基于rtmp+nginx 、vlc实现FFmpeg推流与wpf端拉流

这周在研究基于rtmp+nginx直播流的实现，现总结如下：

1.nginx部署

1.1将nginx_1.7.11.3_Gryphon.zip解压，启动nginx.bat文件移动至nginx_1.7.11.3_Gryphon解压后文件夹内，双击bat,启动nginx

1.2浏览器输入：http://localhost:1234/ 若出现如下页面，恭喜你部署成功！如未出现，可能是防火墙或者端口被占用，可修改nginx_1.7.11.3_Gryphonconf ginx-win-rtmp.conf中的端口号。

2.FFmpeg推流至服务器

2.1推流命令示例：打开cmd,cd到nginx_1.7.11.3_Gryphon路径下 输入 ffmpeg -re -i 11.mp4 -vcodec libx264 -acodec aac -f flv rtmp://127.0.0.1:1935/live/home 并回车 。rtmp://127.0.0.1:1935/live为推流应用，home为具体流的名称，值随意，如需多个推流同时进行，只需更改home，如rtmp://127.0.0.1:1935/live/test

3.WPF端集成vlc拉流

3.1  项目里先添加Vlc.DotNet.Core.dll，Vlc.DotNet.Core.Interops.dll，Vlc.DotNet.Wpf.dll，可直接用我的 .net4.0版本，亦可下载源码自己编译（https://github.com/ZeBobo5/Vlc.DotNet   需用vs2017及以上编译）并在xaml中添加xmlns:local="clr-namespace:Vlc.DotNet.Wpf;assembly=Vlc.DotNet.Wpf"引用，将libvlc解压至wpf生成路径下，libvlc包含必须的解码库文件及插件

3.2 后台代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using Vlc.DotNet.Wpf;
using System.Reflection;
using System.IO;
using Vlc.DotNet.Core;

namespace LiveStreamTest
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        private VlcVideoSourceProvider sourceProvider;
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            var currentAssembly = Assembly.GetEntryAssembly();
            var currentDirectory = new FileInfo(currentAssembly.Location).DirectoryName;
            // Default installation path of VideoLAN.LibVLC.Windows
            var libDirectory = new DirectoryInfo(System.IO.Path.Combine(currentDirectory, "libvlc", IntPtr.Size == 4 ? "win-x86" : "win-x64"));

            this.sourceProvider = new VlcVideoSourceProvider(this.Dispatcher);
            this.sourceProvider.CreatePlayer(libDirectory/* pass your player parameters here */);
            var mediaOptions = new[]
                {                    
                    " :network-caching=2000"
                };
            this.sourceProvider.MediaPlayer.Play("rtmp://127.0.0.1:1935/live/home",mediaOptions);//rtmp://114.242.105.17:1935/live/test
            //string file =@"D:1_soft
tmp
ginx_1.7.11.3_Gryphon11.mp4";
            //this.sourceProvider.MediaPlayer.Play(new FileInfo(file));//本地文件
            this.sourceProvider.MediaPlayer.Log += new EventHandler<VlcMediaPlayerLogEventArgs>(MediaPlayer_Log);
            this.sourceProvider.MediaPlayer.Manager.SetFullScreen(this.sourceProvider.MediaPlayer.Manager.CreateMediaPlayer(), true);
            Binding bing = new Binding();
            bing.Source = sourceProvider;
            bing.Path = new PropertyPath("VideoSource");
            img.SetBinding(Image.SourceProperty, bing);
        }

        void MediaPlayer_Log(object sender, VlcMediaPlayerLogEventArgs e)
        {
            string message = "libVlc : " + e.Level + e.Message + e.Module;
            System.Diagnostics.Debug.WriteLine(message);
            //System.Diagnostics.Trace.WriteLine(message);
            
        }

        private void imgClose_MouseDown(object sender, MouseButtonEventArgs e)
        {
            this.Close();
            Application.Current.Shutdown();

        }

        private void imgMin_MouseDown(object sender, MouseButtonEventArgs e)
        {
           // WindowStateUtil.FullOrMin(this, WindowState.Minimized);

        }
    }
}

3.3前端 只需添加 image组件即可

3.4最终效果：
