I am new to psychopy and am building a short and simple experiment using video stimuli.
Unfortunately they do not work. You find deails and more information including the error message below.
I am very thankful for advice, I am sure, it is just a minor error, but I am stuck for hours and did not find the answer in the disscussion forum.
Best regards, Ines
OS (e.g. Win10): Win 10 pro
PsychoPy version (e.g. 1.84.x): v2021.2.3
Standard Standalone? (y/n) y If not then what?:
**What are you trying to achieve?:**Built a simple paradigm presenting movie stimuli (.mpeg)
**What did you try to make it work?:**vary the size, the path, the moviestim format (.mp4
What specifically went wrong when you tried that?:
The experiment starts, shows a grey screen and then stopps. When I included .png stimuli it worked finde.
Include pasted full error message if possible. “That didn’t work” is not enough information.
