How to Play HLS Files

HLS (HTTP Live Streaming) is a widely used streaming protocol developed by Apple. It is designed to deliver audio and video content over the internet efficiently, especially for adaptive bitrate streaming. HLS files typically use the .m3u8 playlist format, which contains links to media segments in .ts (MPEG-2 Transport Stream) format. If you have an HLS file and want to play it, here’s a comprehensive guide to help you.

Before playing an HLS file, it’s important to understand its structure:

• .ts Files: These are the actual media segments that store the audio and video data.

HLS files are commonly used for live streaming and on-demand video services because they adapt to the viewer’s internet speed, ensuring smooth playback.
