YouTube在脚本中动态检索其视频。它从https://i.ytimg.com/*中检索缩略图。我猜你可以尝试上传一个YouTube视频，并使用你上传的视频的图片源作为目标缩略图。但是，无论何时调整显示尺寸或重新加载更多视频到主页，缩略图都会恢复原样。
英文:
Youtube retrieves their videos dynamically in a script. It retrieves the thumbnails from https://i.ytimg.com/*. My guess is that you can try to upload a youtube video with the thumbnail of your target, and use the image src of your uploaded video. But whenever you resize the display dimension or reload more videos on to your homepage, the thumbnails will revert back.
