# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

5. nginx 도 풀고
tar -zxvf nginx-1.7.5.tar.gz
6. nginx 폴더에서 rtmp 모듈 추가
./configure --add-module=/path/to-nginx/rtmp-module --with-debug --with-http_ssl_module
7. gcc가 없다면 (그리고 다시6)
yum install gcc
8. error 라면
./configure: error: the HTTP rewrite module requires the PCRE library.
yum -y install pcre-devel
9.제길 귀찮다 . 개발 툴 다 설치하자.
# yum groupinstall "Development Tools"
# yum install pcre-devel openssl-devel libxslt-devel gd-devel perl-ExtUtils-Embed epel-release
# yum install GeoIP-devel
10.그리고 다시6

13. RTMP URL format
rtmp://rtmp.example.com/app/[/name]
app - 설정파일의 하나의 application 이름과 같아야 한덴다.
name - 설정하게 되면 개별의 방송을 할 수 있습니다. ( 방개념이란다) streamkey이기도하다.
14.ffmpeg도 해두자 .영상 저장 혹은 로컬 영상 배포용이다.
yum install ffmpeg
15. 이제 nginx에 rtmp 포트및 기타 설정하자.
심플한 사용방법은 이렇다
....
rtmp {
server {
listen 1935; # Listen on standard RTMP port
chunk_size 4000;
application show {
live on;
allow publish all;
# # Turn on HLS
hls on;
hls_path /mnt/hls/;
hls_fragment 3;
hls_playlist_length 60;
# # disable consuming the stream from nginx as rtmp
# deny play all;
}
}
}
http{
...
-일단 간단하게 서버의 파일을 스트리밍 하는걸로 해보자 ffmpeg가 짱이다.
wget https://file-examples-com.github.io/uploads/2017/04/file_example_MP4_640_3MG.mp4
ffmpeg -re -i example-vid.mp4 -vcodec libx264 -vprofile baseline -g 30 -acodec aac -strict -2 -f flv rtmp://너의서버아이피겠쥐?/show/stream
하고 나서 obs나 rtmp뷰어 앱 등에서 확인하면 잘 돌아가는걸 볼수 잇다.
또한 OBS 나 rtmp 배신 프로그램이 있다면 그걸 이용해서 실시간 방송도 할수 있다.
OBS라면 settting->Stream->Service[custom]->Server[ rtmp://너의아이피/nginx에서 설정한application이름/스트리밍할때지정한키(또는룸이름)]
으로 지정하고 Start streaming 하면 방송이 되고 또 그걸 rtmp뷰어앱등에서 실시간으로 영상이 보인다.
rtmp {
server {
listen 1935;
chunk_size 4000;
# TV mode: one publisher, many subscribers
application mytv {
# enable live streaming
live on;
# record first 1K of stream
record all;
record_path /tmp/av;
record_max_size 1K;
# append current timestamp to each flv
record_unique on;
# publish only from localhost
allow publish 127.0.0.1;
deny publish all;
#allow play all;
}
# Transcoding (ffmpeg needed)
application big {
live on;
# On every pusblished stream run this command (ffmpeg)
# with substitutions: $app/${app}, $name/${name} for application & stream name.
#
# This ffmpeg call receives stream from this application &
# reduces the resolution down to 32x32. The stream is the published to
# 'small' application (see below) under the same name.
#
# ffmpeg can do anything with the stream like video/audio
# transcoding, resizing, altering container/codec params etc
#
# Multiple exec lines can be specified.

# The following notifications receive all
# the session variables as well as
# particular call arguments in HTTP POST
# request
# Make HTTP request & use HTTP retcode
# to decide whether to allow publishing
# from this connection or not
on_publish http://localhost:8080/publish;
# Same with playing
on_play http://localhost:8080/play;
# Publish/play end (repeats on disconnect)
on_done http://localhost:8080/done;
# All above mentioned notifications receive
# standard connect() arguments as well as
# play/publish ones. If any arguments are sent
# with GET-style syntax to play & publish
# these are also included.
# Example URL:
# rtmp://localhost/myapp/mystream?a=b&c=d
# record 10 video keyframes (no audio) every 2 minutes
record keyframes;
record_path /tmp/vc;
record_max_frames 10;
record_interval 2m;
# Async notify about an flv recorded
on_record_done http://localhost:8080/record_done;
}
# 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;
hls_path /tmp/hls;
}
# MPEG-DASH is similar to HLS
application dash {
live on;
dash on;
dash_path /tmp/dash;
}
}
