Summary

There is an issue with uno platforms and vlc libs.

Minimal project and steps to reproduce

SampleUNO.zip

What is the current bug behavior?

Well it is very simple, took your example copy it over to my project and run it. It does work on UWP, but not on android.

What is the expected correct behavior?

to run it on all platforms.

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