Unable to build 2.2.4 due to mime_types#get type mismatch

Trying to build liquidsoap for packaging the new version into Debian I get the following error

File "src/core/decoder/gstreamer_decoder.ml", line 314, characters 37-51:

Hi @paddatrapper,
Try building without gstreamer.

Thanks!

I would strongly suggest shipping a package without gstreamer. Its architecture is designed for GUI application and is causing issues such as random freeze at shutdown and all its functionalities are now deprecated in favor of ffmpeg.

How do I actually disable gstreamer? Not providing the gstreamer dependency seems no longer to be enough, as it still fails at the same point

@paddatrapper, maybe I am missing something and @toots knows better, but may I review the build config and build log?
Also #3769.

If you don't have the gstreamer opam package installed, liquidsoap should not build with gstreamer.
