input.conf: help running one command strictly after another

[david-perez]

I've written a script that takes as input a file, prompts the user for a location using dmenu, and moves the file to the selected location. I'd like mpv to run it on the currently playing video and then start playing the next video in the playlist.

However, I can't figure out how to make mpv run a command, and only after it exits, run playlist-next.

I execute mpv as:

mpv --idle --force-window \
    --loop-file=inf \
    $(ls -1 --sort time --reverse *.mp4)

Let's take as an example the sleep command.

input.conf:

1 run "sleep 5" ; playlist-next

This immediately plays the next video without waiting 5 seconds. Docs say:

The program is run in a detached way. mpv doesn't wait until the command is completed, but continues playback right after spawning it.

To get the old behavior, use /bin/sh and -c as the first two arguments.

But this doesn't work either:

1 run "/bin/sh" "-c" "sleep 5" ; playlist-next

Adding the sync command prefix:

1 sync run "/bin/sh" "-c" "sleep 5" ; playlist-next

doesn't work either.

I also tried using subprocess instead of run, which supposedly "does not detach the process":

1 subprocess "sleep 5" ; playlist-next

but the behavior is identical.

Get the old behavior refers to calling the shell, not to waiting until the command is completed. subprocess can't be used in input.conf, you need to call it from a Lua script.
