+1
As Jérôme already stated, the APV document starts with:

"**Perceptually** lossless video quality that is close to the original, 
uncompressed quality"


This is something fundamentally different than what FFV1 does, so I 
don't expect any conflicts with IETF's work on CELLAR.

Positively surprised (and very happy) to see it mentions the following:

   - "APV has been designed and developed to be made freely available to 
the industry for open public use without any licensing."

   - "The FFmpeg project is developing APV decoder [FFmpegAPVdec] and 
APV encdoer [FFmpegAPVenc] conformant to this document."

All the best!
