MediaCapture support

[NalonAu]

Current behavior

I have a Uno app using .NET 6 and using the latest WinUI. I have tried implementing a camera control using https://learn.microsoft.com/en-us/dotnet/api/communitytoolkit.winui.ui.controls.camerapreview?view=win-comm-toolkit-dotnet-7.0 ... I have had a lot of issues doing this.

Thanks to Martin he has explained the following:

Hi! The problem here is probably the fact that the control is using some APIs which are not yet implemented in Uno Platform (camera preview in general is not there yet), so probably the only way to work around this right now would be to write a platform-specific native control for this purpose.

But please file an issue for the fact that the control is not working, so we know it is something we should look into.

Expected behavior

Camera should work as per the community toolkit examples for Camera Preview

Thanks for the report. This class relies on (at least) MediaPlayer.Source and MediaCapture being implemented, which is currently not the case. If you want to capture images natively, for now your best option is to use the native APIs, like this one.
