Missing Gstreamer plugin for m4a

Hi. I’m trying to play a podcast in m4a format and I’m getting this error.

2017-01-25 17:09:45,653 WARNING [673:MainThread] mopidy.audio.actor: Could not find a MPEG-4 AAC decoder to handle media.

Any idea which plugin I need to install?



Do you have gstreamer1.0-plugins-{good,bad,ugly} ?

I just tried installing good, which is why it doesn’t say “automatic”, presumably.

So, no, you don’t. Installing gstreamer1.0-plugins-bad should be the solution.


apt-get install gstreamer1.0-plugins-bad

Sorted. Thanks. :slight_smile:

Hello all,

Iam running mopidy on my osmc installation. I have installed all gstreamer plugins but still I get the message “Gstreamer fehlt ein Plugin” bei m4a files.

What can I do?


What’s the actual error message? Is it the same as I posted?

Oh shit,

now I realized that mopidy 0.19 was installed however. After adding the correct repository now everthing works fine with mopidy 2.1.0
