HTTP Live Streaming (HLS) is a technology for delivering streaming audio and video over the internet. HLS is a popular and widely-supported streaming protocol, and is used by many streaming platforms and services, such as YouTube, Facebook, and Twitch. HLS works by dividing the video or audio content into small segments, and then delivering each segment to the user over HTTP, the same protocol that is used for delivering web pages and other web content. HLS uses a playlist file, which is a text file that contains the URLs of the segments, to control the playback of the video or audio content. HLS is adaptive, which means that it can automatically adjust the quality of the video or audio to match the user's device and network conditions, and can provide a smooth and seamless streaming experience.
