问题描述

我已经在Stackoverflow上问过了，但是没有任何答案，非常抱歉.也许我们可以在这里废弃它.
我正在使用WPF MediaElement和OnButton播放视频，单击它会打开第二个窗口(我使用Screens.AllScreens [1]将其移动到第二个监视器).在第二个窗口中，我创建了一个新的mediaelement实例，并将值从mediaelement1.position放入mediaelemnt2.position.现在我在第二个窗口中有一秒钟的延迟...

有办法解决吗?

感谢您的帮助.

Hi,

I''ve already asked at Stackoverflow, but without any answers, so sorry for double post.
Maybe we can disuss it here.
I''m playing a video with the WPF MediaElement and OnButton Click it opens a second window (I move it with Screens.AllScreens[1] to my second monitor). On second window I''ve created a new instance of mediaelement and put the value from mediaelement1.position to mediaelemnt2.position. Now I have a one second delay in my second window ...

Is there a way to handle this?

Thanks for help

推荐答案

<Window ...>
    <Window.Resources>
        <VisualBrush x:Key="Media" Stretch="Uniform">
            <VisualBrush.Visual>
                <MediaElement Source="PathToMedia"/>
            </VisualBrush.Visual>
        </VisualBrush>
    </Window.Resources>
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>
        <Rectangle Fill="{StaticResource Media}"/>

        <Button Click="Button_Click" Grid.Row="1" Content="Click me!"/>
    </Grid>
</Window>

Window1.xaml.cs

private void Button_Click(object sender, RoutedEventArgs e)
{
    new Window2(Resources["Media"] as VisualBrush).Show();
}

Window2.xaml

<Window ...>
    <Rectangle Name="display"/>
</Window>

Window2.xaml.cs

public Window2(VisualBrush visualBrush)
{
    InitializeComponent();

    display.Fill = visualBrush;
}
