I want to increase/decrease volume with up/down key instead of 9/0 which is default in mpv player.

Follow these steps:

  1. Make a file input.conf inside ~/.config/mpv
  2. Open the file and add these lines:

    UP add volume +2
    
    DOWN add volume -2

  • UP is working but DOWN is doing the same thing as before. I ran line 4 command again and now DOWN is working. but UP went back doing the same as before. – user557728 Jun 12 '17 at 19:27

To extend on Arun's answer, it is also possible to modify other keys to other actions, for most of the keyboard keys it's as straightforward as:

[key] [action]

Where [key] is the key you want (case sensitive) and [action] is the action you want the player to do, where this page contains the full default config file, which has all the actions you can do, I couldn't find a place with the actions listed though, so it is possible it supports more actions.

For other keys however, especially non-standard keys you might need to run mpv with the flags:

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

Which will make mpv create a window that behaves like xev (although more user friendly since it shows the name of the key you pressed on screen).

This way you can then see which keys you are pressing, this is especially useful for when you're configuring the mouse with extra buttons, as some buttons may have special names in mpv.

Here is a small table of the actions from what I saw in the config file, if anyone finds somewhere with the full action list, I'll replace this with a link to there.

I have found a link to the full list/guide, but I'll leave this here as a quick lookup, the link was in here but I had just missed it.

(..) is mandatory
[..] is optional

There are more, but I figured this made a list of the most common needed ones.

(If you are wondering why I'm responding to a year old question, it's that I couldn't find the answer myself on here, but this was the first question that popped up when I searched it, so I figured anyone looking at this question might also wonder how to change all the other keys too)
