Failed to load plugin 'media_player_mpy'

Hello,

I am trying to include a video in my stimuli in Open Sesame by dragging the 'media_player_mpy' GUI into my paradigm pipeline. However, when I drag it over I get the below error. I did some digging in previous discussion where I tried downloading ffmpeg myself and placing it in the right folder.

I downloaded it at https://github.com/imageio/imageio-binaries/raw/master/ffmpeg and copied the ffmpeg.osx to /Users/<your_username>/Library/Application Support/imageio/ffmpeg So to be clear, the last ffmpeg in this path is a folder, and in this folder you place the file ffmpeg.osx.

After doing this, I closed Open Sesame down, reloaded and tried to drag it over again - I received the same error.

I have my firewall turned off & am attached to a private internet connection. I have both 'media_player_mpy' and 'ffmpeg' downloaded, but Python can't seem to locate them. Does anyone have any other suggestions, or encountered this same issue and fixed it?

Thank you for your help in advance!

Ellie
