Package: kamoso
Version: 2.0.2-2+b1
Severity: wishlist
Dear Maintainer,
We would like to transition to qt-gstreamer 1.x and Kamoso is one of the users
of that package.
I've produced a patch that makes the qt4 version of kamoso compatible with qt-
gstreamer. I believe upstream is working on a qt5 version.
I haven't forwarded this patch upstream, however I'll point some of the KDE
developers to it to see if we should.
Diane.
