Playing a Video Crashes To Desktop On Windows 7

Summary

Playing a video (any video, as far as I know) will crash to desktop on Windows 7. Happens every time.

Minimal project and steps to reproduce

1. Start a new empty project
2. Import VLC Unity
3. Open the minimalplayback example
4. Comment out line 24 of minimalPlayback.cs so it doesn't just crash on start //PlayPause();
5. Make a build
6. Run it on Windows 7
7. Press the play button and watch it crash.

What is the current bug behavior?

Playing a video crashes the build (on Windows 7.)

What is the expected correct behavior?

Playing a video does not crash the build. Windows 7 should basically work the same as Windows 10.

Does it work on other plaforms? Does it work with the official VLC apps?

Right now VLC for Unity only supports one platform. Certainly VLC works fine on Windows 7.

Environment

• OS: Windows
• Version 7
• Device: PC
• LibVLC version and architecture 4.0.0 x64
• LibVLCSharp version Not quite sure how to check this, sorry.
• VLC Unity plugin version 0.1.4
• Scripting backend used Mono

Possible fixes

I don't have any fixes or workarounds for this. I have not tested whether it's only builds or whether the editor also crashes on play on windows 7.
