直播推流nginx-rtmp-module集成

官方源码:https://github.com/arut/nginx-rtmp-module

战斗民族俄罗斯人民开发的一款NGINX的流媒体插件，除了直播发布音视频流之外具备流媒体服务器的常见功能
比如推拉流媒体资源
基于HTTP的FLV/MP4 VOD点播
HLS (HTTP Live Streaming) M3U8的支持
基于http的操作（发布、播放、录制）
可以很好的协同现有的流媒体服务器以及播放器一起工作
在线调用ffmpeg对流媒体进行转码
H264/AAC音视频编码格式的支持
linux/BSD/MAC系统的支持

编译方法:

在上一篇中,已经成功部署了nginx服务器,但是没有集成推流的功能.

1\下载该模块
2\进入nginx-1.10.1目录,重新配置configure
3\增加参数–add-module=/path/to/nginx-rtmp-module

sudo ./configure --prefix=/usr/local/nginx --with-pcre=/home/wangxiong/Soft/nginx_station/pcre-8.37 --with-zlib=/home/wangxiong/Soft/nginx_station/zlib-1.2.8 --with-openssl=/home/wangxiong/Soft/nginx_station/openssl-1.0.1t  --with-http_ssl_module --add-module=/home/wangxiong/Soft/nginx_station/nginx-rtmp-module

4\sudo make
5\sudo make install

安装完成后nginx目录:

服务器配置nginx.conf所在路径

可以用gedit或者vim打开>

#error_log  logs/error.log  notice;

        }

        #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 {

        }

    }


    # another virtual host using mix of IP-, name-, and port-based configuration

    #    server_name  somename  alias  another.alias;

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


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;

    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

默认是支持http协议,然后增加对rtmp协议,在http{}外面增加,详细配置可看官方wiki: https://github.com/arut/nginx-rtmp-module/wiki/Directives

rtmp {  
     server {  
            listen 1935;  

            application myapp {  
                live on;  
            }  
            application hls {  
                live on;  
                hls on;  
                hls_path /tmp/hls;  
            }  
      }  
}  

配置好后重启nginx;
在本地可以用ffmpeg命令进行推流,然后用ffplayer进行播放

如果用ffmpeg命令出现.so共享库找不到的问题,解决方法配置全局共享
vim /etc/ld.so.conf
在后面添加一行/usr/local/ffmpeg/lib
按Esc->wq保存退出
sudo ldconfig,生效

./ffmpeg -re -i /home/wangxiong/Documents/VID_20160508_164615.mp4 -vcodec libx264 -vprofile baseline -acodec aac -ar 44100 -strict -2 -ac 1 -f flv -s 1280x720 -q 10 rtmp://localhost:1935/myapp/testav

./ffmpeg -re -i /home/wangxiong/Documents/VID_20160508_164615.mp4 -c copy -f flv rtmp://localhost:1935/myapp/testav

推流结果

为了方便,直接用雷博士的android推流客户端,github上克隆或下载simplest_ffmpeg_android_streamer!

接下来,查看本地nginx服务器的ip地址,这个就是安卓客户端要填写的流服务器地址.

我的ip地址是192.168.1.116
1\用Eclipse导入项目工程,配置好NDK自动编译.
2\打开MainActivity,填写输入文件路径,和流服务器地址,当然我只是做了判断,如果EditText不填写,我就给一个默认的值.

               String folderurl = Environment.getExternalStorageDirectory()
                        .getPath();

                String urltext_input = urlEdittext_input.getText().toString();

                if (TextUtils.isEmpty(urltext_input)) {
                    urltext_input = "sintel.mp4";
                }
                String inputurl = folderurl + "/" + urltext_input;

                String outputurl = urlEdittext_output.getText().toString();

                String info = "";
                if (TextUtils.isEmpty(outputurl)) {
                    outputurl = "rtmp://192.168.1.116:1935/myapp/livestream";
                    // 192.168.1.116
                }
                stream(inputurl, outputurl); //native方法
                Log.e("inputurl", inputurl);
                Log.e("outputurl", outputurl);

运行build程序,点击 Start 按钮,开始将SD卡下的视频推到服务器.

注意,因为直播,我这里是在安卓上点击推流,然后在ubuntu打开浏览器访问rtmp流.
ps:安装VLC播放器:sudo apt-get install vlc 一条命令搞定.

然后选择播放应用程序,我已经安装了VLC播放器,就用它了.

直播开始啦,只要手机一直有视频推上来,播放器可以一直播放!!!
