	//
	//     udpsrc port=5005 ! application/x-rtp,media=video,encoding-name=H264 ! queue ! rtph264depay ! h264parse config-interval=1 disable-passthrough=true ! decodebin ! vaapisink
	//
	// (2) waylandsink is a bit broken, as it needs a RGB format, but its caps include non-RGB formats
	//     This results in crashes when videoconvert doesn't end up in the pipeline, so care must be taken
	//     if it is used, e.g. for testing:
	//
	//     videotestsrc pattern=smpte ! video/x-raw,format=BGRx,width=384,height=368 ! waylandsink
