Question

我打算编写一个可以同时从HTTP流媒体服务器播放两个音频流的应用程序。在开始之前，我想确定Windows Phone设备和API是否支持此功能。

我想我必须使用两个MediaElement实例。有什么想法或建议吗？

编辑：我尝试使用以下代码，第一个停止，第二个播放，当我开始第二个播放时，第一个播放：

    private void StopMedia1(object sender, RoutedEventArgs e) 
    { 
        media1.Stop(); 
    } 

    private void PauseMedia1(object sender, RoutedEventArgs e) 
    { 
        media1.Pause(); 
    } 

    private void PlayMedia1(object sender, RoutedEventArgs e) 
    { 
        media1.Play(); 
    } 

    private void StopMedia2(object sender, RoutedEventArgs e) 
    { 
        media2.Stop(); 
    } 

    private void PauseMedia2(object sender, RoutedEventArgs e) 
    { 
        media2.Pause(); 
    } 

    private void PlayMedia2(object sender, RoutedEventArgs e) 
    { 
        media2.Play(); 
    }

        <RowDefinition Height="*" /> 
        <RowDefinition Height="Auto" /> 
    </Grid.RowDefinitions> 
    <MediaElement x:Name="media1" Source="1.mp3" Margin="0,151,0,359" /> 
    <MediaElement x:Name="media2" Source="2.mp3" Margin="0,154,3,359" Grid.Column="2" /> 
    <!-- Stops media playback.--> 
    <Button Click="StopMedia1" Content="Stop" Margin="6,449,24,244" /> 
    <!-- Pauses media playback. --> 
    <Button Click="PauseMedia1" Content="Pause" Margin="0,538,24,143" /> 
    <!-- Begins media playback. --> 
    <Button Click="PlayMedia1" Content="Play" Margin="0,649,0,47" /> 
    <Button Click="PauseMedia2" Content="Pause" Grid.ColumnSpan="2" Margin="154,524,6,169" Grid.Column="1" /> 
    <Button Click="PlayMedia2" Content="Play" Grid.Column="2" Margin="0,612,12,59" /> 
    <Button Click="StopMedia2" Content="Stop" Margin="18,429,12,264" Grid.Column="2" /> 
</Grid>

提前致谢。

不，在Windows Phone 7 / 7.5中无法同时播放两个MediaElements。要做到这一点，你需要使用XNA的SoundEffect类，尽管我认为它不支持流式传输。
