Here’s quick explanation about the problem:
-I am using ubuntu 8.10
-My notebook used ATI Radeon HD 3200 as VGA card
-I’ve installed the ATI driver downloaded from the ATI website
-I’ve installed the compiz fusion and the 3D cube with other features runs quite well.
-I’ve installed the gstreamer codec. (but still I can’t hear any sound.)
-When I played any movie file, the pictures of the movie is flickering
This is the problem this post going to solve. And this is going to work with VLC player.
open the VLC player form Application>>Sound& Video>>VLC playe
Open the VLC Preferences from VLC menubar Tools>>Preferences
Set the Show Settings to All.
Click Video>>Output Modules>> Then Change the Video Output mode from default to X11 Video Output.
Notes: Actually with Visual Effect on the Apperance Preferences set to none you can play the movie without flickering pictures. However,the explanation above solve the problem without setting the Visual Effect to none.
