WPF用VLC显示RTSP视频
场景
vlc是一个开源的解码库，有很多的版本当然也有WPF的版本，但是WPF其实是WinForm的基础上实现的。所有控件不自己处理的话，一直处于顶层。但它可以自带解码和显示的功能
操作
下载对VLC播放器，找到安装目录把libvlc.dll，libvlccore.dll，和plugins文件夹拿出来，插件看自己的需要，用多少加多少。一般方便管理我们都会在工程目录下新建一个文件夹如libvlc_x64，32位的可以x86。
之后我们引用这些dll
我们在xaml中添加VlcControl，代码如下
<Window x:Class="TestVideo.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:TestVideo"
xmlns:wpf="clr-namespace:Vlc.DotNet.Wpf;assembly=Vlc.DotNet.Wpf"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<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="0" x:Name="myControl"/>
<Button Grid.Row="1" Click="OnPlayButtonClick">Play</Button>
<Button Grid.Row="2" Click="OnForwardButtonClick" x:Name="Forward">Forward</Button>
<Button Grid.Row="3" Click="GetLength_Click" x:Name="GetLength">Get Length</Button>
<Button Grid.Row="4" Click="GetCurrentTime_Click" x:Name="GetCurrentTime">Get Current Time</Button>
<Button Grid.Row="5" Click="SetCurrentTime_Click" x:Name="SetCurrentTime">Set Current Time to 5s</Button>
</Grid>
</Window>
在播放前要指定引用插件和库所在的路径，我们在load里面，自己的工程不要写在这，会影响性成的。
// Use 64 bits library
this.myControl.MediaPlayer.VlcLibDirectory = new DirectoryInfo(System.IO.Path.Combine(Environment.CurrentDirectory, "libvlc_x64"));
var options = new string[]
{
// VLC options can be given here. Please refer to the VLC command line documentation.
};
this.myControl.MediaPlayer.VlcMediaplayerOptions = options;
// Load libvlc libraries and initializes stuff. It is important that the options (if you want to pass any) and lib directory are given before calling this method.
this.myControl.MediaPlayer.EndInit();
我们可以做的操作就很多了。如下
private void OnPlayButtonClick(object sender, RoutedEventArgs e)
{
myControl.MediaPlayer.Play(new Uri("rtsp://184.72.239.149/vod/mp4://BigBuckBunny_175k.mov"));
//本地视频写写本地路径
}
private void OnForwardButtonClick(object sender, RoutedEventArgs e)
{
myControl.MediaPlayer.Rate = 2;
}
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 = 5000;
SetCurrentTime.Content = myControl.MediaPlayer.Time + " ms";
}
效果如下
提示
就是视频的黑框，所以大小自己要处理好
wpf控件其实是winform来实现的
vlc解码前面会有一段预加载，
源码
所有的东西都有自己的优点和缺点，不要拿短来比长。做界面做样式只是一个模块，要有整体把握，不然软件或者网站都是问题，代码维护也是问题。
