# FFmpeg CLI Flags

> A comprehensive list of all [ffmpeg](http://ffmpeg.org) commandline flags.

It's really useful for `CTRL+F` searching random flags that you may come across in the wild!

This type of list was originally published [here](https://web.archive.org/web/20170823004401/http://ubwg.net/b/full-list-of-ffmpeg-flags-and-options), but that source is out-of-date and no longer available.

The full list of flags for your local version of ffmpeg can be generated via `ffmpeg -h full`. 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.

**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.
