In the documentation of the property CurrentFramePosition of the ILMVCallback Interface it is said "It is recommended you call this property to get the current position from inside ILMVUserCallback::ReceiveProc rather than trying to get the current position from the graph or LTMM object".

Would it be possible to have one of the relevant LEADTOOLS examples (Callback or DrawOnVideo) modified to show how to do this?

I modified the LEADTOOLS Multimedia v17.5 C# video callback demo to show the CurrentFramePosition inside ILMVUserCallback::ReceiveProc.
I am attaching the modified demo. Please check the following code in the ReceiveProc function:
+--------------------+
System.Diagnostics.Debug.WriteLine("CurrentFramePosition = " + lmvCallBkParent.CurrentFramePosition.ToString());
+--------------------+

Thanks,
