How to embed native control or get native handle of existing control

I’m working on video player (GStreamer based) and want to render video inside Avalonia app.

I’m using Panel in WinForms app as video window.

I need some area inside Avalonia window (Panel for example) that can provide native window handle to draw on it. It’s possible for Win32 control or Gtk controls for example.

I can get handle for entire Window but that’s not what I need.

var screenHandle = ((Avalonia.Win32.WindowImpl) ((TopLevel) pnScreen.GetVisualRoot())?.PlatformImpl)?.Handle?.Handle ?? IntPtr.Zero;

As alternative maybe some way to embed native platform controls that have handle into Avalonia window.

0.10 will have an equivalent for HwndHost, see https://github.com/AvaloniaUI/Avalonia/blob/master/samples/interop/NativeEmbedSample/EmbedSample.cs

is it possible to embed SDL2 windows on AvaloniaUI? I did try to do that on WPF with HwndHost, but the BuildWindowCore() throws an InvalidOperationException when returning the HandleRef.
