Thanks. Don't worry, I am not interested in contributing my AGPL component
to FFMpeg.
Nor am I interested in forking FFMpeg.

But, I would like to find a way of distributing FFMPeg with my codec,
so users can take advantage of it if they are interested.
This codec will be significantly faster than any other open source codec.

Thanks. I'm afraid I have my hands full with my own library :)

Personally, I would recommend switching over to OpenJPEG:
BSD 2 license, ISO reference implementation for standard,
and large test suite. Rather than spending time on your native codec.
Just my 2 cents.  Codec development requires an enormous amount of time
and expertise to get right.

Kind Regards,
