FFmpeg CLI Flags

A comprehensive list of all ffmpeg 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This type of list was originally published here, but that source is out-of-date and no longer available.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 for the full list in all its markdown-y goodness.

Usage

Hyper fast Audio and Video encoder

usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...

Getting help:
    -h      -- print basic options
    -h long -- print more options
    -h full -- print all options (including all format and codec specific options, very long)
    -h type=name -- print all options for the named decoder/encoder/demuxer/muxer/filter
    See man ffmpeg for detailed description of the options.
