Well, I think providing modified ffmpeg's sources is not a question at all, that
is stated explicitly. But as far as I understood the previous author, he claims
that the whole code should be GPLed (i.e. should be open) - I mean that GUI or
whatever that SUPER codec provides. I'm not really sure if that is the case
actually, that's why I followed this topic :)
