[<video> tag preload attribute handling]

That's a preload tag

Modern browsers start downoading a video file before user presses 'play', as an optimization (like buffering)

Videos with preload="none" attribute should not be downloaded (and of course not played, also)

Maxthon (4.9 and 5.0) downloads immediatly all three videos in the page, before user clicks play in any of them, even if they are marked with preload="none"

You can check that from Developer tools, Network tab

Where to check the preload attribute? Sorry I didn't find it even from F12...

 

Right-click on a video, choose 'inspect element'

In developer tools, you will be pointed at a <div> tag

Just before it, there's the <video> tag:

<video id="embed-583699a9897ea812053908_html5_api" class="vjs-tech" poster="https://67.media.tumblr.com/tumblr_ognnqnC9jE1ulku67_smart1.jpg" preload="none" muted="" data-crt-video="">

Hi there,

Thank you for your feedback and suggestion. Could you give an example for that? for which url the video's attribute is "none".

It will help us understand your point and forward that to the product team more effectively.

Regards!

example page

there are 4 <video> tags pointing to mp4 files

they have the attribute preload="none", but the video get downloaded immediatly, without pressing 'play' (see F12 -> Network tab)

Please provide a different site for this problem.
