直播平臺大致流程
該圖片轉自其他網路
實時傳輸協議有：RTMP、HLS、HDL（HTTP-FLV）
編譯環境
apt-get install build-essential
nginx安裝
安裝pcre（目前最新8.44）
./configure make && make install pcre-config --version //查看版本
下載nginx-rtmp-module源
git 下載https://github.com/arut/nginx-rtmp-module
安裝nginx（目前最新1.17.9）
./configure --add-module=../nginx-rtmp-module --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/pcre-8.44 make make install
啟動nginx
./sbin/nginx -c /usr/local/nginx/conf/nginx.conf
obs studio視頻直播錄制軟體安裝（debian盡量9以上，因為ops有要求，不然自己編譯有點麻煩）
https://obsproject.com/download
ffmpeg轉碼安裝
https://obsproject.com/wiki/install-instructions#linux里有安裝流程
或者低版本的
sh -c 'echo "deb http://www.deb-multimedia.org jessie main" >> /etc/apt/sources.list' apt-get update apt-get install deb-multimedia-keyring apt-get install ffmpeg
rtmp引數配置
nginx.conf點播配置
#播放地址示例: rtmp://localhost/live/qq.mp4 rtmp { #RTMP服務 server { listen 1935; #//服務埠 chunk_size 4096; #//資料傳輸塊的大小 application live { play /usr/local/nginx/video; #//視頻檔案存放位置， } } }
nginx.conf直播配置

重啟nginx
sudo ./sbin/nginx -s reload
開啟 ffmpeg
ffmpeg -re -i /usr/local/nginx/video/test.mp4 -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -f flv rtmp://localhost/hls/stream
結果
http直接播放
