Dear cellar,
https://datatracker.ietf.org/doc/draft-ietf-cellar-ffv1/ <https://datatracker.ietf.org/doc/draft-ietf-cellar-ffv1/>

Version -00 of draft-ietf-cellar-ffv1 was published on Monday. Note that the prior versions were made before this document gained WG Doc status, so the prior versions are at https://datatracker.ietf.org/doc/draft-niedermayer-cellar-ffv1/ <https://datatracker.ietf.org/doc/draft-niedermayer-cellar-ffv1/>. The recent updates in this new version are detailed in the commits from May 16 - July 2 at https://github.com/FFmpeg/FFV1/commits/draft-ietf-cellar-00 <https://github.com/FFmpeg/FFV1/commits/draft-ietf-cellar-00>. In summary the update includes:

- local acknowledge/description of the pseudo-code used to define the structure of the bitstream
- clarifications to language description Content, functions, median prediction
- a summary of the versions of FFV1 defined by the document
- adjustments to vocabulary and descriptions of Quantization Table sets, Quantization Tables, Quantization Sample Differences

At this point there are only 3 open issues in the github tracker for FFV1. 2 pertain to enhancements for consideration of the subsequent version of FFV1. And the other is a small issue regarding locally defining the use of len_count in the pseodo-code.

The document could use some reviews to determine what other work may be considered here, if any.

Best Regards,
Dave Rice
