## Note: In order to use this script you have to tell to mpv to enable a socket.
## Two ways are possible to achieve this:
## 1) Use the argument --input-ipc-server when you launch it. For example:
## `mpv --input-ipc-server=~/.cache/mpvsocket Your.Video.File.mkv`
## 2) Add the line below when in the `mpv.conf` file:
## `input-ipc-server=~/.cache/mpvsocket`
