Current Behavior

I'm setting the BackgroundColor property in the MediaElement but it looks like the color doesn't change on iOS (looks OK on Android).

<toolkit:MediaElement Source="https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4"
                              ShouldShowPlaybackControls="False"
                              ShouldAutoPlay="True"
                              Volume="0"
                              ShouldLoopPlayback="True"
                              HeightRequest="300"
                              BackgroundColor="Red"
                              HorizontalOptions="Fill"
                              Aspect="AspectFit"
                              />

Expected Behavior

When setting the BackgroundColor property in the MediaElement, the color should be updated on iOS.

1. Clone the project https://github.com/juniorsaraviao/VideoSample/tree/master.

@vhugogarcia I can verify the behavior on Android as being buggy. This is a simple fix that I can apply for android only.

This issue also applies to windows and cannot be fixed. It is by design on windows. MS limits access to classes and has indicated in xaml repo that is that way by design and we have no way to change it.
