让nginx支持HLS

准备工作：

1.安装nginx和rtmp模块

2.安装ffmepg（用来推流）

以上准备工作参见这篇博客：http://www.cnblogs.com/damiao/p/5231221.html

1.配置nginx

用记事本工具打开

/usr/local/etc/nginx/nginx.conf

找到server 修改

 server {
        listen       8080;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }

        location /hls {
            # Serve HLS fragments
            types {
                application/vnd.apple.mpegurl m3u8;
                video/mp2t ts;
            }
            root html;
            add_header Cache-Control no-cache;
        }

        location /dash {
            # Serve DASH fragments
            root /tmp;
            add_header Cache-Control no-cache;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }

找到rtmp 修改下面这个地方

rtmp {
    server {
        listen 1935;
        application live1 {
            live on;
            record off;
        }

        # HLS

        # For HLS to work please create a directory in tmpfs (/tmp/hls here)
        # for the fragments. The directory contents is served via HTTP (see
        # http{} section in config)
        #
        # Incoming stream must be in H264/AAC. For iPhones use baseline H264
        # profile (see ffmpeg example).
        # This example creates RTMP stream from movie ready for HLS:
        #
        # ffmpeg -loglevel verbose -re -i movie.avi  -vcodec libx264
        #    -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1
        #    -f flv rtmp://localhost:1935/hls/movie
        #
        # If you need to transcode live stream use 'exec' feature.
        #
        application hls {
            live on;
            hls on;
            hls_path /usr/local/var/www/hls;
        }

        # MPEG-DASH is similar to HLS

        application dash {
            live on;
            dash on;
            dash_path /tmp/dash;
        }
    }
 }

保存配置文件，重新加载nginx配置

/usr/local/Cellar/nginx-full/1.8.1/bin/nginx -s reload

2.进行推流

ffmpeg -loglevel verbose -re -i /Users/Rick/Movies/Demo.mov  -vcodec libx264 -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1 -f flv rtmp://localhost:1935/hls/movie

然后你就可以在这个目录

/usr/local/var/www/hls

看到生成一个个ts的文件，还会生成一个movie.m3u8的文件

在Safari里输入地址查看视频（需要等movie.m3u8文件生成后），也可以用iPad或者iPhone上的Safari来访问（其他设备记得需要把localhost改为nginx的ip地址）

http://localhost:8080/hls/movie.m3u8
