ffmpeg+HLS实现直播与回放

Nginx配置视频服务器

 server
  {
     listen 28024;
     server_name localhost;
   location /hls{
     add_header Access-Control-Allow-Origin *;
     add_header Access-Control-Allow-Headers X-Requested-With;
     add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
             types{
                 application/vnd.apple.mpegurl m3u8;
                 video/mp2t ts;
            }
            alias /data/hls;
            expires -1;
            add_header Cache-Control no-cache;
        }
    access_log off;
  }
}

FFmpeg拉流转码

ffmpeg -re  -rtsp_transport tcp -i 'rtsp://{IP}:9090/dss/monitor/params?cameraid={设备ID}${管道}&substream={码流}' \
　　　　　　　　-c copy -map 0 -f segment -segment_list /data/hlstest.m3u8 -segment_list_flags +live -segment_time 10 -hls_list_size 20 /data/hls/output%03d.ts

-segment_list 配置输出的列表文件名
-segment_time 切片时长
-hls_list_size 保存最后切片数量

FFmpeg拉流推送HLS服务

ffmpeg -re  -rtsp_transport tcp -i 'rtsp://112.85.138.10:9090/dss/monitor/params?cameraid=1000401$0&substream=1' \
            -vcodec copy  -vprofile baseline  -f flv -s 1280x720 -segment_list_flags +live -segment_time 10 -hls_list_size 20 'rtmp://192.168.200.31:28099/hls/test2'

-segment_list 配置输出的列表文件名
-segment_time 切片时长
-hls_list_size 保存最后切片数量

HLS服务Nginx服务器

1下载nginx-rtmp-module

yum install git

git clone https://github.com/arut/nginx-rtmp-module.git  

2下载编译nginx

yum -y install pcre-devel
yum -y install openssl openssl-devel
yum install gcc gcc-c++ 
wget http://nginx.org/download/nginx-1.8.1.tar.gz  
tar -zxvf nginx-1.8.1.tar.gz  
cd nginx-1.8.1  
./configure --prefix=/usr/local/nginx  --add-module=../nginx-rtmp-module  --with-http_ssl_module    
make && make install  

3修改nginx.conf

worker_processes  1;

events {
    worker_connections  1024;
}
rtmp {
    server {
       listen 28099;
       chunk_size 4000;
       application mylive {
            live on;
        }
　　　　application hls {
　　　　live on;
　　　　hls on;
　　　　hls_path /data/hls;
　　　　hls_fragment 5s;
　　　　}
    }
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;

   server {
    listen 28023;
    server_name localhost;
    location /hls{
　　　　add_header Access-Control-Allow-Origin *;
  　　　add_header Access-Control-Allow-Headers X-Requested-With;
  　　　add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
            types{
                 application/vnd.apple.mpegurl m3u8;
                 video/mp2t ts;
            }
            alias /data/hls;
            expires -1;
            add_header Cache-Control no-cache;
        }
 }
}
