# FFmpeg — Reference & Command Toolkit FFmpeg is a universal media converter: it reads any number of inputs (files, pipes, network streams, capture devices), filters and transcodes them, and writes any number of outputs. This skill is a practitioner's toolkit for **constructing correct command lines fast** and knowing which option, codec, or filter to reach for. > The full official source text ships with this skill at [reference/FFmpeg-Complete-Documentation.md](reference/FFmpeg-Complete-Documentation.md) (~1.9 MB). This skill extracts the structure; grep that file or the chapter files for exhaustive option lists. ## How to Use This Skill - **No arguments** — load the core mental model + the cheatsheet of common commands. - **A task** — "trim without re-encoding", "burn subtitles", "capture screen" → I map it to a pattern in [patterns.md](patterns.md) / [cheatsheet.md](cheatsheet.md). - **A topic** — "filters", "codecs", "hls", "protocols" → I read the matching `chapters/` file before answering. - **A name** — a specific filter/encoder (e.g. `scale`, `libx264`) → grep the chapter for exact options. --- ## Core Mental Model (read this first) **1. Command anatomy — order matters.** ``` ffmpeg [global_opts] {[input_opts] -i INPUT}... {[output_opts] OUTPUT}... ``` Options apply to the **next** file specified. Put input options (e.g. `-ss`, `-f`, `-r`, `-framerate`) **before** the `-i` they modify; output options before the output URL. Global options (e.g. `-y`, `-loglevel`
