IRenderEngine::SetSourceNameValidation 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetSourceNameValidation method specifies how the render engine validates file names.
Syntax
HRESULT SetSourceNameValidation(
BSTR FilterString,
IMediaLocator *pOverride,
LONG Flags
);
Parameters
-
FilterString
-
BSTR value containing pairs of filter strings, formatted as required by the lpstrFilter member of the OPENFILENAME structure. The media locator uses this filter if it presents an Open File dialog box to the end user.
-
pOverride
-
Optional pointer to the IMediaLocator interface of a media locator to use in place of the default. To use the default media locator, set the value of this parameter to NULL. See Remarks for more information.
-
Flags
-
Bitwise combination of File Name Validation Flags specifying the behavior of the media locator. The SFN_VALIDATEF_CHECK flag must be present. The SFN_VALIDATEF_hlinkMUTED flag has no effect with this method.
Return value
Returns one of the following HRESULT values:
| Return code | Description |
|---|---|
|
Success. |
|
Render engine failed to initialize. |
Remarks
Using the pOverride parameter, you can supply your own custom implementation of the IMediaLocator interface. For example, the default media locator does not notify an application about the files that it finds (or cannot find). To get around this limitation, you could implement a custom media locator, making it a wrapper for the default version. Then pass IMediaLocator::FindMediaFile calls directly to the default version and examine the return value.
Currently, this method does not validate dynamically loaded sources. See IRenderEngine::SetDynamicReconnectLevel.
Note
The header file Qedit.h is not compatible with Direct3D headers later than version 7.
Note
To obtain Qedit.h, download the Microsoft Windows SDK Update for Windows Vista and .NET Framework 3.0. Qedit.h is not available in the Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 Service Pack 1.
