Description of problem:
qtconfig-qt4 (qt-config subpackage) has a tab for Phonon configuration, allowing to configure the Phonon GStreamer 0.10 backend. This also depends directly on GStreamer 0.10, to enumerate audio sinks and video rendering modes. With phonon-backend-gstreamer having switched to GStreamer 1, this tab is obsolete.
The easiest solution is to build qtconfig-qt4 without Phonon support. There is no port to GStreamer 1 available, and there is unlikely to ever be one because upstream dropped support for qtconfig in Qt 5 (see https://bugreports.qt-project.org/browse/QTBUG-32250).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. repoquery --repoid=rawhide --requires qt-config
Contains GStreamer 0.10 libraries:
Does not contain those libraries.
This is basically the opposite of the old bug #503260.
I'm taking this (building Qt without the bundled Phonon entirely, which gets us rid of the GStreamer 0.10 use in qtconfig-qt4, on F21+ and adding phonon.prl to phonon-devel where it belongs).
I built Qt without Phonon in Rawhide. We need to check whether QMake-based stuff using QT+=phonon still works, and if not, what needs to be changed (e.g., do we need to add libphonon.prl to phonon-devel? I now think it might actually not be needed).
qt-4.8.6-11 landed for awhile, closing.
