**1 . 安装nginx**  
参考：https://blog.csdn.net/TH\_NUM/article/details/103199376

**2. 下载安装 ffmpeg**  
去ffpmpeg 下载官网的源代码：  
http://ffmpeg.org/  
安装ffmpeg

./configure
    make
    make install

RTMP 通过FFmpeg+nginx发布成rtmp和http-flv

编译nginx需要加入([nginx-http-flv-module][])模块（参考：https://blog.csdn.net/TH\_NUM/article/details/103199376），执行configure的时候要加入–add-module=path/lib/nginx-http-flv-module选项。  
nginx的具体编译过程不详介绍。

./configure --sbin-path=/usr/local/nginx/nginx \
    --conf-path=/usr/local/nginx/nginx.conf \
    --pid-path=/usr/local/nginx/nginx.pid \
    --with-http_ssl_module \
    --with-pcre=/home/dlr/wuyongyu/nginx/pcre-8.43 \
    --add-module=/home/dlr/wuyongyu/nginx/nginx-http-flv-module \
    --with-openssl=/home/dlr/wuyongyu/nginx/openssl-1.0.1t

重新编译nginx是为了集成nginx-http-flv-module这个模块，在发布rtmp的时候可以转化成支持HTTP方式的FLV。

配置nginx.conf

                dash_path /tmp/dash;
            }
        }
    
    }

配置好nginx.conf，在cmd下启动nginx服务

**第二步：编写网页端显示的代码**  
使用[video-js][]

1.进入到 nginx/html 文件夹，可以看到有两个.html文件，index.html就是Welcome to nginx!这个页面  
先把它备份一份，再自己写个index.html，用来显示视频流。内容如下:

需要从：[https://download.csdn.net/download/TH\_NUM/11990337][https_download.csdn.net_download_TH_NUM_11990337] 下载  
video-js.swf文件从压缩包中解压出来放到html 文件夹下。

PS: video-js.css和video.js文件也在这个压缩包中，也可以把它们都解压出来放到html 文件夹下

index.html

<!DOCTYPE html>
    <html>
        <head>
          <title>RTMP Sample Player Videojs</title>
          
          <link href="video-js.css" rel="stylesheet" type="text/css">
          
          <script src="video.js"></script>
          <script>
            videojs.options.flash.swf = "video-js.swf";
          </script>
        </head>
        <body>
            <div align = "center">
                <h1>RTMP Player Videojs</h1>
                <video id="example_video_1" class="video-js vjs-default-skin" controls preload="none" width="640" height="480" data-setup="{}">
                    <source src="rtmp://192.168.1.106:1935/live/mystream" type="rtmp/flv"/>
    
                    <p class="vjs-no-js">To view this video please enable JavaScript, and consider upgrading to a web browser that <a href="http://videojs.com/html5-video-support/" target="_blank">supports HTML5 video</a></p>
                </video>
            </div>
    
    
        </body>
    </html>

**ffmpeg 推流：**

ffmpeg -re -i ~/wuyongyu/video/demo.mp4  -vcodec copy -acodec copy -f flv rtmp://localhost:1935/live/mystream
    
    或则推流摄像头：
    ffmpeg -f v4l2 -video_size 640x480 -framerate 30 -i /dev/video0 -vcodec libx264 -preset veryfast -f flv rtmp://localhost:1935/live/mystream

其他：  
ffmpeg 拍照：

ffmpeg -f video4linux2 -i /dev/video0 -vframes 1 /usr/local/nginx/html/test2.jpeg -y

在浏览器地址栏输入localhost:80 或者http://localhost:80/live?port=1935&app=live&stream=mystream
