[Nginx] RTMP module 설치 및 설정

1.설치

NGINX 소스와 rmtp모듈 소스 다운로드

wget http://nginx.org/download/nginx-1.7.5.tar.gz
wget https://github.com/arut/nginx-rtmp-module/archive/master.zip

파일 압축 해제

tar -zxvf nginx-1.7.5.tar.gz
unzip master.zip

NGINX 소스 디렉토리로 이동후 

./configure --add-module=/path/to/nginx-rtmp-module
make
make install

nginx (1.3.14 -1.5.0) 버전은 http_ssl_module 를 추가로 설치하여하야합니다.

./configure --add-module=/path/to/nginx-rtmp-module --with-http_ssl_module

디버그 버전을 빌드하기 위한 추가설정

./configure --add-module=/path/to-nginx/rtmp-module --with-debug

RTMP URL format

rtmp://rtmp.example.com/app/[/name]

app - 설정파일의 하나의 application 이름과 같아야합니다.

name - 없어도 되지만 설정하게 되면 개별의 방송을 할 수 있습니다. ( 방개념이라 생각하면 쉬울 것 같습니다,)

2. NGINX CONFIG 파일 설정

설정 파일은 보통 /usr/local/nginx/nginx/conf/nginx.conf 또는 /etc/nginx/nginx.conf 에 있습니다.

아래는 예시 이므로 골라서 사용하면 됩니다.

            #
            # ffmpeg can do anything with the stream like video/audio
            # transcoding, resizing, altering container/codec params etc
            #
            # Multiple exec lines can be specified.

        # HLS

        # For HLS to work please create a directory in tmpfs (/tmp/hls here)
        # for the fragments. The directory contents is served via HTTP (see
        # http{} section in config)
        #
        # Incoming stream must be in H264/AAC. For iPhones use baseline H264
        # profile (see ffmpeg example).
        # This example creates RTMP stream from movie ready for HLS:
        #
        # ffmpeg -loglevel verbose -re -i movie.avi  -vcodec libx264
        #    -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1
        #    -f flv rtmp://localhost:1935/hls/movie
        #
        # If you need to transcode live stream use 'exec' feature.
        #
        application hls {
            live on;
            hls on;

        }

        # MPEG-DASH is similar to HLS

        application dash {
            live on;
            dash on;
            dash_path /tmp/dash;
