Native Linux Support

Hi, so after WPF is done, i looked into another way of native implementation. For now it's very basic. Using Gtk# (Gtk2, stetic on MonoDevelop) it should be possible building a UserControl. Unfortunately, i have not found a way for Gtk3/Glade yet.

So if this needed, i would start working on it.

• Gtk2-Support using LibVLCSharp.Shared.MediaPlayer.XWindow
  • This requires VideoView to act as a Window
  • Need to verify, if it supports child elements
• Gtk3-Support
  • Do not know the C functions to use in DllImport yet
