The OpenH264 source code is BSD licensed and free software. But I have no
idea about the license of the binaries, and we definitely don't want
pre-built binaries.
Fedora probably will remove the functionality because they don't want
software to automatically download pre-built binaries, and because H.264 is
patented. [1]
For Trisquel, I think there are 2 solutions:
1) Integrate the (free) OpenH264 source code in Abrowser and remove the
automatic download functionality
2) Just remove the functionality and use gstreamer codecs as it already does.
