RTMP NGINX 라이브 스트리밍 서버 - FreeBSD

❚ 개요

캡처도구 ---> OBS 송출 ---> (rtmp)서버(hls) ---> WEB <--- video TAG

 

❚ ffmpeg 설치

cd /usr/ports/multimedia/ffmpeg

make config

make BATCH=yes install clean

시간이 꽤 걸린다.

디스크에 여유 공간이 20GB 가량 있어야 한다.

설치를 마치면 점검한다.

ffmpeg -codecs
ffmpeg -formats
ffmpeg -i test.mp4 test.avi

 

❚ nginx 설치

cd /usr/ports/www/nginx
make config

RTMP를 스페이스바 키로 선택한다.

make BATCH=yes install clean
rehash

mkdir /usr/local/www/live
chown www:www /usr/local/www/live/
