IAMResourceControl 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IAMResourceControl interface opens and holds an audio device resource before the device is actually needed, so that playback can be guaranteed or the application can learn in advance that a device is not available.

The following filters implement this interface:

• Audio Capture filter.
• DirectSound Renderer filter.
• Audio Renderer (WaveOut) filter.
