Ubuntu12.04.3 配置nginx-rtmp支持HLS

来源：互联网发布：下载淘宝帐号注册账号编辑：程序博客网时间：2024/04/30 14:10

之前编译配置过 ngix-rtmp 来支持HLS.

linux和windows都有。 http://blog.csdn.net/commshare/article/details/17652171

今天需要测试下HLS，捣鼓了下http 服务器，发送HFS有问题啊，经常不重启不能工作。

于是换用linux下的nginx-rtmp。

发现需要重新配置下，才能让nginx-rtmp工作。

nginx-rtmp 的可执行文件的路径：

sbin中是带有rtmp模块的nginx 。

conf中是配置文件。

./nginx 就可以启动nginx，没有任何输出。

之前不知道，还以为是其他的服务器占用了这个端口呢：

root@Ubuntu32:/home/zhangbin/streaming/hls/nginx-rtmp/home/sbin# ./nginx
nginx: [emerg] bind() to 0.0.0.0:1935 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8080 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:1935 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8080 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:1935 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8080 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:1935 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8080 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:1935 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8080 failed (98: Address already in use)
nginx: [emerg] still could not bind()

寻找80端口：

root@Ubuntu32:/home/zhangbin/streaming/hls/nginx-rtmp/home/sbin# sudo netstat -pan | grep ":80"tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 6048/nginx tcp 1 0 192.168.1.88:47676 91.189.94.25:80 CLOSE_WAIT 2805/ubuntu-geoip-ptcp6 0 0 :::80 :::* LISTEN 1343/apache2

发现就是nginx占用了8080.

apache2应该用的是80

root@Ubuntu32:/home/zhangbin/streaming/hls/nginx-rtmp/home/sbin# ./nginx -hnginx version: nginx/1.4.3Usage: nginx [-?hvVtq] [-s signal] [-c filename] [-p prefix] [-g directives]Options: -?,-h : this help -v : show version and exit -V : show version and configure options then exit -t : test configuration and exit -q : suppress non-error messages during configuration testing -s signal : send signal to a master process: stop, quit, reopen, reload -p prefix : set prefix path (default: /home/zhangbin/streaming/hls/nginx-rtmp/home/) -c filename : set configuration file (default: conf/nginx.conf) -g directives : set global directives out of configuration file修改以下的hls_path:

  application hls {             live on;             hls on;             #hls_path /srv/nginxhls/app;     hls_path /home/zhangbin/alex/Downloads/testVideos;             hls_fragment 5s;       }

路径 /hls是指在浏览器或者播放器的 url中加入/hls，这里alias是定向到磁盘的实际路径。

        location /hls {           #server hls fragments           types{             application/vnd.apple.mpegurl m3u8;             video/mp2t ts;           }        alias /home/zhangbin/alex/Downloads/testVideos;        #/srv/nginxhls/app;        expires -1;        }

修改后有俩错误，主要是没有加上；导致的：
root@Ubuntu32:/home/zhangbin/streaming/hls/nginx-rtmp/home/sbin# ./nginx -s reload
nginx: [emerg] invalid number of arguments in "hls_path" directive in /home/zhangbin/streaming/hls/nginx-rtmp/home/conf/nginx.conf:40

nginx: [emerg] invalid number of arguments in "alias" directive in /home/zhangbin/streaming/hls/nginx-rtmp/home/conf/nginx.conf:88

我最后的配置文件：

#user  nobody;worker_processes  1;#error_log  logs/error.log;#error_log  logs/error.log  notice;#error_log  logs/error.log  info;#pid        logs/nginx.pid;events {    worker_connections  1024;}rtmp {    server {        listen 1935;        application myapp {            live on;            #record keyframes;            #record_path /tmp;            #record_max_size 128K;            #record_interval 30s;            #record_suffix .this.is.flv;            #on_publish http://localhost:8080/publish;            #on_play http://localhost:8080/play;            #on_record_done http://localhost:8080/record_done;       }       application hls {             live on;             hls on;             #hls_path /srv/nginxhls/app;     hls_path /home/zhangbin/alex/Downloads/testVideos;             hls_fragment 5s;       }    }}http {    server {        listen      8080;        location /stat {            rtmp_stat all;            rtmp_stat_stylesheet stat.xsl;        }        location /stat.xsl {            root <path-to-nginx-rtmp-module>;        }        location /control {            rtmp_control all;        }        #location /publish {        #    return 201;        #}        #location /play {        #    return 202;        #}        #location /record_done {        #    return 203;        #}        location /rtmp-publisher {            root <path-to-nginx-rtmp-module>/test;        }        location /hls {           #server hls fragments           types{             application/vnd.apple.mpegurl m3u8;             video/mp2t ts;           }        alias /home/zhangbin/alex/Downloads/testVideos;        #/srv/nginxhls/app;        expires -1;        }        location / {            root <path-to-nginx-rtmp-module>/test/rtmp-publisher;        }    }}

重启：

root@Ubuntu32:/home/zhangbin/streaming/hls/nginx-rtmp/home/sbin#./nginx -s reload

浏览器并不直接支持m3u8和MP4：

用播放器吧：
