## Description

HLS Downloader is a browser-integrated utility designed to detect, capture, and assemble fragmented streaming media content directly from web pages. It functions as a browser extension that identifies HTTP Live Streaming manifests, allowing users to download video, audio, and subtitle tracks as complete, playable local files.

The tool distinguishes itself by performing all processing tasks entirely within the browser environment. It utilizes native browser primitives to decrypt protected media segments and reconstruct fragmented binary streams into unified files. By intercepting network traffic and parsing stream metadata, it enables users to select specific resolutions, audio languages, and subtitle tracks before initiating concurrent download operations.

The software provides comprehensive management for media capture, including automated playlist detection and manual link registration. It handles the orchestration of network requests, automatic retries, and the final muxing of media assets into portable formats. The project is distributed as a browser extension, providing a centralized interface for monitoring download progress and managing exported media files.
