Hi!

Thanks for the patch, I've put some comments inline below.

Looks like this is at the end of video.scm. That's OK, but often unwise
as if everyone adds new packages to the end of the modules, the patches
will often conflict. For that reason, it's normally helpful to add
packages not at the end, I usually add it close to related packages, or
those with a name close by in the alphabet.

So that someone looking at the package definition can tell why the tests
are disabled, it would be good to add a comment saying why. If it's that
the tests don't pass, then it can be a TODO comment.

I had a look at the few source files, and they suggested that this is
gpl2+, maybe there's a bit that's gpl2 only though?

Would you be able to send an updated patch?

Thanks,
