N_m3u8DL-RE is a cross-platform command-line downloader for DASH, HLS, and Microsoft Smooth Streaming (MSS) media. It accepts stream URLs or files, selects video, audio, and subtitle tracks using regular-expression filters, downloads segments concurrently, and can merge or mux the resulting streams with FFmpeg or mkvmerge. It supports video-on-demand and live recording, subtitle output in SRT or VTT, partial segment ranges, request headers and proxies, stream decryption through tools such as mp4decrypt, Shaka Packager, or FFmpeg, and configurable output naming and metadata.
