About Video Rendering in DirectShow

DirectShow provides several filters that render video:

Generally, the VMR-9 is preferred whenever possible, because it provides the best features, using the newest graphics APIs. For more information about using the VMR-7 and VMR-9 filters, see Using the Video Mixing Renderer.

Windowed Mode and Windowless Mode

A DirectShow video renderer can operate in either windowed mode or windowless mode.

The Video Renderer filter supports windowed mode only. The VMR-7 and VMR-9 filters support both modes. They default to windowed mode for backward compatibility.
