hls

HLS with video resolution switcher button
The external library that helps in appending the resolution selector button works well with video.js version 5
if you use it with higher version of video.js ,you might run into errors

[Video.js - HTML5 Video Player][vjs]

Player In Action

Video player to play HLS video and have a video quality switch button

A video player that plays m3u8 format videos and lets the user to switch video quality manually

HLS

It has many streams(quality) of one video i.e 360p,480p,720p. And it adpats to stream based on network stream
How to create m3u8 file

Problem

HLS video automatically switch video quality depending on the network speed.
It adapats to internet speed and gives you the video

● What I wanted was, to have a button to switch between the quality

Found 2 solution

many thanks! I needed to change between qualities and was able to do it with the last code snippet, here is what I did:

var qualities = [];
player.one("loadedmetadata", () => {
  qualities = player.
  tech({ IWillNotUseThisInPlugins: true }).
  hls.representations();
});

function changeQuality(qualityIndex) {
  qualities.forEach(quality => quality.enabled(false));
  qualities[videoIndex].enabled(true);
}

hope is useful for somebody!
