Question

我对Vlc.DotNet（Wpf）说道！我想开发一个CCTV应用程序，在一个页面上支持100个摄像机实时视图！我有一个10x10网格，可以在单元格中显示视频。

问题是应用程序变慢并在36个视频片段后停止。

这是我的测试：

XAML：

<Window x:Class="vlc_stream_test.videoGrid"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:Wpf="clr-namespace:Vlc.DotNet.Wpf;assembly=Vlc.DotNet.Wpf" Title="Video Lan Grid" Height="500" Width="525" Loaded="Window_Loaded">
<Grid Name="root" ShowGridLines="True">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="1*"/>
        <ColumnDefinition Width="1*"/>
        <ColumnDefinition Width="1*"/>
        <ColumnDefinition Width="1*"/>
        <ColumnDefinition Width="1*"/>
        <ColumnDefinition Width="1*"/>
        <ColumnDefinition Width="1*"/>
        <ColumnDefinition Width="1*"/>
        <ColumnDefinition Width="1*"/>
        <ColumnDefinition Width="1*"/>
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="1*"/>
        <RowDefinition Height="1*"/>
        <RowDefinition Height="1*"/>
        <RowDefinition Height="1*"/>
        <RowDefinition Height="1*"/>
        <RowDefinition Height="1*"/>
        <RowDefinition Height="1*"/>
        <RowDefinition Height="1*"/>
        <RowDefinition Height="1*"/>
        <RowDefinition Height="1*"/>
    </Grid.RowDefinitions>
</Grid>

代码背后的代码：

try
{
   VlcContext.LibVlcDllsPath = CommonStrings.LIBVLC_DLLS_PATH_DEFAULT_VALUE_AMD64;
   VlcContext.LibVlcPluginsPath = CommonStrings.PLUGINS_PATH_DEFAULT_VALUE_AMD64;
}
catch
{
   VlcContext.LibVlcDllsPath = CommonStrings.LIBVLC_DLLS_PATH_DEFAULT_VALUE_X86;
   VlcContext.LibVlcPluginsPath = CommonStrings.PLUGINS_PATH_DEFAULT_VALUE_X86;
}
VlcContext.StartupOptions.IgnoreConfig = true;
VlcContext.StartupOptions.LogOptions.LogInFile = false;
VlcContext.StartupOptions.LogOptions.ShowLoggerConsole = false;
VlcContext.StartupOptions.LogOptions.Verbosity = VlcLogVerbosities.None;
Vlc.DotNet.Core.VlcContext.StartupOptions.AddOption("--network-caching=1000");
Vlc.DotNet.Core.VlcContext.StartupOptions.AddOption("--no-skip-frames");
Vlc.DotNet.Core.VlcContext.StartupOptions.AddOption("--no-video-title");
Vlc.DotNet.Core.VlcContext.StartupOptions.AddOption("--live-caching=10000");
VlcContext.Initialize();
InitializeComponent();
root.Background = Brushes.DarkGreen;
for (int i = 0; i < 10; i++)
     for (int j = 0; j < 10; j++)
     {
      var visBrush = new VisualBrush() { Stretch = Stretch.UniformToFill };
      Grid g = new Grid() {Background = visBrush, Margin = new Thickness(1) };

      g.PreviewMouseDown += (sender, e) =>
      {
           VlcControl vlc = new VlcControl() { Media = new LocationMedia("file:///C:/Users/Public/Videos/wildlife.wmv") };
           Binding binding = new Binding("VideoSource") { Source = vlc };
           var imgBox = new Image();
           imgBox.SetBinding(Image.SourceProperty, binding);
           visBrush.Visual = imgBox;
       };
       root.Children.Add(g);
       Grid.SetColumn(g, j);
      Grid.SetRow(g, i);
  }

我使用的视频规范：

分辨率：128x96

bitRate：72 kb / s

音频：无

视频格式：wmv1

Here is the video (298.67 KB)

我需要一个解决我问题的解决方案...... 感谢。

最后，我使用AForge.Net在一个页面中显示了100个不同的视频流。 AForge更快更快比VLC更轻！

要在wpf中使用Aforge.Net，请查看此answer！
