Mac下通过FFMpeg实现Android手机推流和播放

一、Mac下搭建推流服务器（Nginx+RTMP+FFMpeg）

安装x264

git clone git://git.videolan.org/x264.git
cd x264
./configure --enable-static --enable-shared
make -j8
sudo make install

安装FFMpeg

git clone git://source.ffmpeg.org/ffmpeg.git
cd ffmpeg

./configure --enable-gpl --enable-nonfree --enable-pthreads --enable-libx264 --enable-libmp3lame
make -j8
sudo make install

FFMpeg源码Xcode debug

安装Nginx和nginx_rtmp_module插件

git clone https://github.com/nginx/nginx.git
git clone https://github.com/arut/nginx-rtmp-module.git
cd nginx-v.XXX
./configure --add-module=/path/to/nginx-rtmp-module --with-openssl=/path/to/openssl-v.XXX
make -j8
make install

 安装VCL

http://get.videolan.org/vlc/3.0.1/macosx/vlc-3.0.1.dmg

 配置RTMP Server文件，nginx.conf

rtmp {
    server {
        # 监听端口
        listen 1935; 
        chunk_size 4000;

        application rtmplive {
           live on;
           max_connections 1024;
        }
    }
}

执行 推流命令播放视频

ffmpeg -re -i ~/Desktop/XXXX.mov -c copy -f flv rtmp://localhost:1935/rtmplive/home

执行 推流命令打开本地摄像头

ffmpeg -f avfoundation -framerate 30 -video_size 1280x720 -i "0:0" -vcodec libx264 -preset ultrafast -acodec libmp3lame -ar 44100 -ac 1 -f flv rtmp://localhost:1935/rtmplive/home

 执行 播放

ffplay rtmp://localhost:1935/rtmplive/home

 VLC File->OpenNetwork

rtmp://localhost:1935/rtmplive/home

nginx

# nginx   // 启动
# nginx -s stop   // 关闭
# lsof -i:8080    // 查看端口占用

error,  端口小于1024的需要root权限，要么提权，要么该端口

nginx: [emerg] bind() to 0.0.0.0:80 failed (13: Permission denied)

he socket API bind() to a port less than 1024, such as 80 as your title mentioned, need root access.
here is "Bind to ports less than 1024 without root access"
and another easier way is to run nginx as root.
