IAMErrorLog Interface

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.
