两个MediaElement之间的延迟

我在myForm上有两个媒体元素。我上传了相同的视频，但在MediaElement1和MediaElement2之间延迟了大约一秒。两个MediaElement之间的延迟

MediaElement1.Source = new Uri("D:\\test.avi", UriKind.Relative); 
MediaElement2.Source = new Uri("D:\\test.avi", UriKind.Relative); 
MediaElement1.Position = TimeSpan.Zero; 
MediaElement2.Position = TimeSpan.Zero; 
MediaElement1.LoadedBehavior = MediaState.Play; 
MediaElement2.LoadedBehavior = MediaState.Play;

XAML

<MediaElement x:Name="MediaElement1" Margin="0,0,5,126" /> 
<MediaElement x:Name="MediaElement2" Margin="0,0,15,126"/>

为什么会出现延迟，如何解决？

对不起，我添加了一个问题 – XmaksasX

你是否在任何东西中持有MediaElements帆布？ – sr28

以下代码无延迟地工作，有必要添加一个停止命令。

 private static OpenFileDialog OpenFile() 
     { 
      OpenFileDialog ofd; 
      ofd = new OpenFileDialog(); 
      ofd.AddExtension = true; 
      ofd.DefaultExt = "*.*"; 
      ofd.Filter = "media (*.*)|*.*"; 
      ofd.ShowDialog(); 
      return ofd; 
     } 

     private void loadm1_Click(object sender, RoutedEventArgs e) 
     { 
      OpenFileDialog ofd = OpenFile(); 
      M1.Source = new Uri(ofd.FileName, UriKind.Relative); 
      M1.Position = TimeSpan.Zero; 
      M1.LoadedBehavior = MediaState.Stop; 
     } 

     private void loadm2_Click(object sender, RoutedEventArgs e) 
     { 
      OpenFileDialog ofd = OpenFile(); 
      M2.Source = new Uri(ofd.FileName, UriKind.Relative); 
      M2.LoadedBehavior = MediaState.Stop; 
     } 

     private void btnStart_Click(object sender, RoutedEventArgs e) 
     { 
      M1.LoadedBehavior = MediaState.Play; 
      M2.LoadedBehavior = MediaState.Play; 
     } 

     private void btnPause_Click(object sender, RoutedEventArgs e) 
     { 
      M1.LoadedBehavior = MediaState.Pause; 
      M2.LoadedBehavior = MediaState.Pause; 
     }

XAML

<Grid> 
     <Grid.ColumnDefinitions> 
      <ColumnDefinition Width="252*"/> 
      <ColumnDefinition Width="265*"/> 
     </Grid.ColumnDefinitions> 
     <MediaElement x:Name="M1" Margin="0,0,5,126" /> 
     <MediaElement x:Name="M2" Grid.Column="1" Margin="0,0,15,126"/> 
     <Button x:Name="loadm1" Content="Load" HorizontalAlignment="Left" Margin="10,0,0,99" Width="75" Height="22" VerticalAlignment="Bottom" Click="loadm1_Click"/> 
     <Button x:Name="loadm2" Content="Load" Grid.Column="1" HorizontalAlignment="Left" Margin="10,0,0,99" Width="75" Height="22" VerticalAlignment="Bottom" Click="loadm2_Click"/> 
     <Button x:Name="btnStart" Content="Start" Margin="10,0,20,20" Grid.ColumnSpan="2" Height="22" VerticalAlignment="Bottom" Click="btnStart_Click"/> 
     <Button x:Name="btnPause" Content="Pause" HorizontalAlignment="Left" Margin="10,289,0,0" VerticalAlignment="Top" Width="75" Click="btnPause_Click"/> 

    </Grid>
