[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 Clone method makes a copy of the enumerator with the same enumeration state.
Receives a pointer to the IEnumPins interface of the new enumerator. The caller must release the interface.
Returns one of the following HRESULT
| Return code | Description |
|---|---|
|
Success. |
|
Insufficient memory. |
|
NULL pointer argument. |
|
The filter's state has changed and is now inconsistent with the enumerator. |
If the number of pins changes, the enumerator is no longer consistent with the filter, and the method returns VFW_E_ENUM_OUT_OF_SYNC. Discard any data obtained from previous calls to the enumerator, because it might be invalid. Update the enumerator by calling the IEnumPins::Reset method. You can then call the Clone method safely.
