IPropertySetter::AddProp method
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
Note
[Deprecated. This API may be removed from future releases of Windows.]
The AddProp method adds a property to the property setter, with an array of time-value pairs defining the value of the property over a range of time.
Syntax
HRESULT AddProp(
[in] DEXTER_PARAM Param,
[in] DEXTER_VALUE *paValue
);
Parameters
-
Param [in]
-
DEXTER_PARAM structure that specifies the property. The nValues member of the structure must equal the size of the array given in the paValue parameter.
-
paValue [in]
-
Pointer to an array of DEXTER_VALUE structures that contain time-value pairs. The array must be in ascending time order. The times are relative to the starting time of the effect or transition.
Return value
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
The first DEXTER_VALUE structure must specify a reference time of zero and an interpolation flag (dwInterp) of DEXTERF_JUMP, or the method returns an error.
