Node Fluent Ffmpeg
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 directly to writable streams for real-time handling.
The project covers broad media processing capabilities, including encoding configuration for audio and video properties, complex filtergraph definitions for visual and audio effects, and input management for concatenating multiple sources. It also includes tools for probing media containers and streams to retrieve technical metadata.
