Well kinda, but since the GStreamer project aims at becoming a systems
library we feel we need to allow all kind of programs linking to us even
programs licensed under non-GPL compatible licenses.

The difference is that when you link against the GPL it demands that
your code is licensed under the GPL or a license that allows it to be
re-licensed under the GPL. The LGPL on the other hand puts no demands on
the programs linking to the LGPL code, but it do demand that all code
changes to the LGPL code itself are submitted back and licensed under
the LGPL too.

I will, but I also need your approval since the codebase contains both
yours and his code now.

Thanks we are working hard at making it an excellent plattform to build
all kinds of multimedia applications. In fact we have been chosen
already to be the multimedia foundation for GNOME 2.2.
