Is there a benefit to using "will-change" on the HTML5 video element?

Question

Is there any benefit on using the will-change property on an html video tag to increase performance ?

if so, how should i use it in order to make the video run on the GPU using Hardware Acceleration ?

Answer 1

will-change is used to hint the browser, that a property or the content of the corresponding DOM-Element will likely change in the near future. Therefore it requires as value a CSS-property (e.g. will-change: opacity) or the contentskeyword (will-change: contents).

If None of this is changed, I see no reason for using it on the video-tag.
