I have a quiz video overlay that shows up nicely when the videojs player is in standard mode: https://jsfiddle.net/c4nxdf38/
However, when entering fullscreen it disappears (probably behind the video).
I found an obsolete solution which specifies the z-index of the overlay to the maximum. It is not working in the latest Chrome and Firefox.
I found another solution to do the fullscreen with the parent, not the videoplayer itself, but it's not working with the videojs player setup.
Then I found a promising solution how to make overlay elements appear on fullscreen by setting position:absolute; and tried to implement it without success: https://jsfiddle.net/5Lqfyzh4/
HTML from my last attempt (see fiddle):
<div id="main-container">
<div id="overlays-wrap">
<div class="overlay-item" data-overlayid="59" data-time="41">
<p class="vo-question">
Welche Zahl ist die Summe bei 3 + 50 = 53?
</p>
<div class="vtask-choices-wrap">
<div class="vtask-choice-item">
<input class="vtask-choice" type="radio" name="quiz" id="59-a1" value="1" data-correct="0">
<label class="radio-tile" for="59-a1">

</div>
<div class="vtask-choice-item">

Javascript:
$(document).ready(function() {

};
video = videojs('videoplay', options);
video.ready(function() {
/*
this.on('fullscreenchange',function() {
console.log('fullscreen event');
});
*/
}); // end video.ready
// OVERLAY PREPARE
// $('#overlays-wrap, .overlay-item').hide();
// OVERLAY INTERACTION
$('.radio-tile').click( function() {
// only show if not yet submitted, prevents submit then click again on radio-tile which would show the vtask-btn-continue
var submitted = $(this).closest('.overlay-item').hasClass('overlay-submitted');
if(!submitted)
{
$(this).parent().parent().next('.vtask-btn-continue').css('visibility', 'visible');
// make sure we check the radio button
$(this).prev('.vtask-choice').prop('checked', true);
}
});
$('.vtask-btn-continue').click( function() {
// hide continue button
$(this).css('visibility', 'hidden');
var overlay = $(this).closest('.overlay-item'); // $(this).parent()
overlay.hide();
});
}); // END ready

Interestingly, with the videojs plugin at https://github.com/brightcove/videojs-overlay the fullscreen overlays seem to work even on fullscreen. But I cannot figure out how it is doing it. – Demo: http://www.xfaktor.com/overlay/overlay_kroger.html – I have more complex HTML for my overlays and cannot use this plugin.
What is the solution for this video/videojs problem?
Probably it would be best if you can help, having the starting point of this fiddle (my recent implementation): https://jsfiddle.net/w5f7mk19/ Thanks!
The problem appears to be, that this library wraps the video in an additional div, and makes that div fullscreen - but your #overlays-wrap element is outside of that element, and I don’t think z-index is supposed to change anything about that(?).
Putting the overlay directly into #videowrapper in the source code doesn’t do the trick - the player library takes #videoplay, creates the wrapper div and puts the id on that. (It changes the id of the video element itself to #videoplay_html5_api, so no conflict in that regard.) The new div #videoplay becomes fullscreen, but #overlays-wrap still only is a sibling in the DOM, so outside of the fullscreen element.
But if you move #overlays-wrap into #videoplay after the player has initialized, it seems to work:
video = videojs('videoplay', options); // wraps video element into div#videoplay
$('#overlays-wrap').appendTo($('#videoplay')); // append #overlays-wrap to div#videoplay
