Solution 1
I had the same problem. After using below code it fixed.
sudo add-apt-repository ppa:mc3man/gstffmpeg-keep
sudo apt-get update
sudo apt-get install gstreamer0.10-ffmpeg
sudo apt-get install gstreamer0.10-plugins-ugly
Qt Creator 3.4.2 Ubuntu 14.04
Solution 2
I tried digging a little into this and according to this thread in the Qt forums the issue seems to be that the QtMultimedia module is still using GStreamer 0.10 as a backend - and from that it needs the gstreamer-0.10-ffmpeg
plugin which is not available in some distros anymore due to the move to libav.
If you're using a flavour of Ubuntu you can try installing gstreamer-0.10-ffmpeg
from Doug McMahon's ppa:
sudo add-apt-repository ppa:mc3man/gstffmpeg-keep
sudo apt-get update
sudo apt-get install gstreamer0.10-ffmpeg

I want to create a small mp3 player as a toy project so started with Qt for the GUI. When I try to play an mp3 file i get this error.
Warning: "No decoder available for type 'audio/mpeg, mpegversion=(int)1, mpegaudioversion=(int)1, layer=(int)3, rate=(int)44100, channels=(int)2, parsed=(boolean)true'." Error: "Your GStreamer installation is missing a plug-in."
I installed gstreamer and it's plugins after googling around
sudo apt-get install gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav
But I still get the error. How do I fix it?

Carlton about 7 yearsThere is now a Qt-specific library for GStreamer named, not surprisingly,
QtGStreamer
: gstreamer.freedesktop.org/data/doc/gstreamer/head/qt-gstreamer/…. It is available in the Ubuntu and Debian Jessie repositories under the nameqtgstreamer
