Here’s a sample on how to use the new support for video files in XNA Game Studio 3.1.

All you have to do is add the video file (wmv) to your Content project, and you’re ready to use it with a few lines of code.

The sample loads a video containing a montage of XNA games, released some while ago. After loading it, you can view it in 4 ways (use spacebar/gamepad A to change):

• simple
• full-screen
• using a post-processing shader (reusing some code from Dark Codex’s tutorials)
• on a rotating sphere object

Here’s some screenshots:

And here’s the sample: VideoSample.zip

P.S. If a video file you have doesn’t work from the first try, try re-encoding it with Windows Movie Maker.
