WPF播放器

最近由于工作需要，需要做一个播放软件，在网上参考了很多例子，园子里有很多代码。其中最多的就是wpf自带的MediaElement控件，或者VLC视频播放器。

先附我自己查询资料的链接：

MediaEmelent控件例子

VLC

由于我电脑可能是Ghost系统 或者由于被优化了。我发现我的MediaElement无法播放任何视频。通过控制面板关闭媒体中心之后，再也打不开了。真是坑！！！

只能放弃自带控件，查到有一个VLC的NET版。so。。。

附vlc.dotnet的github链接

首先，自己在nuget里面下载所需要的扩展：

完成之后 就看示例代码咯，github里面是有example的

 <Window x:Class="Vlc.DotNet.Wpf.Samples.MainWindow"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
         xmlns:local="clr-namespace:Vlc.DotNet.Wpf.Samples"
         xmlns:wpf="clr-namespace:Vlc.DotNet.Wpf;assembly=Vlc.DotNet.Wpf"
         mc:Ignorable="d"
         Title="MainWindow" Height="" Width="">
     <Grid>
         <Grid.RowDefinitions>
             <RowDefinition Height="*"/>
             <RowDefinition Height="Auto"/>
             <RowDefinition Height="Auto"/>
             <RowDefinition Height="Auto"/>
             <RowDefinition Height="Auto"/>
             <RowDefinition Height="Auto"/>
         </Grid.RowDefinitions>

         <wpf:VlcControl Grid.Row="" x:Name="myControl"/>

         <Button Grid.Row="" Click="OnPlayButtonClick">Play</Button>
         <Button Grid.Row="" Click="OnForwardButtonClick" x:Name="Forward">Forward</Button>
         <Button Grid.Row="" Click="GetLength_Click" x:Name="GetLength">Get Length</Button>
         <Button Grid.Row="" Click="GetCurrentTime_Click" x:Name="GetCurrentTime">Get Current Time</Button>
         <Button Grid.Row="" Click="SetCurrentTime_Click" x:Name="SetCurrentTime">Set Current Time to 5s</Button>
     </Grid>
 </Window>

首先加上 xmlns:wpf="clr-namespace:Vlc.DotNet.Wpf;assembly=Vlc.DotNet.Wpf"

然后加上 <wpf:VlcControl Grid.Row="0" x:Name="myControl"/>

 using System.IO;

 using System.Windows;

 namespace Vlc.DotNet.Wpf.Samples
 {
     /// <summary>
     /// Interaction logic for MainWindow.xaml
     /// </summary>
     public partial class MainWindow : Window
     {
         public MainWindow()
         {
             InitializeComponent();
             myControl.MediaPlayer.VlcLibDirectoryNeeded += OnVlcControlNeedsLibDirectory;
         }

         private void OnVlcControlNeedsLibDirectory(object sender, Forms.VlcLibDirectoryNeededEventArgs e)
         {
             var currentAssembly = Assembly.GetEntryAssembly();
             var currentDirectory = new FileInfo(currentAssembly.Location).DirectoryName;
             if (currentDirectory == null)
                 return;
             if (AssemblyName.GetAssemblyName(currentAssembly.Location).ProcessorArchitecture == ProcessorArchitecture.X86)
　　　　　　　　　　　　//vlc的dll路径，自己下载vlc播放器里面的libvlc.dll libvlccore.dll以及plugins文件夹
                 e.VlcLibDirectory = new DirectoryInfo(Path.Combine(currentDirectory, @"..\..\..\lib\x86\"));
             else
                 e.VlcLibDirectory = new DirectoryInfo(Path.Combine(currentDirectory, @"..\..\..\lib\x64\"));
         }

         private void OnPlayButtonClick(object sender, RoutedEventArgs e)
         {
             myControl.MediaPlayer.Play(new Uri("http://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_surround-fix.avi"));
             //myControl.MediaPlayer.Play(new FileInfo(@"..\..\..\Vlc.DotNet\Samples\Videos\BBB trailer.mov"));
         }

         private void OnForwardButtonClick(object sender, RoutedEventArgs e)
         {
             myControl.MediaPlayer.Rate = ;
         }

         private void GetLength_Click(object sender, RoutedEventArgs e)
         {
             GetLength.Content = myControl.MediaPlayer.Length + " ms";
         }

         private void GetCurrentTime_Click(object sender, RoutedEventArgs e)
         {
             GetCurrentTime.Content = myControl.MediaPlayer.Time + " ms";
         }

         private void SetCurrentTime_Click(object sender, RoutedEventArgs e)
         {
             myControl.MediaPlayer.Time = ;
             SetCurrentTime.Content = myControl.MediaPlayer.Time + " ms";
         }
     }
 }
