Html <video> first-frame poster on iPad - html5-video

Question

I'm trying to have a video that loads the first frame of the video as the poster but doesn't autoplay. I need it to work on desktop, iPad, and iPhone.
Desktop: You don't need anything special, this will load the first frame as a poster
<video>

</video>
iPhone: This takes a bit of a hack since on iPhone the poster isn't automatically loaded. By adding "autoplay" the browser loads the first frame as the poster, but without adding "muted playsinline" it won't actually autoplay
<video autoplay>

</video>
iPad: The iPad acts like the iPhone by not pulling the poster by default, but if you add in "autoplay" like I do on iPhone it actually autoplays which I don't want.
So how would I go about pulling in the first frame of the video as the poster without it trying to autoplay the video on load?
I've also tried preload="metadata" and it did not work.

Answer 1

I solved this problem by adding autoplay to my video tag and pausing the video on load this way:
window.onload = function(){
var myVideo = document.getElementById('myVideo');
myVideo.pause();
}
<video id="myVideo" autoplay controls>

Answer 2

Looks like adding the time for 0.1 seconds does the trick too.

A similar approach to Hemmingsen answer but instead of using the onload event on the window object you can use onLoadedData on the video element itself instead:
function handleLoadedData(event) {
event.target.pause();
}
<video autoplay onLoadedData="handleLoadedData(event)">

PS: The key here is to use autoplay on the video so Safari will load the poster image but immediately stop the video after load so it won't autoplay it.
