前言:
在安卓手机上，使用video播放视频有个问题，video控件层级会永远在顶层，不利于视频互动H5开发，而IOS手机上不会有此问题。
<video src="http://xxx.mp4" x5-video-player-type="h5"/>
x5-video-player-type="h5" 只适用于微信浏览器
注意:
1.jsmpeg 需要将视频转为.ts的文件
先安装ffmpeg,然后执行以下命令,将mp4格式的文件转成 .ts(用命令行转的才能正常播放)
ffmpeg -i video.mp4 -f mpegts -codec:v mpeg1video -codec:a mp2 out.ts(文件的路径不太好找,建议全局搜索一下)
2.安卓上使用jsmpeg插件渲染canvas，ios上正常使用video并加入隐藏控制条等设置
