Install the video player mplayer in centos

Watch the video when installing mplayer on centos Desktop
Today, we installed the centos 6.3 desktop environment to work with the Java development environment.
After the event, I found that the TV player in the centos6.3 desktop application could not play videos such as AVI (it was originally a command line)
In itself, centos is a server system that implicitly integrates audio and video software. Then we should use the common mplayer player as our video player.
Because the system I installed is 64-bit, the link is 64-bit.

If you can play the audio but cannot play the video, the following error is prompted:
Error opening/initializing the selected video_out (-vo) Device
In fact, the solution is very simple:
Open mplayer. Right-click --> select "Preferences" --> "video" tab --> select "X11" in "availabe drivers". --> Click "OK" to disable the settings. Restart mplayer. Open a video to check and solve the problem.
