jw player+nginx搭配流媒体播放器

环境：centos 6.5 64位+php 5.3.28+nginx 1.29

1.编译安装nginx时加上--with-http_mp4_module --with-http_flv_module这两个参数，开启FLV MP4支持

2.修改nginx配置文件

vi /usr/local/nginx/conf/nginx.conf

server
        {
                listen       80;
                server_name www.abc.com abc.com;
                index index.html index.htm index.php;
                root  /home/www/html;
                limit_rate_after 5m;
                limit_rate 512k;
                location ~ .*.(php|php5)?$
                        {
                                try_files $uri =404;
                                fastcgi_pass  unix:/tmp/php-cgi.sock;
                                fastcgi_index index.php;
                                include fcgi.conf;
                        }
               
                location ~ .*.flv
                {
                        flv;
                }
                location ~ .*.mp4
                {
                        mp4;
                        mp4_buffer_size 1m;
                        mp4_max_buffer_size 5m;

　　　　　　}
                location /status {
                        stub_status on;
                        access_log   off;
                }

                location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$
                        {
                                expires      30d;
                        }

                location ~ .*.(js|css)?$
                        {
                                expires      12h;
                        }
                error_page 404  /404.html;

｝

安装yamdi，对视频添加关键帧，添加完后可以拖动进度

yum -y install yamdi

使用方法：

yamdi -i 2.flv -o 4.flv  #-i 是输入文件 -o是输出文件

设置jw player的相关参数，这里只设置了一部分，需要了解详细参数的请google

页面HTML代码：

<div id="mediaspace">正在加载视频……</div>

<div id="playerConfig"></div>
<div id="timex" style="display:none;"></div>
<div id="buffer"></div>

<div id="volume"></div>

<script type='text/javascript'>

  var cur_time = 0; //当前播放时间

  var videoId = 1;//视频id，用来做cookie唯一
  var strCookie = document.cookie; //获取当前COOKIE

  if(strCookie.indexOf('video_'+videoId+'=')!=-1){  //如果有记录上次播放时间，从上次记录的时间开始播放
      start_time = getCookie('video_'+videoId,strCookie); //获取上次播放时间
  }
