Hi Ott,

Thanks for the lead. I tried pinning gstreamer and gst-plugins-base to
older versions available in Guix, and removing gst-plugins-base from
being an input to OBS (though I'm not positive this removes it from all
recursive inputs), but I'm still having the issue :(

Here is what I have so far:

(let ((parent (specification->package "obs")))
  (package
   (inherit parent)
   (inputs (modify-inputs (package-inputs parent)
                          (replace "gstreamer"
                                   ((options->transformation '((with-version . 
"gstreamer=1.20.3")))
                                    (specification->package "gstreamer")))
                          (replace "gst-plugins-base"
                                   ((options->transformation '((with-version . 
"gst-plugins-base=1.20.3")))
                                    (specification->package 
"gst-plugins-base")))))))

Also tried with (remove "gst-plugins-base") instead of the replace.
