触摸屏视频播放手势支持，上下滑调整音量，左右滑调整进度
初步探索得出via不兼容部分油猴脚本的原因是via并没有内置部分油猴插件的api，导致无法使用，在via使用这个脚本的方法是： 像你那张图一样把代码全部复制进去，然后在代码最后面加上这些代码
function GM_addStyle(css){
head = document.head || document.getElementsByTagName('head')[0],
style = document.createElement('style');
head.appendChild(style);
style.type = 'text/css';
style.appendChild(document.createTextNode(css));
}
因为手机上面调试非常麻烦，而且脚本和via的手势和功能有重复，会引起竞争，所以不做适配，如果想要使用这个插件，推荐使用kiwi浏览器，本人也会在上面做测试和使用。 下面是加入后完整的代码

KIWI换这浏览器吧 我也刚从VIA换过来
从另一个脚本评论区找过来的，那个脚本功能太多，用不过来，也不知道怎么用。
想问下大佬，我用的via浏览器，不知道为啥复制代码进去不生效啊。反倒是直接用adguard加载脚本是可用的。
via里把油🐒脚本开头的那一堆声明都给删了（其它脚本也一样）
