Threejs + Videojs/原生video/第三方播放器 实现全景视频/全景直播播放DEMO
图片如果侵权请告知，立刻删除！
原理
- 原理其实很简单，做过全景图的同学都知道，球模型+全景图片贴图。 全景视频/全景直播就是 球模型+全景视频素材 。
- 至于播放器样式，可以自己用Js+Dom自定义，或者更改videojs（别的播放器插件也行）的样式 即便你是用原生video也是可行的 threejs官方demo就是原生video标签。
- 本demo就是拿着threejs的demo改的
- demo中videojs生成的全屏按钮点击的时候只会全屏videojs的dom 全景视频/直播是渲染在canvas上的，如果有全屏的需求，要改写这里的逻辑，让它全屏body（或者让video和canvas在一个盒子中，全屏这个盒子） 隐藏不需要的部分，或者全屏canvas，但是全屏canvas就要你把控制条部分重写了，不然全屏的没控制条
- 移动端的时候将
mousedown、mousemove、mouseup改成对应的touch事件就好了，video设置成x5-playsinline="“playsinline=”“webkit-playsinline=”" 避免全屏播放 导致canvas无法渲染video - 如果使用videojs，canvas的绘制要在视频加载完之后，监听videojs的 可播放事件 （不了解videojs的api 没测试好 不太确定）或者使用原生video标签
- 测试QQ 微信内置浏览器可行，UC内置不可使用该方法渲染 UC的video看着像新开一层webview播放的 导致自己页面上的video实际并没有播放 看着像 不确定
