一个简单的直播 IOS客户端 + 服务端

IOS 端

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

man brew

Homebrew

Homebrew

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