  Hi,

  What is your current approach? And what is the trouble you are having? I've never tried, but I have the hunch it is a bit tricky to have a video keep on playing while the experiment continues in the background until a sounds is played. The reverse (playing sound, while a video is being started) should be more doable.

  Hi! Sorry for the extremely slow reaction, I have been quite ill for a while.

  I copied code from another experiment that did something similar, but with a picture instead of video. I want to continue playing the video and have a beep every 30 seconds, but the beep is not inherent in the video (because depending on the mouse click, the beep must come at different times during the video).

  from openexp.keyboard import keyboard
  from openexp.synth import synth
  from openexp.canvas import canvas

  The name of the sketchpad to draw on

  media_player_mpy = 'new_media_player_mpy'

  Allowed keys

  allowed_keys = ['k']

  Timeout

  timeout = 18000

  Create objects

  my_keyboard = keyboard(exp, keylist=allowed_keys, timeout=18000)
  my_synth = synth(exp)
  my_canvas = canvas(exp)

  Collect a response until timeout, show the latest response

  and play a sound everytime that a response is given

  response = 'timeout'
  start_time = self.get('time_%s' % media_player_mpy)
  while self.time()-start_time < timeout:
  key, time = my_keyboard.get_key()
  if key != None:
  response = my_keyboard.to_chr(key)
  my_synth.play()

  Log the response

  exp.set('response', response)

  Hi,

  If you don't use plugins but play a video from within an inline_script, it will, most likely, be possible. I recommend you figure out how to play videos first (separately of the simultaneous sounds), and once you figured it out, you can try to integrate them. Check out this part of the documentation (particularly the opencv part): https://osdoc.cogsci.nl/3.2/manual/stimuli/video/

  Does that help?
