Http媒体流服务器

Question

我已经用RED5媒体服务器(RTMP)开发了视频流应用程序。而不是RTMP需要通过HTTP直播视频。

是否有开源的HTTP媒体服务器？？

有没有同时支持RTMP和HTTP的开源服务器？

提前谢谢。

Answer 1

HTTP和RTMP基本上是不同的协议。您将不会在HTTP中提供RTMP。(尽管您可以为隧道解决方案执行此操作)。

有几种方法可以实现HTTP流。例如HLS、DASH、平滑和渐进式下载。如果你需要服务流到iOS (iPad，iPhone，苹果电视)，你将需要使用HLS。

正如arcyqwerty所说的那样。任何HTTP服务器都能够提供HTTP流服务。但在提供服务之前，您需要准备您的媒体文件和清单文件。

对于阅读HLS (HTTP Live Streaming)，以下是一些非常重要的链接：

• https://developer.apple.com/library/ios/documentation/networkinginternet/conceptual/streamingmediaguide/Introduction/Introduction.html

• https://developer.apple.com/streaming/

• http://features.encoding.com/http-live-streaming-hls/

• https://datatracker.ietf.org/doc/html/draft-pantos-http-live-streaming-12

那么开源服务器呢？我知道这些：

http://www.flumotion.net/：

• Flumotion

• Gstreamer服务器流：http://cgit.freedesktop.org/gstreamer/gst-streaming-server/

• Nginx HLS模块：http://nginx.org/en/docs/http/ngx_http_hls_module.html (仅限Nginx Plus)

或者您可以像我一样，使用GStreamer进行细分和显示。最后，我只使用Nginx来为他们服务。

我希望我对你有一点帮助。

Answer 2

任何可以提供文件服务的HTTP服务器(apache、nginx、IIS等)都可以通过HTTP“流式传输”媒体。因此，如果你愿意，你可以保留RTMP的RED5，并设置一个超文本传输协议服务器来服务相同的文件。

您可能希望在Media streaming basics - HTTP vs RTMP中查找有关协议的信息

如果您需要一个单一产品的解决方案，那么将nginx-rtmp模块添加到nginx中可能就是您想要的

Answer 3

我使用它，它工作正常。(Ubuntu 12.04 TLS服务器)

分步执行：

sudo apt-get install build-essential libpcre3 libpcre3-dev libssl-dev
wget http://nginx.org/download/nginx-1.6.0.tar.gz
wget https://github.com/arut/nginx-rtmp-module/archive/master.zip
tar -zxvf nginx-1.6.0.tar.gz
unzip master.zip
cd nginx-1.6.0

./configure --with-http_ssl_module --add-module=../nginx-rtmp-module-master --with-http_flv_module --with-http_mp4_module
make
sudo make install

sudo /usr/local/nginx/sbin/nginx -s stop
sudo /usr/local/nginx/sbin/nginx

本地nginx配置：(/usr//nginx/conf/nginx.conf)

#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;

rtmp {
    server {
    listen 1935;
    chunk_size 4000;
    # video on demand for flv files
    application vod {
        play /var/flvs;
    }

    # video on demand for mp4 files
        application vod2 {
        play /var/mp4s;
        }
    }
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;

        # This URL provides RTMP statistics in XML
        location /stat {
            rtmp_stat all;
            rtmp_stat_stylesheet stat.xsl;
        }

        location /stat.xsl {
            # XML stylesheet to view RTMP stats.
            # Copy stat.xsl wherever you want
            # and put the full directory path here
            root /var/www/;
        }

    location /hls {
        # Serve HLS fragments
        types {
            application/vnd.apple.mpegurl m3u8;
            video/mp2t ts;
        }
        alias /tmp/app;
        expires -1;
    }

#   location /hds {
#       f4f;    # Use the HDS handler to manage requests
#           # serve content from the following location
#       alias /var/www/video;
#   }

    location /video {
        mp4;
        flv;
        mp4_buffer_size     4M;
        mp4_max_buffer_size 10M;
    }

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

    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;
    #}
    }
}

保存配置文件并执行以下操作：

sudo /usr/local/nginx/sbin/nginx -s stop
sudo /usr/local/nginx/sbin/nginx

接下来..。创建两个目录：

mkdir /var/flvs
mkdir /var/mp4s

您需要将一个mp4文件复制到mp4s目录。例如: sample.mp4

最终

sudo /usr/local/nginx/sbin/nginx -s stop
sudo /usr/local/nginx/sbin/nginx

尝试：

rtmp://your_server_ip/vod2/sample.mp4

(建议:使用VLC媒体播放器)
