IMediaLocator interface

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IMediaLocator interface provides methods for validating file names in DirectShow Editing Services (DES). Use this interface to ensure that a given file name and path correspond to an existing file. This interface also provides a way to search for the file at other locations, and to display an Open dialog box so that the user can locate the file.

The media locator implements this interface. The timeline and the render engine also support file name validation through the following methods:

• IAMTimeline::ValidateSourceNames: Validates and updates file names in the timeline.
• IRenderEngine::SetSourceNameValidation: Specifies how the render engine validates file names at rendering time.

Typically, a DES application will call these methods rather than directly create an instance of the media locator. For more information, see Using the Media Locator.
