IAMErrorLog 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]

Note

[Deprecated. This API may be removed from future releases of Windows.]

 

The IAMErrorLog interface provides a callback method for error logging in DirectShow Editing Services (DES).

DES does not implement this interface. To perform error logging, implement this interface in your application and call IAMSetErrorLog::put_ErrorLog on the timeline. If an error occurs when you render the project, DES will call the IAMErrorLog::LogError method implemented by your application.

DES logs errors only when you render a project using the IRenderEngine interface. For example, if you save a project as a DirectShow filter graph (.grf format) and play the graph file, there is no error logging. For more information on using this interface, see Logging Errors.
