commit b85e8c187b4eabf9765bc05348f6232ba32c9493
Author: Andreas Cord-Landwehr <cordlandwehr@kde.org>
Date: Fri Aug 29 16:51:30 2014 +0200
Porting to GStreamer-1.0 API and QtGStreamer-1.2
This is the first iteration of a porting patch to upgrade Kamoso to work with GStreamer-1.x (in particular, 0.10 is deprecated and unmaintained by upstream). The patch in its current version does the following:
* update the cmake find module to find the new version of gstreamer and qtgstreamer
* fixes compilation with the new version
I am quite sure that further changes at the pipelines are necessary to make it work at runtime, yet an area where I do not have much experience (hence, all these people you get the review request :)
In the big picture, I would like to have Kamoso ported asap, since with Artikulate a first KDE application switched to the new QtGStreamer version and the continiuous integration system can only support one qtgstreamer version for all. Also, it would be good to have all KDE applications ready for QtGStreamer-1.2 with the KDE SC 4.14 release to allow distros to upgrade all in one step.
