IAMDecoderCaps Interface

The IAMDecoderCaps interface returns capabilities information from an MPEG decoder filter. The capabilities reported through this interface include whether the decoder supports the Video Mixing Renderer filter and whether it supports DirectX Video Acceleration.

Some DirectShow components, such as the DVD Graph Builder, use this interface to determine the correct filter graph to build. Applications might use this interface to query the decoder's capabilities.

In addition to the methods inherited from IUnknown, the IAMDecoderCaps interface exposes the following method.
