Vista has a cool feature called DreamScene. It lets you play a video file on your computer’s desktop. However, it’s available only on Ultimate edition of Vista. You can somehow simulate it on Windows machines using VLC Media Player.
- Download VLC Media Player from this site and install it.
- Change the “Video output module” to “DirectX video output” by following this guide.
- Play a video file of your choice. Now click on Video menu and select Wallpaper.
- If you want to play a short file again and again. Click on View menu and select Playlist. In the Playlist dialog, select the file and click on the icon “Repeat one“. Close the Playlist dialog and enjoy!
I forgot to mention that when you run VLC media player in DirectX video output mode, the Aero color scheme will be disabled. The Aero color scheme will be restored once you exit out VLC media player.
