Video plug-in on OS Catalina

NathaciaRibeiro

Hi all!

I'm trying to get 4 short videos to run on my experiment, but when I try to put the video player on my sequence it says that it failed to load "media_player_mpy". It says I need to download ffmpeg, and to use imageio to download it. The thing is imageio seems to run only on Python 3 and Opesesame for Mac is only in Python 2.

Please, help ?

Hi Nathacia,

Maybe this discussion can help?

https://forum.cogsci.nl/discussion/2640/troubles-with-media-player-mpy-unable-to-download-ffmpeg-osx

Other than that, I don't know what could be it. Maybe you could browse the forum for other discussion involving the media player on Macs.
