Xamarin Forms: Plugin.MediaManager & Plugin.MediaManager.Forms don't display the video in XAML VideoView

Question

I want to substitute XCT:MediaElement with Plugin.MediaManger & Plugin.MediaManager.Forms for my videos to play cross-platform. Documentation I've read this like 5 times and it still doesn't make any sense. I'm putting my video into Assets in Android and using XAML code below. The picture is the output I get on the screen, it's just a black background which I can change to any color...

I've added the Init() to the MainActivity and also to the AppDelegate. Followed everything step by step.

What really doesn't make any sense from the documentation is (Examples). CrossMediaManager is a static class. I cannot create a new instance of static classes so I cannot actually assign anything to the layout. How does it suppose to play anything on the screen if there is nothing that can actually consume this?

await CrossMediaManager.Current.PlayFromAssembly("somefile.mp3", typeof(BaseViewModel).Assembly);
await CrossMediaManager.Current.PlayFromResource("assets:///somefile.mp3");
await CrossMediaManager.Android.PlayFromResource(Resource.Raw.somefile.ToString());

Further, on the documentation you come across the Xamarin.Forms part where it shows how to do this is XAML with mm:ViewView now this makes more sense and I can also assign an x:Name to it and pass through MVVM pattern through the Behind Code to the ViewModel and so on, but this would be cool if the video played in the first place...

Any idea why this is happening?
Many Thanks in Advance.

Nuget Packges I've added: Plugin.MediaManager & Plugin.MediaManager.Forms

<StackLayout BackgroundColor="Red"
                HorizontalOptions="CenterAndExpand"
                VerticalOptions="CenterAndExpand"
                WidthRequest="400"
                HeightRequest="600"
                Margin="10"
                Padding="20">
    <mm:VideoView VerticalOptions="FillAndExpand"
                    Source="assets:///pea2.mp4"
                    AutoPlay="True"
                    ShowControls="True" />
</StackLayout>

Answer 1

At first, I install the Plugin.MediaManger & Plugin.MediaManager.Forms two packages in all the project, such as PCL(forms part), android part and ios part.

And then I added the following code in the MainActivity:

    protected override void OnCreate(Bundle savedInstanceState)
        {
            base.OnCreate(savedInstanceState);

            Xamarin.Essentials.Platform.Init(this, savedInstanceState);
            global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
                  CrossMediaManager.Current.Init(this);
            CrossMediaManager.Current.AutoPlay = true;
            LoadApplication(new App());
        }

And in the MainPage.Xaml:

    <StackLayout>
        <mm:VideoView VideoAspect="AspectFit" VerticalOptions="FillAndExpand" Source="https://www.appsloveworld.com/wp-content/uploads/2018/10/sample-mp4-video.mp4" ShowControls="True"/>
    </StackLayout>

And here is the result image on the android 11 emulator:

Note, according to the issue I mentioned in the comments, the plugin will work on the android 12 after adding the CrossMediaManager.Current.Speed = 1F;. But it will throw exception when I added it. It's strange.
