## What it is
N_m3u8DL-CLI is a Windows command-line downloader for m3u8/HLS/DASH streams, built on .NET Framework 4.6. It supports AES-128-CBC decryption, multithreaded downloading, resumable transfers, custom headers, live stream recording, and automatic merging of segments into mp4/ts via ffmpeg.

## Use cases
- download m3u8 video streams to mp4 or ts
- decrypt AES-128-CBC encrypted HLS streams
- record live HLS streams
- download only a specific time range of an m3u8 stream
- resume interrupted video downloads
- download subtitle and audio tracks from a master playlist

## When to choose
- you are on Windows and need a simple, scriptable m3u8/HLS downloader
- you need AES-128-CBC decryption, custom headers, or proxy support out of the box
- you want a lightweight tool with rich CLI options and a simple helper GUI

## When to avoid
- you need cross-platform support (Linux/macOS) - use N_m3u8DL-RE instead
- you need active development or new features - the project is in maintenance mode
- you need to decrypt Youku or Balloon Cloud video streams, which are explicitly unsupported

## Facets
- artifact type: cli-tool
