• 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:

    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

     1 <Window x:Class="Vlc.DotNet.Wpf.Samples.MainWindow"
     2         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
     3         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
     4         xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
     5         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
     6         xmlns:local="clr-namespace:Vlc.DotNet.Wpf.Samples"
     7         xmlns:wpf="clr-namespace:Vlc.DotNet.Wpf;assembly=Vlc.DotNet.Wpf"
     8         mc:Ignorable="d"
     9         Title="MainWindow" Height="350" Width="525">
    10     <Grid>
    11         <Grid.RowDefinitions>
    12             <RowDefinition Height="*"/>
    13             <RowDefinition Height="Auto"/>
    14             <RowDefinition Height="Auto"/>
    15             <RowDefinition Height="Auto"/>
    16             <RowDefinition Height="Auto"/>
    17             <RowDefinition Height="Auto"/>
    18         </Grid.RowDefinitions>
    19 
    20         <wpf:VlcControl Grid.Row="0" x:Name="myControl"/>
    21 
    22         <Button Grid.Row="1" Click="OnPlayButtonClick">Play</Button>
    23         <Button Grid.Row="2" Click="OnForwardButtonClick" x:Name="Forward">Forward</Button>
    24         <Button Grid.Row="3" Click="GetLength_Click" x:Name="GetLength">Get Length</Button>
    25         <Button Grid.Row="4" Click="GetCurrentTime_Click" x:Name="GetCurrentTime">Get Current Time</Button>
    26         <Button Grid.Row="5" Click="SetCurrentTime_Click" x:Name="SetCurrentTime">Set Current Time to 5s</Button>
    27     </Grid>
    28 </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"/>

     1 using System;
     2 using System.IO;
     3 using System.Reflection;
     4 using System.Windows;
     5 
     6 namespace Vlc.DotNet.Wpf.Samples
     7 {
     8     /// <summary>
     9     /// Interaction logic for MainWindow.xaml
    10     /// </summary>
    11     public partial class MainWindow : Window
    12     {
    13         public MainWindow()
    14         {
    15             InitializeComponent();
    16             myControl.MediaPlayer.VlcLibDirectoryNeeded += OnVlcControlNeedsLibDirectory;
    17         }
    18 
    19         private void OnVlcControlNeedsLibDirectory(object sender, Forms.VlcLibDirectoryNeededEventArgs e)
    20         {
    21             var currentAssembly = Assembly.GetEntryAssembly();
    22             var currentDirectory = new FileInfo(currentAssembly.Location).DirectoryName;
    23             if (currentDirectory == null)
    24                 return;
    25             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
    26 e.VlcLibDirectory = new DirectoryInfo(Path.Combine(currentDirectory, @"......libx86")); 27 else 28 e.VlcLibDirectory = new DirectoryInfo(Path.Combine(currentDirectory, @"......libx64")); 29 } 30 31 private void OnPlayButtonClick(object sender, RoutedEventArgs e) 32 { 33 myControl.MediaPlayer.Play(new Uri("http://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_surround-fix.avi")); 34 //myControl.MediaPlayer.Play(new FileInfo(@"......Vlc.DotNetSamplesVideosBBB trailer.mov")); 35 } 36 37 private void OnForwardButtonClick(object sender, RoutedEventArgs e) 38 { 39 myControl.MediaPlayer.Rate = 2; 40 } 41 42 private void GetLength_Click(object sender, RoutedEventArgs e) 43 { 44 GetLength.Content = myControl.MediaPlayer.Length + " ms"; 45 } 46 47 private void GetCurrentTime_Click(object sender, RoutedEventArgs e) 48 { 49 GetCurrentTime.Content = myControl.MediaPlayer.Time + " ms"; 50 } 51 52 private void SetCurrentTime_Click(object sender, RoutedEventArgs e) 53 { 54 myControl.MediaPlayer.Time = 5000; 55 SetCurrentTime.Content = myControl.MediaPlayer.Time + " ms"; 56 } 57 } 58 }
