HTML5 encourages Interoperability standards that include a variety of components which has improved web standards to the next level and provided a platform to build amazing applications on top of it.

Since it was first released with features, including accessibility to the Internet with <video> and <audio> tags, the main aim is to provide the language understood by computers and software.

These features allow all kinds of web browsers to be accessible for videos and audio. If, for a certain reason, you do not have a new version of browsers, HTML5 players still have an alternative for that, through which it makes sure that all your videos with different sizes are watchable.

Several open-source HTML5 players are available in 2021, as open-source players have their perks, including bugs that are fixed by all-time available contributors. To find the list of the best 10, you don’t need to go anywhere, have a look at the following.

Number1: VideoJS (JavaScript):

With customized features, this open-source VideoJs player using Javascript and CSS is rated first for its popularity as more than 400,000 websites with hundreds of contributors who actively maintain this project. It has additional support for flash videos and advertisements.

Features that Fallback to older technologies:

  • consistent JavaScript API to extend and manage playbacks
  • eliminates bugs and browser inconsistencies
  • full-screen mode and subtitles (although it is provided by others, many companies prefer this feature with advanced updated technology)
  • HLS: for delivering the content over the Internet, this HTTP Live Streaming is the most preferred protocol with the main purpose of providing quality to your video and audio even when mobiles switch between WIFI and mobile network.
  • Adaptive bitrate streaming: best quality videos and audios delivered via MPEG DASH and Apple’s HLS.

How to get started (Developers’ guidelines):

First things first:

Load the initial scripts and styles before invoking the actual APIs

<link href=”//” rel=”stylesheet”>

<script src=”//”></script>

Example for initializing a basic VideoJS Player, using Video.js is as simple as creating a <video> element, but with additional data-setup attributes. At a minimum, this attribute must have a value of ‘{}’, but it can include any of the Video.js options – as long as it contains valid JSON!








  <source src=”//″ type=”video/mp4″></source>

  <source src=”//” type=”video/webm”></source>

  <source src=”//” type=”video/ogg”></source>

  <p class=”vjs-no-js”>

                      To view this video please enable JavaScript, and consider upgrading to a

                      web browser that

                      <a href=”” target=”_blank”>

                      supports HTML5 video
