How to set media source for streaming/casting and play it to device? (+some other questions)

[Weissu]

1. With basic Windows MediaPlayerElement I can open the source and cast it to device by code (C#). But how to do this same with VLC.MediaElement? Tried to find answer somewhere else but couldn't find.

2. Where I can find some kind of online manual about VLC.MediaElement? Or is there anything like this?

3. Is it possible to "write" cover picture into file? I like if file appears in FileExplorer with correct picture (thumb). (hope u understand what I mean)

4. Is it possible to mux str (or other format) subtitles into video stream?

5. Thanks for everyone behind this project. Great work!
