直播流

1. 安装nginx 和 rtmp 模块以及 ffmpeg

sudo apt install nginx  libnginx-mod-rtmp ffmpeg

2. 配置nginx

vi /etc/nginx/nginx.conf
#加入
rtmp {
 
    server {
 
        listen 1935;
 
        chunk_size 4000;
 
        # TV mode: one publisher, many subscribers
        application mylive {            ####视频输出流 url 路径必须是  /mylive/... 
 
            # enable live streaming
            live on;
 
        }
    }
}

3. ffmpeg转码

ffmpeg -i "rtsp://admin:admin12345@192.168.0.110:554/user=admin&password=admin12345&channel=1&stream=0.sdp?real_stream"  -b 4096k -f flv -r 25 -s 1920x1080 -an "rtmp://172.20.10.2:1935/mylive/robit"

# 注意输出路径必须时 /mylive/ 否则会报错

4. 监控rtmp 流
