Mplayer is only supported on Microsoft Windows and macOS operating systems. Linux and Unix are not currently supported. To get the most from a voice and video service, you’ll want to be seen and heard yourself! For that, you’ll need a microphone and a webcam, available at any local computer retail store. When you register for Mplayer, you’ll download our free chat software. Those are the only components you need to take full advantage of Mplayer.
