Rendering Errors

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

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:

  • The error code is contained in the ErrorCode parameter.
  • The description is contained in the ErrorString parameter.
  • The description is contained in the ErrorString parameter.
  • If there is extra information, the VARIANT type is contained in the vt member of the VARIANT pointed to by pExtraInfo.

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.
