Breakdown after stimulus random stop

OS (e.g. Win10): Win10
PsychoPy version (e.g. 1.84.x): 2022.2.1
What are you trying to achieve?:
I have this experiment and my question is about the ‘movies’-routine:

I show movies and want them to stop at different moments, in a random order as specified in the code:

And it actually works, the movie stops at one of these durations - but not only the movie stops, but the whole experiment, it doesn’t go to the next routine.

At the beginning and the end of the routine I did the following:

in the movie properties, I specified the Stop duration with the created variable:

My loops looks like this, each movie should be shown once:

What specifically went wrong when you tried that?:
When I run the experiment, the movie stops as I desire, but also the whole experiment stops and
I get the following error message:

If anyone has an idea why the whole experiment stops, I would be thankful to learn about it :slight_smile: Thank you very much!!

If you change $stim_dur to stim_dur[trials_3.thisN] does it run further along? I don’t think the “$” is required with the timing boxes, but if that doesn’t work try it with the “$” back in front.

Hi :slight_smile:
Thank you for your reply.
With this specification, the movies don’t start to play anymore (with and without $).
I don’t know if it matters, but the output data file the trials_3.thisN column empty

Does it playthrough if you put in a time instead of a coded time? So if you put a duration of 10 seconds for testing purposes, does it move to the next file or does it still throw an error?

Yes, if I put 10 sec it works fine.

Anyone has some further ideas how I can make my experiment run? :pray:

Could you please provide a copy of

  • the .log file from your data folder (after running with your initial set-up, not with the suggested fix above)?
  • your Builder .psyexp file, and
  • the empathymovie.xlsx conditions file.

But before doing that, please:

  • delete the sstim_dur = 0 from the “begin experiment” tab – it isn’t (or shouldn’t) be doing anything, if sstim_dur gets defined in the “begin routine” tab.
  • please also confirm the actual durations of the movie files – in particular, do they all exceed 60 s?

PS Your approach seems perfectly sensible – so it isn’t clear why it isn’t working.

Hello,

Thank you so much for your reply.
All movie files are longer than 1.41min.
When I use the newest version of psychopy, the movies doesn’t start because PsychoPy does not respond anymore. In this version I upload now, I used the version 2020.1.1.

A second point that occurs now is that the movie presentation is 50 or 60 sec, even though I put the code on showing between 0.5 and 3 sec.

Here are the 3 files:

Thank you very very much!

Thanks, that all seems OK, although the log file doesn’t give any useful information.

Going back to you original report, can you scroll up there and provide the entire error report? I’m guessing it starts earlier and will give us a clue as to where in your script (as opposed to within ffpyplater_player.py) the error arises.

Hi Michael,

thanks so much for your help.

There is no solution for this error ?

raise RuntimeError(“Cannot close stream, not opened yet.”)

12

I was opening this new thread with maybe a more precise title: Raise RuntimeError(“Cannot close stream, not opened yet.”)
Maybe it helps to find a solution
