Using MediaPlayerSurface with WinUI3

[adarsha-bhat]

I am trying to convert a code that uses MediaPlayerSurface to WinUI3.

https://docs.microsoft.com/en-us/windows/uwp/audio-video-camera/play-audio-and-video-with-mediaplayer#use-mediaplayersurface-to-render-video-to-a-windowsuicomposition-surface

So far I could not find any way to convert it to WinUI3 as the interfaces are not compatible. MediaPlayerSurface.CompositionSurface is of type Windows.UI.Composition.ICompositionSurface, I could not find any method that exposes an interface compatible with WinUI3.

Is there any workaround?
