Basically we are discovering a file which in turn leads to ffmpeg plugin
loading (trying to get the class_init_rec_mutex while holding the in the Gst
gst_plugin_loading_mutex) and at the same time we create a GES effect which in
turns lead to trying to get the class_init_rec_mutex while holding
gst_plugin_loading_mutex) -> Deadlock
