Preload / Autobuffer Media Element HTML5 on iOS

I don't think iOS can handle preload / autobuffer of html5 videos. Is this correct, or can anyone else tell me how they've managed to do it?

Clarification: I want the content of the video to begin downloading before the play button is click开发者_如何转开发ed.

Is it do do with this: how to get your HTML5 MP4 video file to play before being fully downloaded? As it usually is.

You can't. Some mobile devices like iOS devices will not preload the video in order to protect their users' bandwidth. Same restriction for the same reason to autoplay attribute
