Subject: Make KSCD play audio CDs with gstreamer backend From: upstream Signed-Off-By: Lubos Lunak Bug: 588230 Patch-upstream: yes commit 67f58d71d5b27e5a15a8e88eff1b3b26628ae37f Author: Jens Bache-Wiig <jbache@trolltech.com> Date: Thu Mar 19 11:18:16 2009 +0000 Phonon/Gstreamer: Add support for audio CD tracks through the MediaController interface. This patch adds basic support for cdda to the GStreamer backend. It's still somewhat limited by the limited autodetection of CD media but should be enough to make KSCD work with GStreamer. diff --git a/gstreamer/mediaobject.cpp b/gstreamer/mediaobject.cpp index 5398f0c..74fc1b4 100644 --- a/gstreamer/mediaobject.cpp +++ b/gstreamer/mediaobject.cpp @@ -14,7 +14,6 @@ You should have received a copy of the GNU Lesser General Public License along with this library.
