Where is MPV save state location?

  • 772

Where does mpv save or log the state when using --save-position-on-quit or Shift+q?

This is used to save the exit state in order for the video to start playing from where it was left off when exiting mpv.

mpv-media-player

    On my copy of mpv:

    andrew@ilium~$ mpv --version | head -n 1
mpv 0.35.0-255-g16f0cd546d Copyright © 2000-2023 mpv/MPlayer/mplayer2 projects

    the 'saved' exit state is written in a simple text file in $HOME/.config/mpv/watch_later. An example is:

    andrew@ilium~/.config/mpv/watch_later$ ls
3F33858724ABD9E42AB6EDA66A77E92D
andrew@ilium~/.config/mpv/watch_later$ cat 3F33858724ABD9E42AB6EDA66A77E92D 
start=15.807474
andrew@ilium~/.config/mpv/watch_later$

    I note that the man pages give some clear detail on this as follows:

    ~/.config/mpv/watch_later/

Contains  temporary  config  files  needed  for resuming playback
of files with the watch later feature. See for example the Q key 
binding, or  the  quit-watch-later input command.

Each file is a small config file which is loaded if the corresponding
media file is loaded. It contains the playback position and some
(not necessarily  all)  settings that  were changed during playback.
The filenames are hashed from the full paths of the media files. It's
in general not possible to extract the  media  filename  from this
hash. However, you can set the --write-filename-in-watch-later-config
option, file.

    The option --write-filename-in-watch-later-config mentioned there seems well worth exploring as well; on my system this command:

    mpv --save-position-on-quit --write-filename-in-watch-later-config test.avi

    gives the following result:

    andrew@ilium~/.config/mpv/watch_later$ cat 3F33858724ABD9E42AB6EDA66A77E92D 
# test.avi
start=26.067734
andrew@ilium~/.config/mpv/watch_later$

    It would be a good idea to add these options to the mpv.conf file, as I have done on my own system...
