Playing a Video

To play a video

Add a video to the game project using the steps outlined in loading resources.

  1. In LoadContent, load the video using the ContentManager.

  2. Create a new instance of the VideoPlayer.

    Video video;
VideoPlayer player;
Texture2D videoTexture;

protected override void LoadContent()
{
    // Create a new SpriteBatch, which can be used to draw textures.
    spriteBatch = new SpriteBatch(GraphicsDevice);
    video = Content.Load<Video>("video");
    player = new VideoPlayer();
}

  3. In the Update method, play the video.

    Tip

    Set IsLooped to true if you want the video to repeat.

    protected override void Update(GameTime gameTime)
{
    ...
    if (player.State == MediaState.Stopped)
    {
        player.IsLooped = true;
        player.Play(video);
    }
    ...
    base.Update(gameTime);
}

  4. In Draw, if the VideoPlayer is not stopped, call GetTexture to get a copy of the latest frame of video.

  5. Create a Rectangle defining where on-screen the video will appear.

  6. If the texture is not null, draw it on-screen using SpriteBatch.Draw.

    protected override void Draw(GameTime gameTime)
{
    GraphicsDevice.Clear(Color.CornflowerBlue);

    // Only call GetTexture if a video is playing or paused
    if (player.State != MediaState.Stopped)
        videoTexture = player.GetTexture();

    // Drawing to the rectangle will stretch the 
    // video to fill the screen
    Rectangle screen = new Rectangle(GraphicsDevice.Viewport.X,
        GraphicsDevice.Viewport.Y,
        GraphicsDevice.Viewport.Width,
        GraphicsDevice.Viewport.Height);

    // Draw the video, if we have a texture to draw.
    if (videoTexture != null)
    {
        spriteBatch.Begin();
        spriteBatch.Draw(videoTexture, screen, Color.White);
        spriteBatch.End();
    }

    base.Draw(gameTime);
}
