preload 属性是 HTML 5 规范的一部分。 Steve Souders blog post讨论了允许的值并解释了每个浏览器如何处理该属性。

• no preload attribute - Preload is not specified.
• preload='none' - From the spec, “Hints to the UA that the user is not expected to need the video, or that minimizing unnecessary traffic is desirable.”
• preload='metadata' - “Hints to the UA that the user is not expected to need the video, but that fetching its metadata (dimensions, first frame, track list, duration, and so on) is desirable.”
• preload='auto' -“Hints to the UA that optimistically downloading the entire video is considered desirable.”
• preload or preload='' - The preload attribute is specified but no value is given. Specifying the empty string is the same as specifying “auto”.

关于 mediaelement 播放器，这将取决于您使用的是默认播放器还是后备播放器。但是，为了使用默认播放器预加载一定数量的视频，您不希望将该值设置为“无”。
