Videos dont progress after playing (case 5526)

[Paolo]

Hello,

I have the same problem with MediaLab 2010.2.19 both on Win XP and Win 7. I need to show a video but every time I try it, it goes till the end but then it won't progress.

Another problem I have (again with 2010.2.19 both on Win XP and Win 7) is that the duration parameter does not work If I set for instance (d-180) the continue button does not appear on the item after 3 minutes (if I set that parameters; it will never appear), any idea why I am having this issue? Because of it, I can't set a movie as background video in an instruction item with a duration parameter (as an alternative to the fact that video does not progress).

Thanks for you help -

Best,

Paolo

Hi Paolo,

Please try using MediaLab v2010.3.102. You can download it here

http://empirisoft.com/download_old.aspx

Make sure that you uninstall MediaLab v2010.2.9 before you install MediaLab v2010.3.102. Just email us as before for the install code.

Please do follow up and let us know if that works.

Cheers.

Hi kurosakilo!

Do your videos play normally in Windows Media Player?

I have been trying my ML2010 to play video files properly but failed. Not sure what is going on.

What is happening is, after playing a video file, MediaLab 2010 won't move on to the next item. It will stop, displaying a small square on the screen (see image file attached). Only after I use the hidden control key (ctrl + right arrow), it will move on. But after playing the next video clip, it will do the same.

I have two systems (1: Win XP SP3, 2: Win 7) running the latest ML2010 (ver. 3.1). Both are doing the same.
Video files I have tried using are .avi and .wmv -- both doing the same thing.

I am also attaching the Questionnaire file for you to review. Though nothing fancy here, I am suspecting that parameters (which orders the system to shoot out TTL signals) *might* be playing a role here. I am not sure but even if it was the case, I do need those TTL so I cannot give that part up.

Any suggestions are welcomed. Thanks in advance!

raypark70,

Try renaming your video files without using anything but numbers and letters. I wonder if starting the file names in the filename field of your three movie items with a . and using backslashes in the name may be the problem.

Thanks for your suggestion, Jason. I did try doing that, but the result was same.
As you already know, ".\" refers to 'current directory (folder)' in DOS, which Windows inherited.
Ergo, ".\2D\FileName" = "2D\FileName"
Nevertheless, I was wondering if that may have been the case since it has been quite a while since DOS was released. But it was still working that way.

I also tried moving the video clip to the same folder where the questionnaire & experiment files are & edited the script. Problem persists.

My theory is that after ML calls Windows Media Player(WMP) & completes playing the video, somehow WMP fails to terminate and stays as a thumbnail. I just do not get why & how this is happening.

One possibility is the operating system not being U.S. version (both systems, Win XP and Win 7, are Korean Windows released by MS Korea). However, ML2008 did not have this problem when I executed a similar experiment (lots of video files played) on a Korean Windows XP (SP3) machine three years ago.

Using the questionnaire file I uploaded, can you replicate this issue with ML2010 v3.1 at your office? And even better, can you try to replicate this with ML2014?

Thanks!
