一个简单的直播 rtmp

IOS 端

LFLiveKit

LaiFengiOS/LFLiveKit

private let streamUrl = "rtmp://192.168.1.113:1935/rtmplive/test"

lazy var session: LFLiveSession = {
    let audioConfiguration = LFLiveAudioConfiguration.default()
    let videoConfiguration = LFLiveVideoConfiguration.defaultConfiguration(for: LFLiveVideoQuality.low3, outputImageOrientation: UIInterfaceOrientation.portrait)
    
    let session = LFLiveSession(audioConfiguration: audioConfiguration, videoConfiguration: videoConfiguration)
    
    session?.delegate = self
    session?.preView = self.view
    session?.running = true
    return session!
}()
func startLive() -> Void {
    let stream = LFLiveStreamInfo()
    stream.url = streamUrl
    session.startLive(stream)
}
func stopLive() -> Void {
    session.stopLive()
}

IJKFramework

let urlStr = "rtmp://192.168.1.113:1935/rtmplive/test"
let options = IJKFFOptions.byDefault()

IJKFFMoviePlayerController.setLogReport(false)
IJKFFMoviePlayerController.setLogLevel(k_IJK_LOG_ERROR)
IJKFFMoviePlayerController.checkIfFFmpegVersionMatch(true)

moviePlayerController = IJKFFMoviePlayerController(contentURLString: urlStr, with: options)
moviePlayerController.view.autoresizingMask = [UIViewAutoresizing.flexibleWidth, .flexibleHeight]
moviePlayerController.view.frame = UIScreen.main.bounds
moviePlayerController.scalingMode = IJKMPMovieScalingMode.aspectFit
moviePlayerController.shouldAutoplay = true
self.view.addSubview(moviePlayerController.view)
moviePlayerController.prepareToPlay()
moviePlayerController.play()

Mac搭建nginx+rtmp服务器

Homebrew

终端运行 man brew 查询是否安装 Homebrew

• Homebrew 安装 ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

• Homebrew 卸载 ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

Nginx

• clone Nginx 项目到本地 brew tap homebrew/nginx

• 安装 brew install nginx-full --with-rtmp-module

• 测试 输入nginx 在浏览器打开 http://localhost:8080 能正常访问表示安装成功

• 查看 输入 brew info nginx-full 在输出信息中我找到

==> Caveats Docroot is: /usr/local/var/www

The default port has been set in /usr/local/etc/nginx/nginx.conf to 8080 so that nginx can run without sudo.

nginx will load all files in /usr/local/etc/nginx/servers/.

• 编辑 nginx.conf 添加 RTMP 配置

# 在http节点后面加上rtmp配置：
rtmp {
  	server {
      	listen 1935;


    	#直播流配置
      	application rtmplive {
          	live on;
      		#为 rtmp 引擎设置最大连接数。默认为 off
      		max_connections 1024;
		}
    
    	application hls{
        	live on;
          	hls on;
          	hls_path /usr/local/var/www/hls;
          	hls_fragment 1s;
      	}
   	}
}

• 重启 Nginx /usr/local/Cellar/nginx-full/1.12.2/bin/nginx -s reload 或者 nginx -s reload nginx -s stop // 停止 nginx -s quit // 退出

FFmpeg

• 安装 brew install ffmpeg

使用 FFmpeg 推流

推流拉流同时进行

• 推流 MOV 视频文件 ffmpeg -re -i /Users/syc/Desktop/test.MOV -vcodec libx264 -acodec aac -strict -2 -f flv rtmp://localhost:1935/rtmplive/test

• 推流 桌面(桌面分享) ffmpeg -f avfoundation -i "1" -vcodec libx264 -preset ultrafast -acodec libfaac -f flv rtmp://localhost:1935/rtmplive/test

• 推流 桌面+麦克风 ffmpeg -f avfoundation -i "1:0" -vcodec libx264 -preset ultrafast -acodec libmp3lame -ar 44100 -ac 1 -f flv rtmp://localhost:1935/rtmplive/test

• 推流 桌面+麦克风+摄像头 ffmpeg -f avfoundation -framerate 30 -i "1:0" \-f avfoundation -framerate 30 -video_size 640x480 -i "0" \-c:v libx264 -preset ultrafast \-filter_complex 'overlay=main_w-overlay_w-10:main_h-overlay_h-10' -acodec libmp3lame -ar 44100 -ac 1 -f flv rtmp://localhost:1935/rtmplive/test

使用 VLC 拉流播放

Open Network 打开 rtmp://localhost:1935/rtmplive/test
