This repo just exists to format it nicely and make it easily searchable by folks on the interwebs. I've also tried to break the options up into more manageable sections.\n\n**Note: Apparently, GitHub has a limit to the length of Markdown files it displays on repo landing pages.** View the readme directly [here](https://github.com/transitive-bullshit/ffmpeg-cli-flags/blob/master/readme.md) for the full list in all its markdown-y goodness.\n\n## Table of Contents\n\n- [Usage](#usage)\n-
