            Bug ID: 794298
           Summary: Cannot inspect pad templates in GJS
    Classification: Platform
           Product: GStreamer
           Version: 1.12.x
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: don't know

     GNOME version: ---

I'm trying to sketch a pipeline editor using GJS, but I'm hitting what seems to
be a binding issue. I've isolated a simple test below:


const Lang = imports.lang;
const Gst = imports.gi.Gst;

Gst.init(null);
let registry = Gst.Registry.get();
let elementFeatureList = registry.get_feature_list(Gst.ElementFactory);
elementFeatureList.forEach(Lang.bind(this, function(factory) {
            let padTemplates = factory.get_static_pad_templates();
        }));


This is giving the following error:

Gjs-WARNING **: JS ERROR: Error: Can't create a Javascript object for
StaticPadTemplate; no way to copy


Am I missing something? Thanks for your efforts!
