I guess the situation is grimmer than I imagined.

Specification and standardization is very important, which is why I've
been puzzled that people seem to be so willing to start from scratch
rather than use a spec that already works (like Quicktime).

It's very surprising that libmp4 would have that problem, since
libquicktime is listed as being under the LGPL and has a copy of it in
CVS. The FSF page says that the bare MPL is problematic, but a developer
can make an MPL project GPL friendly. I'm having a little trouble
finding libmp4; is it part of VideoLAN?
