Add ability to define UI visibility and playback settings in JS

[Josh Carpenter]

It would be useful to have properties we can set via JS for visibility of controls and playback settings. Analogous to the attributes on the <video> element. In the interest of making the player more embed friendly for devs.

In the case of controls, I'm currently simply setting style="display:none" on the video-controls element. Works, but isn't very elegant.

Ah. Yeah, I can definitely add this feature, but I'm currently out of the office at a conference, so it may be a little while.

Hi Andrea, no rush. One of our team members may have some time to work on this also :)

in PR #22 I added the ability to hide video controls a few ways:
https://github.com/hawksley/eleVR-Web-Player#ability-to-hide-video-controls

and in PR #20 I also added the ability to load a remote video URL a few ways:
https://github.com/hawksley/eleVR-Web-Player#ability-to-load-external-video-urls-via-query-string-hash-postmessage

@jcarpenter: @hawksley: if it's still desired to allow these options to be overridden from JS, we can do that. but now the options can be overridden from JS, query-string in URL, hash, and postMessage.

fwiw, related to this: I filed issue #21 about offering a JS bundle so that you could just refer to a eleVR-player.min.js and you get a module/global you can reference like so:

var eleVRPlayer = require('eleVR-player')({
  controls: false
});

or

eleVRPlayer.init({
  controls: false
});

or something like that.

let me know if we want to keep this open or if we can close it. thanks!
