IPropertySetter::CloneProps 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 CloneProps method clones a set of properties from this property setter and adds them to a new property setter.
Syntax
HRESULT CloneProps(
[out] IPropertySetter **ppSetter,
[in] REFERENCE_TIME rtStart,
[in] REFERENCE_TIME rtStop
);
Parameters
-
ppSetter [out]
-
Receives a pointer to the IPropertySetter interface of the new property setter.
-
rtStart [in]
-
Start time of the range of values to clone, in 100-nanosecond units.
-
rtStop [in]
-
Reserved.
Return value
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
Only values that fall after the specified start time are cloned. The times on the cloned values are then adjusted relative to the start time. For example, if rtStart is 20000000 (2 seconds), then a value at time 30000000 (3 seconds) is cloned with time 10000000 (1 second). Finally, each cloned property is given an initial value equal to the value of the original property at the start time (correctly interpolated if necessary). In effect, the property data is split at the specified start time.
If the method succeeds, the IPropertySetter interface that it returns has an outstanding reference count. Be sure to release the interface when you are finished using it.
