OS: Windows 10
PsychoPy version: 2020.2.4
Standard Standalone? yes
What are you trying to achieve?: Play combination of .wav and .mpeg files to create blocks of audio-only, visual-only, and audiovisual stimuli
What did you try to make it work?:
Hello!
I have a very simple flow set up in builder right now which just consists of alternating routines to present instructions for each block then loop though a list of stimuli and collect keyboard responses for each trial (eventually I’ll add an outer loop to randomize the order the conditions are presented in across participants). As I was building the task, I initially constructed each condition type in separate files for easier testing and they all worked fine. I then rebuilt each of those components into a new file with the combined flow seen here and loaded in shortened conditions files (5 trials each) to test the full run (without subjecting myself to hundreds of McGurk videos!).
What specifically went wrong when you tried that?:
Now, when I try to run the full version, it runs through the first two conditions (audio-only and visual-only) but crashes before moving into the audiovisual block’s instructions. Given the timing of the crash and the error message I receive (below) I am wondering if it may be something to do with the video files depleting memory space as discussed in this thread - Error with demo code moviestim2 on psychopy 1.90.3 (on windows OS) - #3 by zoubochao? However, I am able to run the full set of video stimuli (many more than 5 trials) in the file I built to test this condition alone so I’m not sure if that’s it.
Any insight on what this issue might be or how to address it within the builder would be very much appreciated!
