IMediaParamInfo interface (medparam.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IMediaParamInfo interface retrieves information about the parameters that an object supports. The set of parameters that an object supports will not change over the lifetime of an application. To set parameter values, use the IMediaParams interface.
