Rather than drafting the ffv1 specification within the current github space at https://github.com/FFmpeg/FFV1, would it make more sense to develop ffv1's specification within the libav/ffmpeg projects themselves (such as in http://git.libav.org/?p=libav.git;a=tree;f=doc and http://git.videolan.org/?p=ffmpeg.git;a=tree;f=doc)?

The official FFv1 spec is in lyx format at https://github.com/FFmpeg/FFV1
its also available as html, txt, pdf and can trivially be converted
to pretty much any other format one might want.

If someone, luca? wants to improve it in some way, its very easy to
clone the git repo on github and change it to their hearts desire.
Then just send me a pull request and ill make sure the changes get
reviewed and integrated. The official FFv1 spec is actively
maintained by me.

about the suggestion of moving it to a wiki, i belive a wiki is a
poor choice for a specification as a specification must be correct and
a wiki allows too broad and unchecked editing. We wouldnt want someone
reword text in it that she might find hard to understand but that
after the rewording then turns out to have totally different meaning
and resulting in incompatible implementations.

about submiting it to a standards body, i think thats a great idea but
we first should finish 1.3, converting the spec for this to the needed
format seems a minor technicallity to me but maybe iam missing

Either way, i see it with great concern that libav started writing a
ffv1 spec in their doc directory and has already introduced changes
to ffv1 without any kind of discussion on the nut mailing list.
seeing that and then seeing libav developers contact you in private
about moving the spec to a different place and format. Iam not sure
what i should be thinking about that.
