Windows SDK - Camera Application - Making it to work

After integrating WSDK and Getting Started exercises, I proceeded to coding the Camera Application following tutorial at https://developer.dji.com/windows-sdk/documentation/tutorials/index.html 

Though I followed the tutorial exactly, When I tried to run the app I got the following error:

Then I downloaded the completed app from GitHub and it runs well and I see the FPV image. So when I dug further I found the FFMpeg DLLs were not the same as in the completed sample.

The FFMpeg DLLs in my app as per the tutorial are shown below:

Where as these DLLs in the completed app are as follows:

So I replaced the FFMpeg DLLs in my app with that of completed app and everything worked fine.

So it seems FFMpeg DLLs packaged in the DJIVideoParser as directed by tutorial are not the correct ones. These should be updated.
