Features:
- Supports downloading streaming videos (HLS/M3U8 videos) and automatically merges and converts video fragments into a single MP4 file.
- Supports multiple resolutions (if provided by the target video).
- Multi-threaded concurrent downloading to improve download speeds, which is particularly useful for large files.
- Supports downloading HLS live streams.

Notes:
- This add-on cannot download encrypted HLS videos.
- This add-on only supports regular web videos (e.g., HLS videos played through m3u8, mp4, webm, etc.). It does not provide special adaptation for specific websites.
- This add-on temporarily occupies your memory during operation; the larger the downloaded content, the more memory it consumes. Memory is released after the download completes.
