Pausing Spotify and playing a random video in Python – A party trick for Halloween

For a Halloween party last weekend I wrote a python script to pause Spotify, play a random video and start music playback again. The videos were basic ogg files I cobbled together which showed a scary image and evil laughs or screaming with OpenShot. I can’t really share them, as I don’t have rights to the media, but it’s pretty simple to recreate them yourself.

The code for this script is on Github, and I’ve reproduced the latest snapshot below. Feel free to fork and improve if you want to scare your guests, or add support for other OS’s. Presently it only supports Linux because I used dbus to perform the play/pause actions.


This is a Halloween party script which pauses Spotify and plays a video
at random intervals.

import random
import subprocess
from subprocess import call
from time import sleep
import os
import datetime

start_time = datetime.time(21, 0, 0)
stop_time = datetime.time(23, 0, 0)

video_dir = '/home/alex/Videos/scream/'
videos = { 'scream1_nofade.ogg': 30,
'happy.ogg': 1,
'evil_laugh.ogg': 5,

def time_in_range(start, end, x):
"""Return true if x is in the range [start, end]"""
if start <= end:
return start <= x <= end
return start <= x or x <= end

def weighted_choice(weights):
total = sum(weights[video] for video in weights)
r = random.uniform(0, total)
upto = 0
print("total: %s\nrandom: %s" % (total, r))

for video in weights:
w = weights[video]
if upto + w > r:
return video
upto += w
assert False, "shouldn't get here"

def spotifyPause():
command = "dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Pause"

def spotifyPlay():
print("playing spotify")
command = "dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlayPause"

def play_video(video_file):
print("Playing %s" % video_file)
#call(['/usr/bin/mplayer', '-fs', video_file], stdout=None, stderr=None)
#result = subprocess.Popen(['/usr/bin/mplayer', '-really-quiet', '-fs', video_file])
result = subprocess.check_call(['/usr/bin/mplayer', '-really-quiet', '-fs', video_file], stdout=None, stderr=None)
return result

def playBuzz(buzzfile):
result = subprocess.check_call(['/usr/bin/mplayer', '-really-quiet', '-ss', '18', buzzfile], stdout=None, stderr=None)
return result

def infiniteLoop():
while 1:
current_time =
#if current_time > stop_time or current_time < midday:

choice = weighted_choice(videos)

random_time = random.randrange(1200,2400)
random_time = 3

video_file = video_dir + choice
print("Chose video %s after %s seconds" % (video_file, random_time))

# Whether to play buzz
buzz = False
if random.randrange(0,100) > 90:
buzz = True

# Continue if outside time range
if not time_in_range(start_time, stop_time, current_time):
print("Not playing video, outside time range")

# Do it
if buzz:

if __name__ == "__main__":

    How can this code be tweaked to play a random mp3 from a list of 20 songs after a certain time of being idle or inactivity? This code seems to force stop Spotify after a period of time, however, I need it to be the opposite. Any advice?
