Microsoft® DirectShow® Editing Services (DES) defines various error codes used to log rendering errors. If a project does not render correctly, the render engine calls the IAMErrorLog::LogError method. The following table summarizes the parameters given to LogError:
Note The error codes described here are not HRESULT values. For a list of HRESULT return values specific to DES, see Error and Success Codes.
