just a quick reply now, a longer one later.

No, there is no easy quick way to get an agreement with "ffmpeg" as legally
there is no entity that can represent all copyright holders. You would have
to negotiate with all individual contributors, sorry!

The best advice I can give you is to offer some money for the pot for the
relicensing (that might make it more likely that it happens) and wait for
my next posting regarding that topic on the ffmpeg-devel list. I haven't
had time in the past few days to compile what the current status is and
write about options that exist as I wanted to do that thoroughly.

Best regards,
