Can't play mp3 files. Missing ID3 Tag Demuxer

quodlibet refuses to play my .mp3 files with the following error:

No Gstreamer element found to handle media format. Media format: ID3 tag demuxer

gstreamer is already installed on my system, so clearly, some other plugin or codecs are required for this to work. There are quite a few plugins on the aur when I did a quick search: yay -Ss gstreamer

Which one should I install? And why isn’t the required plugins inside the main repo?

UPDATE:
According to this page (https://gstreamer.freedesktop.org/documentation/id3demux/index.html?gi-language=c#id3demux), I probably need to install the id3demux plugin, which can be found in the gstreamer-good-plugins package. However, the good-plugins package in the aur is for gstreamer0.10 whereas the gstreamer in the main repo is version 1.20.3-2

How about:

$  pacman -Ss gst-plugins-good
extra/gst-plugins-good 1.20.3-2 
    Multimedia graph framework - good plugins

?

$ pacman -Si quodlibet

@pebcak Yeah. That did the trick. I was still googling for alternative names for the package when your answer came through. I tried pacman -Ss good-plugins but stopped trying when the search came up empty. Damn. I should’ve tried to swap the word ordering, and perhaps go through quodlibet’s package description. :roll_eyes: I’m not proud of myself.

Thanks, though.
