Nginx及nginx-rtmp-module安裝

新建目錄

mkdir /usr/local/mginx

下載

cd /usr/local/nginx
wget http://nginx.org/download/nginx-1.12.2.tar.gz
wget https://codeload.github.com/arut/nginx-rtmp-module/zip/master

解壓

tar -zxvf nginx-1.12.2.tar.gz
unzip nginx-rtmp-module-master.zip 

安裝

nginx的一些模組依賴一些lib庫，在安裝nginx之前，須先安裝這些lib庫，

依賴庫主要有g++、gcc、openssl-devel、pcre-devel和zlib-devel 視情況執行如下命令安裝

yum install gcc-c++ 
yum install pcre pcre-devel  
yum install zlib zlib-devel 
yum install openssl openssl--devel 

cd /usr/local/nginx/nginx-1.12.2
#完成rtmp模組安裝
./configure --add-module=/usr/local/nginx/nginx-rtmp-module-master
make
make install

至此nginx及相關模組安裝完畢

配置及啟動服務支援rtmp

服務管理

cd /usr/local/nginx/sbin
nginx #啟動服務
nginx -s stop #管理服務

直播

利用ffmpeg進行推流直播

ffmpeg -re -i "E:\ffmpeg-20180227-fa0c9d6-win64-static\bin\1234.mp4" -acodec copy -vcodec copy -f flv -an  rtmp://192.168.174.200:1935/live/a 

利用vlc測試，地址：rtmp://192.168.174.200:1935/live/a

點播

將本地mp4檔案複製到/usr/local/nginx/html/hls

利用vlc測試：rtmp://192.168.174.200:1935/vod/1234.mp4

配置支援hls

工作流程

修改配置檔案

cd /usr/local/nginx/conf
vim mime.types

#在 application/zip zip; 這一行後面增加2行： 
application/x-mpegURL m3u8; 
application/vnd.apple.mpegurl m3u8;

vim video/x-msvideo
#avi;行後，增加1行：
video/MP2T ts;

點播

使用ffmpeg將mp4格式檔案轉成TS格式檔案

ffmpeg -y -i 1234.mp4 -vcodec copy -acodec copy -vbsf h264_mp4toannexb test.ts

使用ffmpeg將TS檔案切成ts分片併產生m3u8檔案

ffmpeg -i test.ts -c copy -map 0 -f segment -segment_list playlist.m3u8 -segment_time 2 test%03d.ts

將所得的ts分片和m3u8檔案放到nginx\html目錄下

vlc輸入[ http://192.168.174.200:80/playlist.m3u8 ]即可看到點播視訊 

注：192.168.174.200是本機的區域網ip，也即http伺服器的ip

直播

使用ffmpeg接收rtsp流並自動實時切片到http伺服器下

ffmpeg -i rtsp://admin:[email protected]/cam/realmonitor?channel=1&subtype=1 -c copy -vcodec h264 -f hls -hls_time 2.0 -hls_list_size 5 -hls_wrap 5 /usr/local/nginx/html/test.m3u8

vlc輸入[ http://172.19.12.240/test.m3u8 ]即可看到直播視訊

錄製

通過ffmpeg向伺服器推流，在伺服器進行視訊錄製

ffmpeg -re -i "E:\ffmpeg-20180227-fa0c9d6-win64-static\bin\1234.mp4" -acodec copy -vcodec copy -f flv -an  rtmp://192.168.174.200:1935/live/a

http://192.168.174.200/hls/a/index.m3u8

修改nginx.conf配置

rtmp {
    server {
	listen 1935;
	chunk_size 4096;

	application vod {
		play /usr/local/nginx/html/hls;
     	}

    	application live {
                live on;
	        hls on; #這個引數把直播伺服器改造成實時回放伺服器。
                wait_key on; #對視訊切片進行保護，這樣就不會產生馬賽克了。
                hls_path /usr/local/nginx/html/hls; #切片視訊檔案存放位置。
                hls_fragment 10s;     #每個視訊切片的時長。
                hls_playlist_length 60s;  #總共可以回看的事件，這裡設定的是1分鐘。
                hls_continuous on; #連續模式。
                hls_cleanup on;    #對多餘的切片進行刪除。
                hls_nested on;     #巢狀模式。
        }
    }
}

檢視已經產生切片視訊檔案了。其中還有一個index.m3u8。 

cd /usr/local/nginx/html/hls/a/
ls

vlc輸入[ http://192.168.174.200/hls/a/index.m3u8 ]即可看到視訊
