TakeSnapshot doesn't work on libvlc UWP - Workedaround

Summary

I have been unable to get TakeSnapshot to work in my basic UWP test app. It always returns TRUE, but never saves a file. I have tried numerous formats for the path string. The UWP app is enabled for saving to the "Pictures" library and I have verified that the app can save there. Any help would be appreciated.

Minimal project and steps to reproduce

Repo link https://Tropicware@dev.azure.com/Tropicware/BasicVLC/_git/BasicVLC Open solution in Visual Studio. Run/debug x86 wait for video stream to play. Enter path to the pictures library for windows account EG. c:\Users\username\Pictures Press the SnapShot Button. Check pictures directory for snapshot.

What is the current bug behavior?

TakeSnapShot does not save a file.

What is the expected correct behavior?

SnapShot file is saved in the allowed Pictures Library set by the path string.

Environment

OS: Windows 10 64bit
Version 1803
Device: Lenovo PC
LibVLC VideoLAN.LibVLC.UWP Nuget 3.11
LibVLCSharp LibVLCSharp Nuget 3.1.0

Possible fixes

Maybe the VLC dll that saves the snapshot does not have the same permissions to save as the UMP app?
