Java wrapper around the FFmpeg command line tool

Restreamer is a self-hosted video broadcast platform and RTMP streaming server. It functions as a live media processing gateway and a multi-destination stream relay, providing a web-based management interface to configure video codecs, hardware acceleration, and stream routing. The system enables multi-platform video streaming by duplicating a single live video source and forwarding it to various third-party broadcast services and external servers simultaneously. It also supports direct-to-website broadcasting, allowing users to host live content for private or public audiences via customizab

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

ffmpeg.wasm is a browser-based multimedia processing engine that brings the capabilities of the FFmpeg library directly to the client environment. By utilizing WebAssembly, it enables audio and video transcoding, format conversion, and stream recording to occur entirely within the browser without requiring server-side infrastructure. The library distinguishes itself by executing resource-intensive media tasks in background threads, ensuring that the main user interface remains responsive during complex operations. It manages data through an isolated, in-memory virtual file system, allowing fo

node-fluent-ffmpeg is a Node.js wrapper for FFmpeg that provides a fluent interface for executing media commands and processing files. It functions as a process manager that handles the lifecycle of external FFmpeg binaries, enabling programmatic media transcoding, video thumbnail generation, and metadata extraction via ffprobe. The library distinguishes itself through a command builder that translates JavaScript method calls into command-line arguments. It features event-driven progress monitoring to track processed frames and throughput, as well as the ability to route processed media data

Vidstab is a video stabilization library which can be plugged-in with Ffmpeg and Transcode.
