Previously it was dispatched before the last video buffer, and audio buffers would follow afterwards. It's misleading to send the dropping=true message before both streams have really stopped, it can lead to races when someone is e.g. waiting for that message to send EOS. Also added some debug output. https://bugzilla.gnome.org/show_bug.cgi?id=797145
