FFmpeg is a collection of libraries and command-line tools for processing multimedia content, including audio, video, subtitles, and related metadata. Its libraries provide codec implementations, streaming and container-format handling, filtering through directed graphs, device access, audio mixing and resampling, and image scaling and color conversion. The toolset includes ffmpeg for manipulating, converting, and streaming media, ffplay for playback, and ffprobe for inspecting media content. The codebase is mainly licensed under the LGPL, with optional components under the GPL. The repository is an official mirror of the FFmpeg project's Git repository; the project directs contributors to submit patches through its mailing list rather than GitHub pull requests.

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. The project is distributed under the MIT License.

AVAL is an open-source web format and runtime for short prerendered motion with continuous loops, named application states, authored triggers, bounded transitions, reversals, frame-accurate timing, and packed-alpha transparency. It packages a logical animation as codec-specific .avl files containing motion units and a state graph; the browser selects a decodable candidate from an AV1, VP9, H.265/HEVC, and H.264 ladder, while graph routes handle state changes rather than timestamp seeking. Projects are compiled from a motion.json file with the @pixel-point/aval-compiler package, producing a directory containing the .avl output and build metadata. AVAL requires the integrating application to handle unsupported browsers and fatal playback errors and does not itself create or reveal fallback video, image, text, or other content.

mStream is a self-hosted music streaming server that serves audio from a folder-based music collection. It supports Subsonic and DLNA, transcodes audio, and provides features including album-art lookup, lyrics support, automatic backups, an Auto DJ, jukebox control, torrent and yt-dlp integration, and optional federation and peer-to-peer music discovery. It is distributed through standalone binaries for Windows, macOS, and Linux, Docker, source installation, and open-source mobile apps.

Termixer is a terminal-based two-deck DJ mixer for Unix, built in Rust with ratatui for live performance with TidalCycles. It controls audio from MPV and SuperCollider and provides deck faders, panning, three-band EQ, low- and high-pass filters, crossfading, cue output, microphone input, and a 4x4 sample-pad grid with sequencing. It can record deck, master, microphone, synthesizer, or pad output to MP3, WAV, FLAC, or OGG, and supports SuperCollider SynthDefs, a built-in sine synthesizer, Vim-style navigation, and JSON import/export for pad and sequence sessions. Installation is available through crates.io, GitHub release archives, or source; MPV and FFmpeg are required for the corresponding playback and recording functions, while SuperCollider is optional for TidalCycles integration.
