前言

由于html中的video现在不支持rtmp协议(需要重写播放器框架，flash被一刀切，360浏览器还在支持flash),遂用rtmp作为桥梁,实际是hls协议在html中起作用.
在此推荐一款前端播放器,.ckplayer
简直了,写点页面,一直循环，洗脑神曲 dream it possible.

搭建nginx服务器

环境准备

1.下载环境

nginx包: nginx包
RTMP模块包:nginx-http-flv-module 模块包

2.依赖项

yum -y install unzip
yum -y install gcc-c++ 
yum -y install pcre pcre-devel  
yum -y install zlib zlib-devel 
yum -y install openssl openssl-devel

3.安装

新建nginx路径

mkdir /usr/local/nginx

将下载的模块包复制到nginx目录下，并解压

cp /opt/toos/nginx-http-flv-module-1.2.6.zip  /usr/local/nginx/nginx-http-flv-module
cd /usr/local/nginx
unzip nginx-http-flv-module

安装nginx服务器

tar -zxvf nginx-1.8.1.tar.gz
cd nginx-1.8.1
./configure --prefix=/usr/local/nginx  --add-module=/usr/local/nginx/nginx-http-flv-module
make && make install

4.ffmpeg推码

下载ffmpeg模块包
ffmpeg模块包:ffmpeg

查询设备

ffmpeg -list_devices true -f dshow -i dummy

在这里插入图片描述

测试录像设备可用

ffplay -f dshow -i video="BisonCam, NB Pro"

ffmpeg -f dshow -i video="BisonCam, NB Pro" -vcodec libx264 -vf scale=320:240 -preset:v ultrafast -tune:v zerolatency -f flv rtmp://[ip地址]/[你的application,我上面的application写的[myapp]]myapp/[文件名称]wechat

跨域问题(在nginx中添加跨域)

add_header Access-Control-Allow-Origin *;
    	add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';
    	add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';

5. 在html中访问。
