ICodecAPI::SetAllSettingsWithNotify method (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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetAllSettingsWithNotify method reads codec properties from a stream, sets them on the codec, and returns a list of the properties that changed.

Syntax

HRESULT SetAllSettingsWithNotify(
  [in]  IStream *__MIDL__ICodecAPI0002,
  [out] GUID    **ChangedParam,
  [in]  ULONG   *ChangedParamCount
);

Parameters

[in] __MIDL__ICodecAPI0002

Return value

This method can return one of these values.
