TLDR: existing Matroska files where elements such as the track language haven't been written need to be interpreted differently according to the new EBML RFC (before the RFC: track language missing means it's "eng"; after the RFC: missing means it isn't known). I've verified using the Wayback Machine[2] that right before the website was updated to match the released RFC the semantics of default values was as follows: > Default Values > > The default value of an element is assumed when not present in the data > stream. It is assumed only in the scope of its upper-element (for example > Language in the scope of the Track element). If the upper element is not > present or assumed, then the element cannot be assumed. Note that there is no distinction made for whether an element is mandatory or not. Now the RFC turns this into the following: > 6.1. Data Size Format > > =E2=80=A6 > If an Empty Element has a default value declared, then the EBML Reader > MUST interpret the value of the Empty Element as the default value. and > 11.1.6.4. minOccurs > > =E2=80=A6 > EBML Elements with "minOccurs" set to "1" that also have a default value > (see Section 11.1.6.8) declared are not REQUIRED to be stored but are > REQUIRED to be interpreted; see Section 11.1.19. and the whole section 11.1.19, which only talks about mandatory elements. So to recap: * Before the RFC all elements with default values would not have be written to the stream. * After the RFC non-mandatory elements are suddenly handled differently. This is not just theoretical. Pretty much all Matroska readers out there treat mandatory and non-mandatory elements the same wrt. default values. Most popular example is the track language element which is non-mandatory with a default value of `eng`. Software such as MKVToolNix, VLC, ffmpeg, mkclean all use the value `eng` if the element isn't present. In fact, our own published libEBML doesn't handle writing such elements like the RFC describes either; instead it handles them according to the old semantics. Here[3] is the issue I filed for it. The RFC retroactively changes the meaning of nearly all files ever created. No matter what we might think about how default values should be handled, such a radical, retroactive change is unacceptable in my opinion. Unfortunately I didn't realize this during the RFC process, so yeah, mea culpa =E2=80=94 I fucked this up, too. mkver remarked that this can be remedied somewhat by changing the Matroska specification for the affected elements and simply making them mandatory, thereby bringing their semantics back to what they were before the RFC. However, that won't work for frozen versions of the Matroska specs (v1=E2=80=933). Also: it is hella confusing for developers who were used to mandatory elements working one way for 18 years and now suddenly having to change their code. For example, here[4] is me getting confused about the new semantics in our recent discussion about the semantics of the new track header elements ('hearing impaired' flag etc.). On the flip side I cannot really think of an advantage of treating non-mandatory elements with default values differently than mandatory elements with default values. So=E2=80=A6 am I way off base here? Did I misunderstand the RFC and the sem= antics haven't actually changed? Did they change, and do we keep the semantics as they are now? How do we communicate the change to the wider developer community? If not: how would we go about fixing such an issue (probably by=E2=80=A6 do= ing another RFC obsoleting the existing one=E2=80=A6 this was my first RFC, not familiar with the right process)? I'm thankful for any kind of input & advice on this.

4. WG status update

   * draft-ietf-cellar-ffv1-19 was posted 2020-12-01,
       * in AD Followup, but there's still an open discuss position
   * draft-ietf-cellar-codec-05 was posted 2020-10-19
   * draft-ietf-cellar-matroska-06 was posted 2020-10-19
   * draft-ietf-cellar-tags-05 was posted 2020-10-19
   * has a FLAC specification been re-posted to the datatracker lately?
      https://datatracker.ietf.org/doc/draft-ietf-cellar-flac/
      Could use a new editor for this document.
      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=E2=80=99ll see if we want to meet at IE=
TF 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_whe=
n_played_on_computer_not/

9. FLAC issues
   * none other than lack of editor going forward

We can always change the order of things, but I moved FFV1=

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Codec Encoding for LossLess Archiving and Realtime transmission WG of the IETF.

        Title           : FFV1 Video Coding Format Version 0, 1, and 3
        Authors         : Michael Niedermayer
                          Dave Rice
                          Jerome Martinez
	Filename        : draft-ietf-cellar-ffv1-20.txt
	Pages           : 58
	Date            : 2021-02-23

Abstract:
   This document defines FFV1, a lossless intra-frame video encoding
   format.  FFV1 is designed to efficiently compress video data in a
   variety of pixel formats.  Compared to uncompressed video, FFV1
   offers storage compression, frame fixity, and self-description, which
   makes FFV1 useful as a preservation or intermediate video format.


The IETF datatracker status page for this draft is:
https://datatracker.ietf.org/doc/draft-ietf-cellar-ffv1/

There is also an HTML version available at:
https://www.ietf.org/archive/id/draft-ietf-cellar-ffv1-20.html

A diff from the previous version is available at:
https://www.ietf.org/rfcdiff?url2=draft-ietf-cellar-ffv1-20


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.

COMMENT:
----------------------------------------------------------------------

Thanks very much for having addressed all my comments, and special thanks for
the work in clearing up the meanings of things in Section 3.8.1.1.  I think I
do understand it now, and I think the work you've done in making that happen
has made this a better document.
