Hi cellar,

I uploaded a new draft of draft-ietf-cellar-ffv1 to the document tracker at https://datatracker.ietf.org/doc/draft-ietf-cellar-ffv1/. I also submitted a draft of a new document called draft-ietf-cellar-ffv1-v4 for approval from the chairs (once approved it should be listed in https://datatracker.ietf.org/wg/cellar/documents/ as “FFV1 Version 4”). This is the first version of the FFV1 drafts where the documentation for FFV1 versions 0, 1, and 3 and the documentation for FFV1 version 4 (under progress) are documented in separate drafts in alignment of the charter’s milestones.

Since the last version, the updates for the FFV1 documents include:
- using one markdown file to ‘make’ separate FFV1 v0-1-3 and FFV1 v4 drafts https://github.com/FFmpeg/FFV1/commit/f16f9e1b1daafa9208db94496a84b9a1ecd9068e
- more explicate notes about temporary variables in the pseudo-code https://github.com/FFmpeg/FFV1/commit/18375b0a3ea13ffe4f28d8dff0bf5d2455b8ec3c
- optimized ceiling function https://github.com/FFmpeg/FFV1/commit/4428eadae643aa791d9d8af73262237c38e611a6
- limiting a JPEG2000-RCT exception to non-alpha frames https://github.com/FFmpeg/FFV1/commit/4d370166448b1a33c6485165d6cd0b96c2d08ea2
- initial draft of IANA considerations https://github.com/FFmpeg/FFV1/commit/4b664e7878368996588fe97e53edb96d811378db
- correction to chroma subsampling references https://github.com/FFmpeg/FFV1/commit/4ead3896beb3ddc9c47c85c663998682afcdb49f
- local definition of Container https://github.com/FFmpeg/FFV1/commit/e7d3abbed785ce8fc03555f87c2b9a5d4259deee
- other updates for grammar, inter-sectional linking, backtick quoting

Notes to chairs:

The milestone section refers to FFV1 documents like this:

> Jul 2017	Submit specification for FFV1 video codec version 4 to IESG (Standards Track)
[…]
>Apr 2017	Submit informational specification for FFV1 video codec versions 0, 1 and 3 to IESG for publication
> draft-niedermayer-cellar-ffv1

The reference to draft-niedermayer-cellar-ffv1 SHOULD be updated to draft-ietf-cellar-ffv1since this is now a working group document. Also obviously the dates should be updated.

Best Regards,
Dave Rice
