HLTML5播放HLS流(.m3u8文件)跨域访问

我用ckplayer播放器实现在HTML5环境中播放.m3u8文件时出现No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

在网上查找说需要在网站根目录下添加crossdomain.xml文件，我也添加了，结果还是无效。最后摸索了半天才找到了如下解决方案(不需要添加crossdomain.xml文件)

修改nginx.conf
修改nginx.conf，在location /hls模块下添加

add_header Access-Control-Allow-Origin *;

我的nginx配置如下:

rtmp {

        server {

            listen 1935;  #监听的服务端口

            chunk_size 4096; #数据传输块的大小

            #设置直播的application名称是hls

            application hls {  
                live on;
                hls on;
                hls_path /home/wwwroot/hls;
                hls_fragment 5s;
            }
        }
}

http{
    server {
        listen       80;
        server_name  www.vmliveroom.io vmliveroom.io;

        root    "/home/wwwroot/liveroom/public";
        include /usr/local/nginx/conf/enable-php-pathinfo.conf;
        location / {
            index  index.html index.htm index.php l.php;
            autoindex  off;

            if (!-e $request_filename) {
            rewrite  ^(.*)$  /index.php?s=/$1  last;
            }
        }

        location /hls {
            # Serve HLS fragments
            types {
                application/vnd.apple.mpegurl m3u8;
                video/mp2t ts;
            }
            root /home/wwwroot;
            add_header Cache-Control no-cache;
            #添加下面一行
            add_header Access-Control-Allow-Origin *;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}
