## What it is
FFmpeg is the leading open-source multimedia framework, providing libraries (libavcodec, libavformat, libavfilter, etc.) and command-line tools to decode, encode, transcode, mux, demux, stream, filter, and play virtually any audio or video format. It is written in C, highly portable, and supports hardware acceleration across many platforms.

## Use cases
- convert video files between formats like mp4 to avi
- extract audio from a video file
- compress videos for the web
- record and stream live audio and video
- probe and inspect multimedia file metadata
- build an app that decodes or encodes video
- transcode with GPU hardware acceleration
- cut and trim video clips from the command line

## When to choose
- you need to convert, transcode, or remux media files
- you need broad codec and container format support
- you are building a media application and need decoding/encoding libraries
- you need to stream or record audio/video
- you want hardware-accelerated encoding or decoding

## When to avoid
- you need a polished end-user media player with a full GUI
- you need video editing with a timeline and effects rather than processing
- you want a high-level managed-language API without dealing with C libraries

## Facets
- artifact type: library
- maturity: stable
- function: video-processing, audio-processing, streaming, cli, image-processing, sdk
- domain: media, developer-tools, cross-platform
- platform: windows, bsd, cross-platform, cli, c
- tags: transcoding, codecs, muxing, demuxing, multimedia-framework, libavcodec, hardware-acceleration, media-player, audio, video, linux, macos
