What is HLS Streaming?

HLS (HTTP Live Streaming) is a video streaming protocol developed by Apple. Instead of delivering video as a single file, HLS breaks it into small segments listed in a manifest file (.m3u8). Your browser downloads these segments one by one and plays them seamlessly. This allows adaptive bitrate streaming — the player can switch between quality levels based on your network speed. BoltStream works by parsing the m3u8 manifest, downloading every segment, and combining them into a single playable file. The entire process runs locally in your browser with no external servers involved.
