VLC网页播放器(支持多路)：基于跨浏览器的原生小程序系统-PluginOK中间件( https://github.com/wangzuohuai/WebRunLocal )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3.0及以上版本)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2.2.8版，XP以上系统建议使用最新版本，VLC播放程序版权归相关公司所有。

本程序具有如下优点：
1、全市场可实现较低延迟(300毫秒)的首选播放方案，主流版本浏览器都支持；2、支持多路同时播放、支持下一帧、支持回放和抓图、高清视频或大屏播放性能好；3、底层播放采用VLC这个开放源代码方案，后续服务有保障，播放格式兼容好，支持H.264和H.265；4、VLC网页播放器额外付费后可获得源代码进行定制开发；5、支持海康、大华等主流的摄像头，只要能提供标准的RTSP流，都可以播放。

1、PluginOK中间件的安装：
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PluginOK中间件服务，在安装目录下的Data子目录有ZbaService.txt日志文件输出运行情况。

2、VLC网页播放器控制相关接口：
说明：以下功能请通过Web Socket连接PluginOK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“PluginOK开发者手册.pdf”)，请在连接地址中指定端口号进行连接。
前端集成采用普通JS脚本时，请主要参考：https://gitcode.net/zorrosoft/pluginok/-/tree/master/Demo/VlcJS，需要嵌入用到的JS脚本程序是完全开源的，如果是VUE2的框架，请参考https://gitcode.net/zorrosoft/pluginok/-/tree/master/Demo/VlcVue2，VUE3框架的请参考https://gitcode.net/zorrosoft/pluginok/-/tree/master/Demo/VlcVue3。如果只是简单测试启动，可以参考
HTTP网页在线充满网页区测试：http://zorrosoft.com/vlcfull.html  HTTPS网页在线局部加载测试：https://zorrosoft.com/vlcframe.html
如还需兼容IE浏览器使用， 单机版测试网页中 <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网页播放器：
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) 20代表Electron 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
Url：加载小程序所在的网页实际地址，在网页中指定小程序的显示位置和大小，分屏多窗口播放地址和选项等，不建议使用了，建议改用Web参数
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 64启用Web参数 128防截屏 256强制显示到副屏 512允许同一网页加载多实例
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
Version播放小程序版本，0在播放小程序中播放，1在独立进程中播放
ShowType 播放窗口分屏类型，默认1只显示一个播放窗口，支持1到31的数值，多达31种分屏，注意此值不代表分屏个数
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
Option：播放参数，多个参数中间用空格区分
:rtsp-tcp 指定TCP连接播放
:network-caching=300 指定网络缓存时间，毫秒为单位，如果是播放文件时，设置:file-caching=300
LogFlag=1 指定VLC错误日志输出，默认1，设置3时同时输出警告日志

AudioOut=any 指定音频输出类型 可选mmdevice、directsound、waveout、amem、afile、NDI、adummy、none
Avcodec=any 指定硬件加速类型，none不用硬件加速，可指定dxva2、d3d11va、any，any时让播放引擎自己选合适的
Transform=none 指定VLC播放画面是否旋转，除默认none不旋转之外，设置支持90、180、270、hflip、vflip、transpose、antitranspose
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，如Open中的密码包含+等一些特殊字符，需要改到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
