failed to load plugin 'media_player_mpy'


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 tried downloading ffmpeg myself.

I downloaded it at and copied the ffmpeg.osx to applications.

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

I received this message error:

Do you have a solution to resolve this problem ?

Thank you for your help in advance.
