nginx + ffmpeg搭建音视频直播/点播系统

nginx

1. 配置

   rtmp {
          
       server {
          
           listen      1935;
           # 点播服务vod
           application svod {
          
               play /opt/video/vod;  #点播视频存放位置
           }
           application live {
          
               live on;
               meta copy;
               hls on;
               hls_path /home/neil/suheng/living/hls;
           }
       }
   }
   
   

2. ffempeg桌面视频录制

   ffmpeg -f x11grab -i :0.0 -vcodec libx264 -an desktop.mp4
   

3. ffempeg + rtmp 点播
   需要在nginx.conf增加对应的点播服务配置，服务根据application name作为路由，去访问设置的视频存储位置；配置好后reload nginx，然后访问对应路由即可播放点播视频
   

   如上点播服务名称为svod时，拉流访问地址为rtmp://localhost/svod/xxx.mp4;

4. ffmpege + rtmp直播

   ffmpeg -f v4l2 -i /dev/video0 -vcodec libx264 -an -f flv rtmp://localhost/live/demo （电脑摄像头设备作为输入）
   

   ffmpeg -stream-loop -1 -i /home/neil/suheng/living/hls/logo.mp4 -vcodec libx264 -an -f flv rtmp://192.168.118.131/live/demo（以本地视频无限循环作为直播流）
   

   使用vlc播放器或者ffplay访问网络流rtmp://localhost/live/demo可以接收直播流
