... I think mex-files work, but I've never tried it myself, since I see Octave primarily as Octave, and not Matlab without a price tag ... So if your code...
The octave->mex interface in octave 3+ works very well. That's how we do it with ptb, we just recompile the matlab mex files as "octave mex files". We only...

Update: I downloaded GStreamer (x86), but no success there, even after using Screen('Preference', 'DefaultVideocaptureEngine', 3); % GStreamer=3, Quicktime=0 ...
Sebastien, I've had decent success with Xkeys. http://www.piengineering.com/xkeys.php Specifically, I've used the foot pedal version as a "big button" response...

All right, another update: I'm not too sure if GStreamer (vs QuickTime) is the route I want to go, but I uninstalled and reinstalled it and got a new set of...
... Yep. You probably just installed a wrong version of GStreamer, which doesn't contain the needed codec plugins. You'll need the GPL version, not the LGPL...
Hi everybody, again, I have to apologize for a very long delay since my last post on this topic. However, this was merely due to the fact, that the pre-warping...
Thanks very much Jurnell for your answer. Finally, we will probably get the response time box (http://lobes.usc.edu/RTbox/). It seems to be the best...

You are providing seriously too little information here for us to say anything about your issue. What are the differences? Please describe in detail. Are you...
Hi, Thanks for the reply. I've been using FillOval however I am not sure how I can adapt this to make the circle oscillate. I presume I may need to use a for...
Hi, I've been getting errors while trying to use 'getchar' in psychtoolbox which I believe is common when your java is not fully updated. So I attempted to...
Alan, That is essentially what you want to do. It is also best to pace the oscillations. Otherwise, it'll appear too fast. So maybe adjust the rect every other...
