Dear community，my psychopy version is 2021.2.0. I was designing a experiment where participants watch a video and do a forced-choice. The video is in MPEG format. When I run it, the video stimuli was not presented.
I’m lookings for suggestions.Thank you very much!
There have been quite a lot of changes & improvements to video playback since 2021, it may be worth upgrading to the latest release and trying again. Are you running locally or online?
Dear TParsons, I use the Psychopy version 2021.2.0 because I want to conduct a online study in Naodao.
