. - General topic of Security Considerations section (which is now part of the draft) - Do we need to define a maximum nesting depth? - Should VINT be canonically the shortest representation possible? - Need to add IANA registry for EBML binary tag names What is the amenda formula? (MCR will propose IANA considerations text to list) https://www.ietf.org/mail-archive/web/cellar/current/msg01269.html 4. Status of draft-ietf-cellar-ffv1-02 (version 0,1,3) -- legacy format. - Is this two documents from one source really working for everyone? - should we just fork repo? - DR: I think the two documents work well, it was suggested by Niedermayer. - Can we publish this document without waiting for -v4? - RK: yes - Need to change this to Informational: Discussion. Action: Need Michael Niedermayer to merge document, Dave Rice to send pull request changing document status (this change is to change from std to info and to increment the version). 5. Status of draft-ietf-cellar-ffv1-v4-00 - This version is IETF Standards Track. - what documents depend upon this document? No documents depend on this. This document repeats text from draft-ietf-cellar-ffv1 (informational), so should be published afterwards, but has no direct normative reference to it General question on normative references to web pages: Suggest asking rfc-editor@rfc-editor.org for suggestions on what to do about pages you're particularly worried about being changed. See also: RFC 7322 Section 4.8.6.1 6. Status of draft-lhomme-cellar-codec-00 MB: has some comments. WG adoption? 7. Status of draft-lhomme-cellar-matroska-04 WG adoption, can it proceed without ffv1-v4? Yes, these only reference versions 0, 1, and 3 for now. 8. Status of draft-lhomme-cellar-tags-00 WG adoption, can it proceed without ffv1-v4? Yes, these only reference versions 0, 1, and 3 for now. Will send out calls to adopt these three documents as working group documents to the list. 9. Importance of chapters/tags? May prefer to split into separate document because of complexity and timeline to resolve all issues
