I’m making a Python script to play music through VLC and I wanted to add a way to control audio playback of VLC, like pause/play, next/previous, etc.
I know I can change shuffle mode before launching VLC with the --random and --no-random arguments. However, is there a way to change playback settings through the Linux terminal while VLC is running?


VLC appears to support MPRIS, so commands like
$ playerctl play-pause $ playerctl next $ playerctl previousShould be able to control it. See the Relevant arch wiki page for more info.
VLC also appears to have a TUI interface. Check out the VLC wiki
There’s also a CLI interface accessible through
cvlcThank you so much! One more thing: would there be a way to check if the user has
playerctlinstalled on their system? Or is there a Python package like it?You can test if a command exists in several ways, but the most portable one should be using
command -vwhich is POSIX.if command -v playerctl &> /dev/null # do things else # warn and exit (or prompt for installation) endThat depends on your distro. On Debian/ubuntu(-based) distro’s, you can try
apt list --installed playerctl, which will output nothing if the package isn’t yet installed, or the package name with version info if it is installed. To install it, runsudo apt install playerctlOn arch(-based) distro’s, you can try
pacman -Qi playerctl, which should return an error if there is no such package installed, or several lines of info if it is installed. To install it, runsudo pacman -S playerctl, ideally after running a full system upgrade withsudo pacman -SyuTesting if the current shell can execute something does not require looking at the installed packages, there are portable ways to do that
You could always run
whereis playerctland parse the output with awk or sedwhereisis not a Bash built-in so it may itself not be installed, plus it exits 0 and returns output even on no match requiring additional logic/processing.whichorcommandare more robust choices for this usecaseIf you don’t want a playerctl dependency you can use a dbus library to check for mpris players manually, though it’s a little less readable

In section 2.3 it explains how to use D-Bus and I think OP should use it instead
