Ah you found out how it works! Nice!

Yes. I found some examples that includes adding custom callback for
subroutines that might be helpful:

Well, it is an image file so i don't think there should be a "source" for it :)

The file is used for the website (e.g. http://ffmpeg.org/ffmpeg.html),
but I guess it's not needed.

Also yes, the license of the file is not clear. We lost contact with
the author of the logo, Hervé Flores, and it was not explicitly
released under a free license. However he did "provide us with
sufficient rights to use the art in any form: not limited to the web
site, t-shirts, and print media; to refer only to the FFmpeg project
at no cost to us" ( from

Another problem with your approach is that @float is not handled
correctly. It is also a good idea to support both texi2html and
makeinfo for now as makeinfo doesn't look as stable as texi2html.
