FFmpeg and the GPL

Four pages need FFmpeg, because no browser can open AVI or FLV on its own. FFmpeg is free software under the GNU General Public License, and it is served from this site rather than a third party — which means this site distributes it, and must offer its source. It does, below. The part of our own code that drives FFmpeg is published under the same licence; the rest of the site does not touch it.
