LibVLC.NET in GTK#

Question

I use LibVLC.NET wrapper in GTK#. And I have already played video using this example:

LibVLCLibrary library = LibVLCLibrary.Load(null);
IntPtr inst, mp, m;

inst         


        

Answer 1

Depending on the platform, you need to call libvlc_media_player_set_xwindow (Linux), libvlc_media_player_set_hwnd (Windows), or libvlc_media_player_set_nsobject (OSX).

The second parameter is an integer that is the handle to the native component that you want to embed the video.

Toolkits like GTK/GTK# should provide a method on the component that enables you to get this window handler.

For example this C# code can be used to get the needed window handle from a GTK Widget

private static Int32 Wid(Widget widget) {
    IntPtr windowPtr = gtk_widget_get_window(widget.Handle);
    if(windowPtr != IntPtr.Zero) {
        IntPtr xidPtr = gdk_x11_drawable_get_xid(windowPtr);
        if(xidPtr != IntPtr.Zero) {
            return xidPtr.ToInt32();
        }
    }
    return 0;
}

You only need to do this once after you create your media player and the native component, you do not need to do it each time you play media.
