The Trolltech exception clause 
(http://trolltech.com/products/qt/gplexception/) is only applying to future 
Qt releases as far as I know, so while it would be nice to have for 1.4.7, I 
don't think it would solve the issue totally there.

Well, it is described pretty well on 
http://gstreamer.freedesktop.org/documentation/licensing.html

basically, you have to decide on a license that allows the use of proprietary 
plugins. The easiest would be to add an exception, like suggested on that 
site I linked above. I would however not restrict it to gstreamer per se (but 
that is up to you to decide). 

As long as this exception is non-obligatory (that means, you allow the user of 
this code to remove the exception statement from his version before 
redistributing), and it thereby only grants additional rights and does not 
restrict any of the rights GPL grants you (as a copyright holder), it is 
trivially and fully GPL compatible.
