Terje, did you see the email on November 25 from Andrea titled "Formats and Codecs in CinGG"? There was an attached formats.txt file there too.

The AVC profile names and the first table lines could be a sample for
furher documentation:

This table is VERY complicated and would require a lot of effort and probably get quickly outdated. But it sure looks nice!
