ffmpeg+HLS实现直播与回放

Nginx配置视频服务器

 server
  {
     listen ;
     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 -;
            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 gitgit clone https://github.com/arut/nginx-rtmp-module.git  

2下载编译nginx

yum -y install pcre-devel openssl openssl-devel 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 8;

events {
worker_connections 1024;
}
rtmp {

server {

listen 28011;
chunk_size 4000;
# TV mode: one publisher, many subscribers
application mylive {
# enable live streaming
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 28012;
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;
}
