一个视频上传的奇怪问题
一个9:16的视频，A上传到sp.hydee.cn平台，所有用户看这个视频都发现，这个视频在预览和播放的时候被拉伸变形了。<br /><br />
A将这个视频发送到sp.hydee.cn的技术人员，技术人员上传到sp.hydee.cn的时候却都是正常的，技术人员说可能跟网速有关。<br />

根据DeepSeek的方法进行了检测，得出以下几点<br />
<br />
1、视频元素据没有问题<br />
2、网站平台没有进行编码转换<br />
3、video标签参数是object-fit: contain;/* 保持比例，不拉伸 */<br />
<br />
现在不知道问题出在哪里了，有这方面经验的大佬吗？指点一下，谢谢了。<br />
