Then I see (once): (gst-play-1.0:20950): GStreamer-WARNING **: 13:02:08.182: 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. And it still selects pulsesink.
