input.conf

The input.conf file consists of a list of key bindings, for example:

s screenshot      # take a screenshot with the s key
LEFT seek 15      # map the left-arrow key to seeking forward by 15 seconds

Each line maps a key to an input command. Keys are specified with their literal value (upper case if combined with Shift), or a name for special keys. For example, a maps to the a key without shift, and A maps to a with shift.

The file is located in the mpv configuration directory (normally at ~/.config/mpv/input.conf depending on platform). The default bindings are defined here:

https://github.com/mpv-player/mpv/blob/master/etc/input.conf

A list of special keys can be obtained with

mpv --input-keylist

In general, keys can be combined with Shift, Ctrl and Alt:

ctrl+q quit

mpv can be started in input test mode, which displays key bindings and the commands they're bound to on the OSD, instead of executing the commands:

mpv --input-test --force-window --idle

(Only closing the window will make mpv exit, pressing normal keys will merely display the binding, even if mapped to quit.)
