IMediaDet::put_Filter 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 put_Filter method specifies a source filter for the media detector to use.
Important
Do not add the source filter to your own filter graph, or use a filter that is already in a filter graph. The media detector object automatically builds an internal filter graph, and putting the filter in another graph can cause unexpected results.
Syntax
HRESULT put_Filter(
[in] IUnknown *newVal
);
Parameters
-
newVal [in]
-
Pointer to the source filter's IUnknown interface.
Return value
Returns an HRESULT value. Possible values include the following:
| Return code | Description |
|---|---|
|
Success. |
|
newVal does not point to a filter. |
|
NULL pointer argument. |
Remarks
For most applications, it is simpler to call the IMediaDet::put_Filename method with the name of a source file.
