Item-stack error
Hello everybody,
i have created an experiment with opensesame which contains videos. The problem is that i cannot run the experiment on my pc, except i delete the videos. When i do that, the experiment runs. On all other pcs, i download opensesame and run the experiment on an usb-stick with the videos without any problems. I downloaded opensesame once again on my pc but i still doesnt work, although my pc is new and all the videos run with for example vlc-player. I always adjust "legacy" . So it has to concern the videos in my experiment but i dont understand the error message. I send you the picture of the message. I hope you have an idea.

Hi Felix,
The crucial part of the error message is at the bottom, that is, the part that we can't see in your screenshot.
The best way to post the error message is by simply copy-pasting the full text. You can use

Hi,
I get exactly the same error and I was wondering if you have already a solution, since the previous post is pretty old. I checked the preferences and the packages. I cannot understand why the experiment is working in one laptop and not in another one, the one that I have to use during the testing session.
Do you a solution?
Thanks

This looks like a bug in ffmpeg to me. @Daniel Do you recognize this?
Hi Sebastiaan, hi Daniel,
the problem is still present. Do you have maybe some suggestions? We also tried with different OpenSesame versions and different video files (avi and fls) but the problem persists on that laptop.
Cheers,

Hi all,
Sorry for joining in so late, but this problem indeed appears to originate from within the moviepy module. An update to this module might fix this, but since I haven't updated the media player plugin for a while, I hope a newer moviepy version won't break anything else. In any case, I think it is worth the try.
According to the instructions from http://osdoc.cogsci.nl/3.2/manual/environment/ you can update the moviepy module by issuing the following command in the OpenSesame debug window:
Could you give this a try and let us know how it went here?
