NA Invalid path to video file: NA (file not found)

Mikefiels

Hello all,

 I want to display videos using OpenSesame 3.9, and to do so, I have an initialization script and an in-block script followed by an mpy object. All the videos are uploaded into the pool and defined in a list under the name videos_by_animal_con. Unfortunately, I get the following error after a couple of iterations or sometimes right from the beginning:

NA (file not found) or An Exception occurred during exp.end(): 'Decoder' object has no attribute 'audioformat'

Invalid path to video file: NA (file not found). Does anyone have any advice on how to resolve these errors? 

thanks ,

mike

Hi mike,

I can't tell you what is happening, but what you could try to narrow it down is following:

Remove randomization of trials, which will tell you whether the error always happens at the same time, or varies. You can also print out the current filename before loading the video, which will tell you whether there is any rogue filename.

Hope this helps,

Eduard
