Docker - NGINX MEDIA SERVER 만들기

 

그냥 아래 파일을 주로 이용했었음. 개발용으로...

    hub.docker.com/r/tiangolo/nginx-rtmp/

    github.com/tiangolo/nginx-rtmp-docker/blob/master/Dockerfile

buildpack-deps:stretch를 기본 이미지로 사용했는데, 이미지 크기가 약 850MB임.

배포 이미지에 HLS, DASH가 비활성화 되어 있어서 필요할 경우 새로 빌드해야 했는데,

용량도 줄이고 옵션도 켜고 .. 나만의 이미지(?)를 만들기로 함. 

 

TL; DR

nginx-media-server : RTMP push스트림을 받아 RTMP/HLS/DASH 서빙.

    github.com/woonizzooni/nginx-media-server

 

• 서버 실행

$ docker run -d -p 1935:1935 -p 8080:8080 --name nginx-media-server woonizzooni/nginx-media-server:latest

 

• RTMP 송출  (Windows / MacOS / 공통) : Stream key를 'test'로 함.

> Example
$ ffmpeg -f avfoundation -i "1:0" \
    -c:v libx264 -deinterlace -r 24 -s 1280x720 \
      -b:v 1200k -minrate 1200k -maxrate 1200k -bufsize 1200k -pix_fmt yuv420p \
      -profile:v baseline -x264-params keyint=48:keyint_min=24:scenecut=0:bframes=0 \
    -c:a libfdk_aac -b:a 128k -ar 44100 \
    -f flv "rtmp://localhost/live/test"

• HLS/DASH 지원 플레이어로 아래 URL 재생
  HLS : http://localhost:8080/hls/test/index.m3u8
  DASH: http://localhost:8080/dash/test/index.m3u8
