Experimental for testing - not complete working (audio problem at window change): QuadPiP added for VU+ Solo 4K, VU+ Duo 4k, VU+ Duo 4K SE, VU+ Ultimo 4K, VU+ Uno 4K SE and VU+ Uno 4K. Use --enable-pip and --enable-quadpip for these devices. BUT: VU+ Solo 4K has only support for 3 real video devices.
