To play local media (video/audio) files using HTML and JavaScript, you can follow these steps:

1. HTML Structure:

Create an HTML document with the following structure:

HTML

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Local Media Player</title>
</head>
<body>
  <video id="myVideo" width="640" height="360" controls>
    <source src="path/to/your/video.mp4" type="video/mp4">
    Your browser does not support the video tag.
  </video>

  <audio id="myAudio" controls>
    <source src="path/to/your/audio.mp3" type="audio/mpeg">
    Your browser does not support the audio tag.
  </audio>

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

Replace "path/to/your/video.mp4" and "path/to/your/audio.mp3" with the actual paths to your local media files.
The controls attribute adds default playback controls to the media elements.

2. JavaScript for Additional Control (Optional):

In the script.js file, you can add JavaScript code to gain more control over the media playback:

JavaScript

const videoElement = document.getElementById('myVideo');
const audioElement = document.getElementById('myAudio');

// Play the video when the page loads
videoElement.play();

// Pause the video when a button is clicked
const pauseButton = document.getElementById('pauseButton');
pauseButton.addEventListener('click', () => {
  videoElement.pause();
});

// Mute the audio when a button is clicked
const muteButton = document.getElementById('muteButton');
muteButton.addEventListener('click', () => {
  audioElement.muted = !audioElement.muted;
});

// Seek to a specific time in the video
const seekSlider = document.getElementById('seekSlider');
seekSlider.addEventListener('input', () => {
  const currentTime = seekSlider.value * videoElement.duration;
  videoElement.currentTime = currentTime;
});

This code demonstrates basic functionality like playing, pausing, muting, and seeking. You can expand it to add more features as needed.

Key Points:

Ensure the media files are in the correct format and accessible by the web browser.
Use relative or absolute paths to reference the media files in the src attributes.
JavaScript can provide more granular control over playback and user interactions.
