Several HLS-player solutions are available in the market, each with its strengths and weaknesses:
HLS works by breaking a video into a series of small, short chunks. The server provides an index file (the manifest, with an .m3u8 extension) that lists playlists of renditions at varying bitrates and resolutions — such as 360p, 720p, 1080p, and so on. Each child playlist link lists the chunks of that specific rendition. The player's job is to read this manifest and dynamically switch between quality levels in real time, downloading video chunks to ensure smooth playback without buffering. hls-player
This is a more engineering-focused paper about the backend "plumbing" that feeds the HLS player.
If you are building a website or app, you do not need to build an HLS player from scratch. Excellent open-source and commercial options exist across different platforms. 1. Web Browsers (HTML5) For on the web, look into Shaka Player

Unlike traditional streaming methods that require dedicated media servers, HLS works over standard HTTP, making it firewall-friendly and highly scalable. An HLS player fetches small video segments ( .ts files) based on a playlist file ( .m3u8 ). It dynamically handles adaptive bitrate streaming (ABR), switching quality seamlessly to match the user's internet speed. How Does an HLS Player Work? Each child playlist link lists the chunks of
A good player allows users to toggle between multiple languages or closed captions seamlessly.
The player monitors the download speed of the segments. If the network slows down, the player requests lower-quality segments; if the network speeds up, it requests higher-quality segments to maximize visual quality.
