Allow preload attribute to be set on video HTML5 element

[thom4parisot]

Hello,

asciidoc(tor) doc mentions the ability to use options to provide some additional video::[] macro options but it seems the HTML preload attribute to be missing.

I am willing to generate a <video src="..." preload="metadata"></video> tag in the end. buffered can be nice to control how much a user would download on his end.

Cf. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/video#Attributes

Any thoughts?

We can certainly add this support. It seems to me like it should be an attribute (key/value pair) since it accepts multiple values.

Also, is "auto" the right default or should we use a different value?

If no value is provided for preload, indeed it should be understood as auto.

If no preload attribute is added to the video element, it is already understood as being auto.
