media_player_pny plugin error

franb123

Hello, and thanks for Open Sesame.

I am a new user with little-to-no Python knowledge. I am having difficulties using the media player plugin. Every time I drag and drop a media_player_mpy item into my experiment it results in an error message (see bottom).

Other users have reported similar problems. However, the recommendations don't work for me:

• I have tried using different internet connections/networks - still get the same error message
• I have downloaded the ffmpeg.osx file and tried to follow advice to manually copy it into the /Users//Library/Application Support/imageio/ffmpeg location. My 'Application Support' folder (which is in a slightly different location to this address) did not have an 'imageio' folder in it. I created one - followed by a 'ffmpeg' folder - and put the file ffmpeg.osx in it. I still get the same error message.

I am using OpenSesame is 3.1.9. I have tried uninstalling and reinstalling this version. I have also tried an old version (2.9.7) which seems to use a different media player plugin and also results in an error message. My operating system is macOS Sierra 10.12.1.

Any help appreciated. Here is the full error message:

@Daniel Do you have any idea where this comes from, and what can be done about it?
