Windows下通过nginx将摄像头RTSP视频流转为HLS格式

安装

首先Nginx安装配置请参考，本文不再赘述：

Windows下通过nginx将摄像头RTSP视频流转为RTMP格式

nginx-rtmp新建hls

整个服务部署文件构架如下

nginx-rtmp
│ nginx.exe
│
├─conf
│ fastcgi.conf
│ fastcgi_params
│ koi-utf
│ koi-win
│ mime.types
│ nginx.conf
│ scgi_params
│ uwsgi_params
│ win-utf
│
├─hls
│
├─html
│ 50x.html
│ index.html
│ stat.xsl
│
├─logs
│
└─temp

配置conf/nginx.conf文件

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  4096;
}

# 添加RTMP服务

启动

start nginx

通过海康威视综合安防管理平台的API接口返回的RTSP流为：

rtsp://IP地址:554/openUrl/rby3v0s?beginTime=20201219T234629&endTime=20201220T001459&playBackMode=1&streamform=rtp

打开CMD，执行命令

ffmpeg  -re -rtsp_transport tcp -i rtsp://IP地址:554/openUrl/rby3v0s?beginTime=20201219T234629^&endTime=20201220T001459^&playBackMode=1^&streamform=rtp -f flv -vcodec libx264 -vprofile baseline -acodec aac -ar 44100 -strict -2 -ac 1 -s 800x600 -q 10 rtmp://localhost:1935/hls/movie

ffmpeg拉rtsp流实现文件的分片，并生成m3u8

VLC取流： http://localhost:8080/hls/movie/index.m3u8
