Video Player Project

Now, we are going to create a custom video player using the video API.

The HTML

The HTML is pretty simple. We have our video element and then some custom controls and a time display. We are also including font awesome because we are using it for the icons.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta http-equiv="X-UA-Compatible" content="ie=edge" />
    <title>Custom Video Player</title>
    <link
      href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css"
      rel="stylesheet"
      integrity="sha384-wvfXpqpZZVQGK6TAh5PVlGOfQNHSoD2xbE+QkPxCAFlNEevoEH3Sl0sibVcOQVnN"
      crossorigin="anonymous"
    />
    <link rel="stylesheet" href="style.css" />
  </head>
  <body>
    <video
      src="media/clouds.mov"
      poster="media/poster.png"
      id="video"
      class="screen"
    ></video>
    <div class="controls">
      <button class="btn" id="play">
        <i class="fa fa-play fa-2x"></i>
      </button>
      <button class="btn" id="stop">
        <i class="fa fa-stop fa-2x"></i>
      </button>
      <input
        type="range"
        id="progress"
        class="progress"
        min="0"
        max="100"
        step="0.1"
        value="0"
      />
      <span class="timestamp" id="timestamp">00:00</span>
    </div>

    <script src="script.js"></script>
  </body>
</html>

The CSS

The CSS is quite long, mostly because we used a custom slider. You don’t really need to pay much attention to this part as this is not a CSS course.

}

@media (max-width: 800px) {
  .screen,
  .controls {
    width: 90%;
  }
}

The JavaScript

Let’s start by bringing in what we need from the DOM:

const video = document.getElementById('video');
const play = document.getElementById('play');
const stop = document.getElementById('stop');
const progress = document.getElementById('progress');
const timestamp = document.getElementById('timestamp');

Play/pause video

Let’s create a function to toggle the video between playing and pausing and add the event listeners. I want it on the play button as well as the video itself.

function playPause() {
  if (video.paused) {
    video.play();
  } else {
    video.pause();
  }
}

video.addEventListener('click', playPause);
play.addEventListener('click', playPause);

Update icon

Now let’s update the icon. If it is playing, the icon should show a play icon, if it is paused, it should show a pause icon.

function updateIcon() {
  if (video.paused) {
    play.innerHTML = '<i class="fa fa-play fa-2x"></i>';
  } else {
    play.innerHTML = '<i class="fa fa-pause fa-2x"></i>';
  }
}

video.addEventListener('pause', updateIcon);
video.addEventListener('play', updateIcon);

Stop video

Let’s create the stop function and event.

function stopVideo() {
  video.currentTime = 0;
  video.pause();
}

stop.addEventListener('click', stopVideo);

Progress bar

Let’s make the progress bar function. We can use the timeupdate event to do so.

function updateProgress() {
  progress.value = (video.currentTime / video.duration) * 100;

  // Get minutes
  let mins = Math.floor(video.currentTime / 60);
  if (mins < 10) {
    mins = '0' + String(mins);
  }

  // Get seconds
  let secs = Math.floor(video.currentTime % 60);
  if (secs < 10) {
    secs = '0' + String(secs);
  }

  timestamp.innerHTML = `${mins}:${secs}`;
}

video.addEventListener('timeupdate', updateProgress);

Set progress bar

We also want to be able to click anywhere on the bar and have it take us to that point in the video.

function setVideoProgress() {
  video.currentTime = (+progress.value * video.duration) / 100;
}

progress.addEventListener('change', setVideoProgress);

That’s it! We now have a custom video player using the video API.
