How to play video in full screen and keep it looping with MPlayer?

I would like to play a video file in full screen and automatically make it keep playing during an exhibition. On Linux, how to do it with MPlayer?

You can use this command

mplayer -fs -loop 0 video.mp4

Here, -fs make it fullscreen and -loop 0 makes it loop infinitely.
