## What it is
An Electron-based desktop application for downloading and playing HLS (M3U8) video streams, with support for multi-threaded downloads, resumable transfers, and AES-encrypted stream decryption. It converts downloaded streams losslessly to MP4 files.

## Use cases
- download m3u8 hls videos to mp4
- download encrypted aes-128 hls streams
- resume interrupted video downloads
- capture m3u8 url from browser network tab and download
- record hls live stream
- download local m3u8 playlist file with custom headers

## When to choose
- you need a GUI desktop app to download HLS/M3U8 video streams
- you need to decrypt AES-128/192/256-CBC encrypted streams with custom keys and IVs
- you want multi-threaded, resumable downloads of segmented video
- you need cross-platform support on Windows, macOS, and Linux

## When to avoid
- you need a command-line tool for scripted or automated downloads
- you need non-standard AES-CBC encryption support out of the box
- you require a project with an explicit open-source license for commercial use
- you need DASH or non-HLS streaming protocol support
