Problem with video plug-in in mac os

neo721

Hello,

First I would like to thank the designers of this powerful software!!

I have installed the Opensesame (version 3.1.1) in my mac pro (OSX 'el capitan') recently. But each time when I try to add the built-in plug-in "media_player_mpy" into my experiment, it just showed the error as follows:

Traceback (most recent call last):

File"/Application/OpenSesame.app/Contents/Resources/lib/Python2.7/site-packages/libqtopensesame/widgets/tree_apprend_menu.py", line 182, in append_itemaction.append_item(target_item_name)

File "/Application/OpenSesame.app/Contents/Resources/lib/Python2.7/site-packages/libqtopensesame/widgets/tree_apprend_menu.py", line 127, in append_item target_item.insert_child_item(item.name, len(target_item.items))     A

AttributeError: 'NoneType' object has no attribute 'name'. 

Then I have uninstalled it and download the plug-in again from the website, but the problem remains. I have also tried the other two video plug-ins, but still can not find a way.

This plug-in works perferctly in my laptop with windows system. Waht could be the problem?

Thanks a lot in advance for lending me a hand!

best wishes

Hi Wu,

What you're seeing here is actually a bug in the append-new-item button which hides the real error message; that is, you're seeing an error message that results indirectly from not being able to load the media_player_mpy.

Could you to add the media_player_mpy by dragging it from the item toolbar? Then you should see a more informative message, which you can paste here.

Cheers!
