Videos dont progress after playing (case 5526)

[jarvis24]

I need to preface this with an admission that I don't know why this would be happening unless Microsoft changed the communications from Windows MediaPlayer. MediaLab counts on specific event messages from the WMP in order to react accordingly--like proceeding to the next item.

Until we find a solid fix for this, I can suggest a few work-arounds.

1. Place a duration on the item that is approximately equal to the length of your video so that MediaLab can advance when the duration has lapsed, e.g., a parameter value of (d60) for 60 second video.

2. Embed the video within a PowerPoint file that is set to end when the clip ends. And then present the PowerPoint instead of the movie itself.

3. Call the Windows MediaPlayer (mplayer.exe) as an Executable item from MediaLab and pass it the name of the video file as a parameter. When it ends the user could continue on via the continue button in MediaLab. If this option interests you I can elaborate if need be.

4. Embed the video with an HTML item that would allow the subject to click continue at the end of the video.

Just some initial thoughts, but like I said, we'll also look into why this might be happening with Windows 7. Would be curious to hear if anyone finds the same thing on Vista or XP (loaded with a newer version of WMP perhaps?)

We were able to replicate the problem and I think we found the problem. It should now work on Windows 7 as it always has on XP and Vista (i.e., automatic continuation). Try uninstalling your version of 2008 and installing this newer (Nov 3, 2010) release:

Please let me know if it helps!

Update: Issue resolved as of January, 2011 in MediaLab v2010. As of today, Feb 25, 2011, v2010.2.19 is available on the main download page.

I experience exactly the same problem here on a Windows 7 system, using the MOVIE item type. I even tried the duration parameter (I have a 30 second video, so I used "(d3)&quot, but MediaLab just won't progress. Any chance that this can be solved?

I experience the same problem as well. The movie plays just fine but when the movie is finished the screen just goes to the regular medialab background with a blank, black rectangle in the center of the screen. I use windows vista and medialab 2010.3. I have tried the duration parameter but Medialab does not continue either. I am playing an avi file, in the 'movie' selection type.

Still have the same problem with v2010.2.19. A workaround is to show the movie as background video in an instruction item with a duration parameter (to suppress the continue button).

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
