Video buffering issue

[th3rav3n]

Hi there,

I've used E-Prime extensively in the past and am currently running version 2.0.8.90 on my computer. I want to display 10-15 video clips (.avi) that are of different lengths (no longer than 1min) after a specific image; some of the smaller videos (~2secs) seem to work fine, but anytime I try and run anything longer, I get the following error:

The operation to load the sound timed out
Size: 384000
Available: 364800
Duration: 139665270
BufferFull: 384000
Presented: 364800
Presenting: YesWorking: Yes
TimeStart: 24291
TimeOut: 34292
TimeFirstPresenter: 24545

Line: 352
Error Number:-999

It seems to indicate that there is a video buffering issue, but I've never worked with video files before and am uncertain how to fix this. Can anyone help me out with this or point me in the right direction of things to try?

What OS?

Earlier versions of EP2 were known to have problems presenting sound
& movies under Windows Vista & 7 (e.g.,
https://groups.google.com/d/topic/e-prime/xvCq8uq_T5c ,
http://support.pstnet.com/forum/Topic2760-12-1.aspx ,
https://groups.google.com/d/topic/e-prime/Gg67RCJqqQU), but those
problems were supposed to have been ironed out by EP2.0.8.90. In any
case, you might consider upgrading to EP2.0.10.242, although this may
affect other experiments (see PST's own warnings). Or, use Windows
XP, all of these things seemed to work pretty well under XP.

I'm using Windows XP and am having this problem. Some of the smaller video files seem to work fine (~2-4secs) but none of the larger ones.

Any update on this? Using XP and Eprime 2.0.8.90 -- cannot upgrade to newer version of Eprime because of timing issues related to Eprime Extension for Netstation. I downloaded FFDShow and the videos render properly in Codec Config (they are AVIs) but after a few blocks 3-5 I get the same error message (see image). Note I'm only playing 2 videos (around 1600 ms each) interchangeably.

Hi,

This is an informal group, rather than an official support forum, of volunteers, rather than employees – just to point out that one doesn’t always get response. I think in general, people don’t feel obliged to respond to ill-formulated questions to which they are required to fish for more information – unless the solution is extremely straightforward.

 

In any case:

·         AVI is not a codec, it’s a container format. That means that virtually any type of compressor could have been used (e.g. divx). In other words, it’s about as useful as saying I’m presenting an image (they are PICTURES).

Diagnostic steps:

·         Have you tried: running the experiment on a different computer?

·         With a new E-Prime version (yeah, I know, Netstation can be a pain like that, but do press them to update their software!) on the same computer? It’s helpful to diagnose whether the problem is an old E-Prime issue.

·         Have you tried using the same videos in a different “known to work” experiment? (like the sample video experiment)

·         Have you tried re-compressing the videos to some other codec? There are many that pretty much always work.

 

If you go through these steps, the chance is pretty high you’ll find out what’s the problem. Let us know if you do!

 

BTW: the original “th3rav3n” problem seems to be inability to play long videos – the current issue seems to be short ones instead.

 

Hope that helps!

Best,

Michiel

Ah, the old "sound timed out" error, if you search the Group for that
you will find other threads that explore it. We used to get that all
the time when running sound or video with EP2.0.8 under Windows Vista
or 7, but never with Windows XP, so I have no ideas to help you, just
passing along this bit of background information. PST seems to have
fixed this in EP2.0.10, but as you said you must stay back at EP2.0.8
to work with the Netstation Package. Sorry. You might try
contacting PST Support.
