IAMDecoderCaps interface (strmif.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
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.
