## What it is
A Ruby gem that wraps the ffmpeg command-line tool, providing a simple API for reading movie metadata and transcoding video/audio files. It supports custom encoding options, progress tracking, and multiple audio streams.

## Use cases
- read metadata from video files in ruby
- transcode movies to mp4 with ffmpeg from ruby
- get video duration resolution and codec info
- convert video formats programmatically
- track transcoding progress in a rails app
- extract audio stream details from media files

## When to choose
- you are building a Ruby or Rails application that needs video metadata or transcoding
- you want a simple Ruby API over ffmpeg instead of shelling out manually
- you need human-readable encoding options with progress callbacks

## When to avoid
- your project is not in Ruby
- you need fine-grained frame-level control or ffmpeg filter graphs beyond custom CLI args
- you need a library actively tracking the newest ffmpeg versions or running on JRuby

## Facets
- artifact type: library
- maturity: maintenance
- function: video-processing, audio-processing
- domain: media, developer-tools
- platform: ruby, cross-platform, cli
