I’m on CentOS 7. Gstreamer plugin packages are installed. I am getting the following error when I try to play music from the web interface:

```
    WARNING Could not find a MPEG-1 Layer 3 (MP3) decoder to handle media.
INFO You might be able to fix this by running: gst-installer "gstreamer|0.10|mopidy|MPEG-1 Layer 3 (MP3) decoder|decoder-audio/mpeg, mpegversion=(int)1, layer=(int)3, parsed=(boolean)true"
WARNING There is no codec present that can handle the stream's type.
ERROR Your GStreamer installation is missing a plug-in.
ERROR Resource not found.

```

There is no gst-installer package. What should I install?

Fixed it by upgrading pafy:

```
sudo pip2 install -U pafy
