RTMP 实时推流到web页面
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

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 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

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
