'AbortError: The operation was aborted.' - Error when adjusting HTML 5 video.currentTime in Firefox

When using Firefox and changing the position of a video using HTML5 video. Does anyone have insight to what causes this?

Here are my ideas:

  1. Setting it to a time value that has no corresponding frame - I have attempted to always set it to a time where a frame exists to counter this
  2. The video frame does not load by the time the next frame is asked for - in order to test this I have set the timeout to 5 ms, this definitely drops the amount of errors so that is some evidence that this is the source of the error.

I have made slider that adjusts video time that replicates the error:

var vid = $('#v0')[0];
var slider = document.getElementById('vidSlider')
linkVideoToSlider();

vid.onplay = vid.onclick = function() {
  vid.onplay = vid.onclick = null;

  setTimeout(function() {
    vid.pause();
    slider.value = vid.currentTime / vid.duration * 100
    vid.currentTime += (1 / 29.97);

  }, 12000);

  setInterval(function() {
    $('#time').html((vid.currentTime * 29.97).toPrecision(5));
    slider.value = vid.currentTime / vid.duration * slider.max;
  }, 100);
};

function linkVideoToSlider() {
  var adjustVideoTime = function() {
    //Note that we attempt to adjust to a time that has a frame.
    setTimeout(function() {
      vid.currentTime = Number.parseFloat(slider.value / 29.97).toFixed(4);
    }, 5);
  }
  slider.oninput = adjustVideoTime
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
Frame number:
<p id="time"></p>
<video id="v0" controls tabindex="0" autobuffer preload>
    <source type="video/webm; codecs=&quot;vp8, vorbis&quot;" src="http://www.html5rocks.com/tutorials/video/basics/Chrome_ImF.webm"></source>

    <source type="video/mp4; codecs=&quot;avc1.42E01E, mp4a.40.2&quot;" src="http://www.html5rocks.com/tutorials/video/basics/Chrome_ImF.mp4"></source>
    <p>Sorry, your browser does not support the &lt;video&gt; element.</p>
</video>
<div class="slidecontainer">
  <p>Time of video slider:</p>
  <input type="range" min="0" max="1024" value="0" class="slider" id="vidSlider">
</div>

This is a reported bug in Firefox, fixed in version 70+.

AbortError: The operation was aborted

Is output to console when either:

  1. A seek in video element is aborted.
  2. The time of a video element is adjusted.

Some developers there say that Firefox performs much slower than Chrome or Edge in these scenarios, but I haven't found a way to validate a difference personally.

I will update this answer if a bug fix or workaround is found.

Update:

After updating Firefox to 70 it appears to be fixed and performance seems to have improved.
