Decklink Access In Blackmagic Unreal Plugin

I'm trying to extend the Blackmagic Unreal plugin to get more information about the video stream to improve synchronization with a secondary input source. To do this, I need to call a method provided by the DeckLink SDK.

Previously, I had figured that the plugin would be directly calling the DeckLink SDK, but it is instead using BlackmagicLib.dll. It seems BlackmagicLib is encapsulating the actual communication to DeckLink, which I need to access for my application. My question is, how can I get the BlackMagicLib source code or, if that's not possible, how can I access the IDeckLinkVideoFrame in the OnFrameReceived callback from within the unreal plugin?
