I love mpv player for it's modern minimalist look, easy moving along a video simply with mouse scroll and robust rendering of .mp4 videos.

However I could not figure out how to change playback speed as I can do easily in vlc playback menu. I simply can not see any GUI option to do so. Nor could I find a relevant configuration trick in the wiki.

So appreciate your hints if there is a hidden button or a config tweak to define a shortcut key to do so. I'm using mpv on Ubuntu 18.04.

Are there shortcut keys to change the playback speed in mpv?

You need to refer to the manual:

The reference manual lists all the options and configuration options mpv understands, key bindings, scripting, and other customizations.

Use the following keys:

[ and ] Decrease/increase current playback speed by 10%.

{ and } Halve/double current playback speed.

Backspace Reset playback speed to normal.

    Is there a way to change those 10% to a different value (like 50%)? – icl7126 Nov 06 '21 at 18:36
  • No idea, I use VLC. – DavidPostill Nov 06 '21 at 18:39
  • @icl7126 you can by creating custom shortcuts in your `input.conf` file: ` add speed 0.25` or ` add speed -0.25` will make those keys change speed by 0.25 instead of 0.10. – Grzegorz Adam Hankiewicz Dec 09 '22 at 20:53

    @GrzegorzAdamHankiewicz Yes, [here is the whole list of supported commands](https://raw.githubusercontent.com/mpv-player/mpv/master/etc/input.conf). I've actually bought bluetooth NumPad and re-assign keys to change speed to specific values, like `KP1 set speed 2.0`. – icl7126 Dec 10 '22 at 09:01
