在媒体播放器元素或 LibVLCSharp 播放器上添加图层

我想在视频顶部添加椭圆形等形状。现在，如果我在媒体播放器元素上添加一个形状，我可以在 wpf 设计器中看到它但在运行时看不到它。

   <Grid>

        <controls:MediaPlayerElement x:Name="mediaPlayerElement"
            Source="https://mediaplatstorage1.blob.core.windows.net/windows-universal-samples-media/elephantsdream-clip-h264_sd-aac_eng-aac_spa-aac_eng_commentary-srt_eng-srt_por-srt_swe.mkv"
            AreTransportControlsEnabled="True" />
        <Grid>
            <Ellipse HorizontalAlignment="Center" Height="155"  Width="273" Fill="Black" Opacity="100" />
        </Grid>
    </Grid>

与 VLClibSharp 播放器相同。唯一的区别是，对于这个播放器，我在 wpf 设计器中看不到形状。

我怎样才能在运行时看到形状？

原文

I want to add shapes like ellipse on top of the video.
right now if i add a shape over the media player element i can see it in the wpf desinger
but can not see it in runtime.

   <Grid>

        <controls:MediaPlayerElement x:Name="mediaPlayerElement"
            Source="https://mediaplatstorage1.blob.core.windows.net/windows-universal-samples-media/elephantsdream-clip-h264_sd-aac_eng-aac_spa-aac_eng_commentary-srt_eng-srt_por-srt_swe.mkv"
            AreTransportControlsEnabled="True" />
        <Grid>
            <Ellipse HorizontalAlignment="Center" Height="155"  Width="273" Fill="Black" Opacity="100" />
        </Grid>
    </Grid>

same with the VLClibSharp player. the only diffrence is that with this player i dont see the shape in the wpf designer.

how can i make the shapes seen in runtime?
