The libbw64 library is a lightweight C++ header only library to read and write BW64 files. BW64 is standardised as Recommendation ITU-R BS.2088 and the successor of RF64. So it already contains necessary extensions to support files which are bigger than 4 GB. Apart from that a BW64 file is able…

libear is a C++14 library to render ADM content according to Recommendation ITU-R BS.2127. It is not a complete application, but provides components to calculate gains and apply them to audio, for embedding into applications which need to render ADM content.

MP4Box.js enables advanced MP4 parsing, segmentation, and sample extraction directly in the browser or in Node.js environments. Built for performance and flexibility, it's inspired by the MP4Box tool from the GPAC Project.

Flowblade is a non-linear video editor and multitrack video compositor. It provides a professional environment for composing multitrack timelines, trimming media clips, and managing assets through a visual effects processing engine. The project distinguishes itself with a hardware-synced playback controller that allows for manual scrubbing using external USB shuttle and jog devices. It also includes a hardware-accelerated video encoder that utilizes CPU and GPU acceleration to render project timelines into final formats. The software covers a broad range of production capabilities, including

L-SMASH's official repo

Ruby wrapper around pHash, the perceptual hash library for detecting duplicate multimedia files

High level API for FFmpeg / Libav.

This project is a professional live video production suite designed for capturing, encoding, and broadcasting high-quality media. At its core, it features a real-time media processing engine that utilizes hardware acceleration to composite multiple audio and video sources with minimal latency. The application provides a centralized studio interface for managing complex scene transitions, layering visual sources through a hierarchical scene-graph engine, and streaming content to multiple platforms simultaneously. The software is built on a cross-platform abstraction layer that ensures consiste

Node.js native bindings to FFmpeg with support for asynchronous processing via streams and promises.

Kelvinadon is a cross-platform streaming library for working with Material Exchange Format (MXF) files or streams in Node.js. Kelvinadon works with highland.js to provide a means to process MXF data in stream form with back pressure.

IT swiss army knife for professional media infrastructure and production. This is a prototype Node.js application that demonstrates:

TuttleOFX project is an image processing framework based on OpenFX plugin format. More informations on the official website :http://www.tuttleofx.org.

voctomix is a video mixing software, written in python.

FFmpeg is a cross-platform multimedia framework designed for the recording, conversion, and streaming of audio and video content. It functions as a comprehensive toolkit that provides both a command-line utility for direct media manipulation and a collection of low-level libraries for integration into custom applications. At its core, the project utilizes a packet-based stream engine and a format-agnostic abstraction layer to handle diverse media standards, containers, and network protocols. The framework distinguishes itself through a modular, graph-based filter execution model that allows f
