Error message when dragging media_player to experiment

juliakers10

this is the error message I receive when dragging the media_player_mpy to my experiment.
Does anyone know how to fix this?

Error message:

Hi Julia,

The media_player_mpy automatically tries to download a library that it needs to play back video. And apparently this fails on your system. But it's not clear to me why.

What happens if you execute the following two lines in the debug window?

from imageio.plugins import ffmpeg
ffmpeg.download()

Could you post the output that you see after executing these lines here?

Cheers!

PS. I noticed that you opened several discussions and posted several comments about the same/ related question(s). Please don't! By sticking to one discussion per question, you help us keep the forum clean and useful.

Here it is.
Thank you.

Sorry I believe the image didn't upload.

Right, it seems that you first need to update imageio (I was using a more recent version). To do so, open Menu → Tools → Python package manager, search for imageio, right-click on it, and select 'Update'.

After you've updated, what happens if you try to execute these commands in the debug window again?
