Solution:

HTML Code:

<!DOCTYPE html><!-- Define document type as HTML -->
<html><!-- Begin HTML document -->
<head><!-- Start of document header -->
<meta charset="utf-8"><!-- Define character encoding -->
<title>Preload the video when the page loads</title><!-- Title of the HTML page -->
</head><!-- End of document header -->
<body><!-- Start of document body -->
<video width="300" height="250" controls preload="auto"><!-- Video element with specified width, height, controls, and preload attributes -->
<source src="http://localhost/html-css-exercise/basic/solution/php-demo1.mp4" type="video/mp4"><!-- Source of the video in MP4 format -->
<source src="https://www.w3resource.com/html-css-exercise/basic/solution/php-demo1.ogg" type="video/ogg"><!-- Source of the video in OGG format -->
</video><!-- End of video element -->
</body><!-- End of document body -->
</html><!-- End of HTML document -->

Explanation:

The HTML code defines a video element using the <video> tag.
The width attribute is set to 300 pixels and the height attribute is set to 250 pixels, specifying the dimensions of the video player.
The controls attribute is included to display video controls, allowing users to interact with the video playback.
The preload attribute is set to "auto", which indicates that the video should be preloaded (buffered) when the page loads. The browser will determine the best strategy for preloading the video content.
Within the <video> tag, <source> tags are used to specify different video formats (MP4 and OGG) using the src attribute and the corresponding MIME type using the type attribute.
This code creates a video player with preloading enabled to improve the user experience by reducing buffering time when the video starts playing.
