@LiesbethGijbels can you see if the advanced_video.py example works for you? In theory it should allow you to use expyfun video functions to show your video rather than cv2.

[larsoner]

@drammock can you look and try this out?

[drammock]

Not easily. see spatialaudio/python-rtmixer#22

[drammock]

running advanced_video.py example on Linux looks good after installing pillow(which is an unstated dependency, maybe only for screenshots?). I see the video shrinking and then moving rightward, with the background color changing behind it. Keyboard button presses do not work to pause the video however.

[drammock]

After setting config value RESPONSE_DEVICE to keyboard, I still can't pause the video.

[larsoner]

I broke that bit of the example, it should be fixed now (pausing using 1. pauses things on my machine). If you get no keyboard response at all, perhaps try simple_experiment.py to see if other experiments work or not. It will tell us if the problem is specific to this example, or to expyfun/pyglet overall

[drammock]

hmm, button presses not working in simple_experiment either. I've probably forgotten some dumb aspect of the setup; it's been so long since I set up a new system like this.

[larsoner]

Make sure the window that pops up actually has focus, you might need to click on it to get it to really have focus

[drammock]

you might need to click on it to get it to really have focus

yeah, I've been doing that; still no dice.

[larsoner]

Maybe try changing Pyglet versions? pip install pyglet==1.3.2 or pyglet<1.5 to get some 1.4 variant...?

If that doesn't work, which window manager are you running? I can try to replicate. Running just from a terminal with python -i whatever.py I assume?

[drammock]

downgrading to pyglet 1.4 worked!
