Ever since the last update “version 0.12.4 build(6406)” the local preview shows an empty window. No error thrown, nothing visible in the logs. I tried reinstalling once already but the problem persists.

The current project I’m working: . S

```auto
<App Theme="Basic" ClearColor="#200c50">
    <iOS.StatusBarConfig Style="Light" />

    <DockPanel>
        <Video Layer="Background" File="assets/FONDO.mp4" IsLooping="true" AutoPlay="true" StretchMode="UniformToFill" ContentAlignment="Center" Opacity="0.3" Padding="-10">
            <Blur Radius="3.31" />
        </Video>
    </DockPanel>
</App>

```

It’s the same for older projects and examples.

Just to be clear, this isn’t just an issue with your video, but also happens if you replace the `Video` tag with for instance `<Text Value="I render"/>`?

Can you please see if you have the samme issue when you do:

```auto
fuse create example MyExample
cd MyExample
fuse build -r -tdotnetexe

```

Hey, replacing the `Video` tag with `<Text Value="I render"/>` showed the text. So I changed the video tag into `<Video Layer="Background" File="assets/FONDO.mp4" IsLooping="true" AutoPlay="true" StretchMode="UniformToFill" ContentAlignment="Center" />` and it is playing correctly on the local preview. Which is ok since the blur wasn’t necesary. But the video wont play on an android device, I’ve tried with a preview and building an .apk

Currently tested it on an Samsung galaxy tab 3 and S3 mini

Hi!

Thanks for reporting, I have added a ticket for improving the error reporting from `<Video />`.

`E/Fuse.Video( 3223): setDataSourceFD failed.: status=0x80000000`

It basically says that it failed to set the data source. Have you tried other video files or even urls? When I test your code (with my own .mp4) it works without problems
