RTMP流媒体服务器

概念

我们在做直播，或者录播推送的时候，首先需要一个rtmp流媒体服务器。

参考：

• nginx-rtmp
• VideoJS Player

RTMP流媒体服务器搭建

docker-compose.yml

version: '3'
services:

  # 推流服务器
  nginx-rtmp:
    container_name: nginx-rtmp
    image: alfg/nginx-rtmp
    restart: always
    # ports:
    #   - "1935:1935"
    #   - "8080:80"
    ports:
      - "40001:1935"
      - "40002:80"
    volumes:
      - ./nginx:/opt/nginx

推流测试

# 推流方式一（HLS）
ffmpeg -re -i video.mp4 -s 1280x720 -c copy -f flv "rtmp://114.67.69.231:40001/stream/test"
http://114.67.69.231:40002/live/test.m3u8

# 推流方式二（RTMP）
ffmpeg -re -i video.mp4 -s 1280x720 -c copy -f flv "rtmp://114.67.69.231:40001/live/test"
rtmp://114.67.69.231:40001/live/test

Nginx配置示例
