猿大师播放器是基于跨浏览器的原生小程序系统-猿大师中间件网络高级版开发，底层调用ActiveX控件VlcOcx.dll(需安装VLC media player或搭配绿色版VLC桌面程序)可实现在网页中内嵌播放多路RTSP实时视频流。最低可用在Chrome 41、Firefox 50、Edge 80(Chromium内核)、360极速/安全、IE、Opera、Electron、Vivaldi、Brave、QQ等浏览器，也兼容运行于这些浏览器的最新版本，建议在Windows 7及以上版本使用，XP下VLC建议用3.0.3版。
猿大师播放器具有如下优点：
1、在支持主流版本浏览器的前提下，是当前市场中可实现低延迟(300毫秒)的成熟播放方案；
2、支持多路同时播放、动态切换播放源、支持回放、字幕、水印、录像及抓图，尤其是高分辨率视频或大屏播放体验好；
3、底层播放技术采用VLC的开放源代码方案，播放器后续服务有保障，播放格式兼容好，同时支持H.264和H.265无压力；
4、VLC网页播放小程序额外付费后可获得其源代码进行定制开发，自主可控；
5、支持海康威视、大华、华为等各厂家的摄像头，支持内网，只要能提供标准的RTSP流，都可以播放；
6、前端代码接口丰富、集成简单，支持VUE等主流框架，简单JS调用即可完成集成；
7、移动端可直接采用VLC开放源代码的APP来使用，无需单独开发，投入少见效快；
8、此技术方案可实现在原有技术体系下的平滑升级，降低了方案大改造带来的技术路线和延期交付风险，可节省大量研发成本。
1、猿大师播放器的安装：
1)、如果是exe的安装程序，请直接运行安装；
2)、如果是绿色版的程序包，请解压到磁盘某个目录后，双击“InstallWrl.bat”进行安装；
3）、安装完成时会启动猿大师中间件服务，在安装目录下的Data子目录有WrlService.txt日志文件输出运行情况。
2、猿大师播放器控制相关接口：
说明：以下功能请通过Web Socket连接猿大师主服务(ws://localhost:83?sid=12345&flag=1)后可执行，如默认侦听端口不是83(关于如何配置侦听端口，请参考SDK包中的文档“猿大师开发者手册.pdf”)，请在连接地址中指定端口号进行连接。
单屏全页面显示：http://test.yuanmaster.com/vlcwebfull.html
多屏局部显示：http://test.yuanmaster.com/VLCWebPlayer.html
如果您是VUE框架的，我们还有VUE框架页面测试，可以直接测试截图、录像、水印、字幕、多屏播放等功能。
网址：http://test.yuanmaster.com/VLC/#/
如还需兼容IE浏览器使用，网络版测试网页中 <object ID="WrlWS" CLASSID="CLSID:C0971B90-4513-4E2D-A0B6-15B915FE748A" width="0" height="0"></object>
的CLSID需要替换为：21ADE2E6-B4DD-4F3E-8BD5-9DDAD1785F3A
前端集成可参考以上测试网页进行，需要嵌入用到的JS脚本，另外脚本程序是完全开源的。
播放窗口选中状态时单击或按字母F即可全屏显示，全屏显示状态通过ESC、Windows按键、ESC或字母F取消，全屏切换会发送JSON包的VLC_FullScreen通知。
1)、请求启动VLC网页播放小程序：
Type为浏览器类型，传0自动判断(前提是当前浏览器已启动并显示在最前端，Flag指定当前页加载时必须是0) 可强制指定浏览器类型Type(1代表IE 2代表Chrome 4代表Firefox 8代表Opera 16代表Edge(Chromium内核) 32代表360极速浏览器 33代表360安全浏览器 34代表360企业安全浏览器 50代表QQ浏览器 60代表搜狗浏览器)
Title：网页标题中的关键词
Flag掩码标记：1指定新标签加载(1和16都不指定时为当前页加载) 2小程序显示窗口边框 4不自动裁剪越界窗口 8自动适配网页高度和宽度显示
Url：加载小程序所在的网页实际地址
ShowType 播放窗口分屏类型，默认1只显示一个播放窗口，支持1-22 24 25等多达20种多窗口播放
IframeX和IframeY分别为iframe嵌套的横竖偏移修正坐标
BarW和BarH分别是网页右侧和底部预留区域，ScrollTop为顶部滚动预留高度
小程序实际显示首先会基于Web或Url中指定的坐标和大小，再根据IframeX、IframeY、BarW、BarH设定的值做修正
Web：播放配置(新增方式)，可代替Url使用，Flag值+64使用此配置，此命令中必须指定Left、Top、Width、Height的值
Open ：启动后第一个窗口自动播放的流地址或本地多媒体文件路径，斜杠替换成/再传，也可以在Web中指定
注意：Open、Url、Web中如果有特殊字符= & 双引号或中文等，需要用URL编码处理后传递 如非本地全路径，默认使用中间件程序Data子目录作为根目录使用
举例：
