我修改了MediaTransportControls的样式，并设置了 缓冲时，“BufferingProgressBar.Visibility”变为“折叠”

<VisualStateGroup x:Name="MediaStates">
    <VisualState x:Name="Normal" />
    <VisualState x:Name="Buffering">
        <VisualState.Setters>
            <Setter Target="BufferingProgressBar.Visibility" Value="Collapse" />
        </VisualState.Setters>
    </VisualState>
    <VisualState x:Name="Loading">
        <VisualState.Setters>
            <Setter Target="BufferingProgressBar.Visibility" Value="Collapse" />
        </VisualState.Setters>

        <Storyboard>
            <DoubleAnimation Storyboard.TargetName="ProgressSlider"
                Storyboard.TargetProperty="Opacity"
                To="0"
                Duration="0" />
            <DoubleAnimation Storyboard.TargetName="MediaControlsCommandBar"
                Storyboard.TargetProperty="Opacity"
                To="0"
                Duration="0" />
        </Storyboard>
    </VisualState>

</VisualStateGroup>
