How to put a video to open in fullscreen automatically in an HTML page?

2

Apparently for a video to be in fullscreen there needs to be interaction with the user. Most players , including the native HTML5 have ' fullscreen ' button.

I'm building an interactive offline platform and need to click on a teaser button to automatically open a player by playing a video on fullscreen > and that at the end stay on or go back to the screen that was:

Ithoughtofthesetwosolutions,whicharewithinmycurrentprogrammingcapacity:

1)CreateanotherHTMLpagewiththefollowingcodes:

<bodyclass="fadein">

  <video id=video autobuffer autoplay="true">
  <source src="media_v/video.mp4">
  <object type="video/mp4" data="media_v/video.mp4" width="1366" 
height="768">
  </object>
  </video>

<script>
document.getElementById('video').addEventListener('ended',myHandler,false);

function myHandler(e) {
    window.location.href = "menu_option.html";    
}
</script>

It turns out that in this mode it does not take the whole screen, even with the measurements having the native resolution of the screen 1366x768, it leaves a border and I can not get through the entire screen object without the user clicking the fullscreen , not even using:

<script>
  var elem = document.getElementById("video");
  if (elem.requestFullscreen) {
  elem.requestFullscreen();
} else if (elem.mozRequestFullScreen) {
  elem.mozRequestFullScreen();
} else if (elem.webkitRequestFullscreen) {
elem.webkitRequestFullscreen();
}
</script>

or

video id=video autobuffer autoplay="true" fullscreen="true"

Is there "fullscreen = 'true'"?

2) The other way I thought was that clicking the 'button' already open a video 'as content overlay' in fullscreen mode, like the Facebook player, but in this case I think I do not even know where to start, so here I am.

You can change the style of the video:

 <video id=video autobuffer autoplay="true">
  <source src="media_v/video.mp4">
  <object type="video/mp4" data="media_v/video.mp4"  min-width: 100% min-height: 100%">
  </object>
  </video>

HTML 5 provides no way to make a full screen video, but the parallel Fullscreen specification provides the requestFullScreen method that allows arbitrary elements (including elements) to be created in full screen.

It has experimental support on multiple browsers .

That is, you can use this arbitrary function but you should be aware because it is not universally accepted.

The implementation of this is done as follows:

var vid = document.getElementById("bgvid");
var pauseButton = document.querySelector("#polina button");

if (window.matchMedia('(prefers-reduced-motion)').matches) {
    vid.removeAttribute("autoplay");
    vid.pause();
    pauseButton.innerHTML = "Paused";
}

function vidFade() {
  vid.classList.add("stopfade");
}

vid.addEventListener('ended', function()
{
// only functional if "loop" is removed 
vid.pause();
// to capture IE10
vidFade();
}); 


pauseButton.addEventListener("click", function() {
  vid.classList.toggle("stopfade");
  if (vid.paused) {
    vid.play();
    pauseButton.innerHTML = "Pause";
  } else {
    vid.pause();
    pauseButton.innerHTML = "Paused";
  }
})

  margin: 0;
  background: #000;
