(WPEWebProcess:780747): GStreamer-WARNING **: 16:13:57.144: External plugin loader failed. This most likely means that the plugin loader helper binary was not found or could not be run. You might need to set the GST_PLUGIN_SCANNER environment variable if your setup is unusual. This should normally not be required though.
