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流式传输实时视频。

任何开源HTTP媒体服务器？？

是否有同时支持RTMP和HTTP的开源服务器？

提前谢谢。

Answer 1

HTTP和RTMP主要是不同的协议。您不会在HTTP中提供RTMP。（尽管您可以为隧道解决方案执行此操作）。

有几种方法可以进行HTTP流式传输。如HLS、DASH、Smooth和Progresive下载。如果您需要向iOS（iPad、iPhone、Apple TV）提供流媒体服务，则需要使用HLS。

正如arcyqwerty所说。任何HTTP服务器都可以提供HTTP流。但在服务之前，您需要准备好您的媒体文件和清单文件。

以下是一些非常重要的链接，可以阅读关于HLS（HTTP实时流媒体）：

• 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

开源服务器呢。我知道这些：

• Flumotion：http://www.flumotion.net/

• Gstreamer服务器流媒体：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）

或者你可以像我一样，使用GStreamer进行分割和制作清单。最后，我使用Nginx只是为了服务他们。

我希望我能帮你一点忙。

Answer 2

任何可以提供文件（apache、nginx、IIS等）的HTTP服务器都可以通过HTTP"流式传输"媒体。因此，如果您愿意，您可以保留RTMP的RED5，并设置一个HTTP服务器来提供相同的文件。

如果你需要一个单一的产品解决方案，那么在nginx中添加nginx rtmp模块可能是你想要的

Answer 3

我使用了它，它工作正常。（Ubuntu 12.04 TLS服务器）

逐步：

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

NGINX配置：（/usr/local/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;

events {
    worker_connections  1024;
}
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;
    #tcp_nopush     on;
    #keepalive_timeout  0;
    keepalive_timeout  65;
    gzip  on;
    server {

        #charset koi8-r;
        #access_log  logs/host.access.log  main;
        # 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：

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

下一步。。。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目录中。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：您使用VLC媒体播放器）

或html代码
