Strange. Just to be sure, you are using OpenSesame 0.27.4 and this only occurs with old experiments, not with newer ones? I have not enough information to go on, to really pinpoint what causes the problem here.
-
Hi Starr, It could be that you have a newer version of libfreetype installed, which OpenSesame can't find as it is looking for the older version. Normally all dylibs in mac are symlinked to with a version agnostic link like libfreetype.dylib (note t…

Hi Kristylen, Could you check in your /usr/X11/lib/ folder if there is a libfreetype.6.dylib file, or a file with a similar name but a higher number than 6? If so, could you mention here what name the file(s) have?

I don't think the vlc player works at all on the mac, and the videoplayer that is included is based on opencv, which is also a bit dodgy.You can try using the GStreamer video player instead: https://github.com/dschreij/media_player_gst This requires…

Hi MasterThesis, I know a trick, but it's not really an elegant one as it only works in the psychopy backend, and therefore you can't use the legacy or expyriment backend anymore after you implemented it like this. Nevertheless, here is how you can…

I did indeed test it on Windows 7 and on Windows 8 it also appeared to run fine (although I just tested this shortly). If you go to system properties and then check your environment variables, is there an entry of the GSTREAMER_X86_SDK_ROOT? Where d…

Hey there. Sorry for the long wait. I did some short tests on OSX and video playback appeared to be fine (still less good than on PC and Linux though). I've looked through the crash report and have no idea what caused this (the only useful info tha…

You should not need to manually add the os.environ["GSTREAMER_SDK_ROOT_X86"] = "C:/gstreamer-sdk" line if the gstreamer framework is installed correctly. The installation process should automatically add this entry to your envi…
-
Hi Joshua, when you install the GStreamer SDK it should automatically create the environmental variable GSTREAMER_SDK_ROOT_X86 for you. If this has not happened, something probably went wrong with the installation. Manually assigning this viarable …

I really like it! The ergonomics of this sketchpad are already far superior to the previous version. :)
-
Hi Timo, this is a well-known and dodgy problem of the vlc plugin and worst of all, it differs per system/video-card vendor. I've not been able to fix this problem, mainly due to the closed nature of the vlc bindings, which operate on very low-leve…
-
Hi Sebastiaan, thanks for the further input! I'd be happy to dive into enhancing the QTableWidget/good_looking_table functionalities. What is the best way to start this as a standalone project. Just start afresh while following conventions that mak…
-
Does it occur both with wav and mp3 recording? Both of these modes use completely different python modules to do the heavy lifting, so it might be that the other mode which you are using does not suffer from the problem. If it occurs in both modes, …

Hi Shinae, You may try to download the latest version of the plugin from https://github.com/dschreij/media_player_vlc and see if it helps. You might also try to replace the vlc.py included with OpenSesame with the one from http://git.videolan.org/?…

Hi Gerardo, of course, you're right. I forgot all about a conversation a while ago with the SR helpdesk during which they built a custom pylink module for me. It is weird that they haven't implemented these changes of my custom module in the main v…
-
Hi Gerardo, I've been trying to find an appropriate experiment, but most I have readily available involve large image sets which I can't easily send along. I will try to create a simpler experiment that uses backdrops and see if it works here before…
-
Hi Matt, As far as I know, OpenSesame does not have this function. The installer of OpenSesame me is made with NSIS (from Nullsoft) so if it has nativesupport for this flag, OpenSesame will probably too. By the sound of it, the portable version of …
-
Hi Svetlognev, What do you mean with blocked? Does it freeze up on a specific frame, or do you see a blank black screen and the experiment simply does not continue upon a keypress? These kinds of random freeze-ups are always really difficult to ad…
-
Great idea and I already Agree with @Edwin and you on your variable management points. I have some suggested improvements of my own for existing OpenSesame procedures and interface widgets. These suggestions partly overlap with the other 'wishlist'…
-
I also had such problems here. We have several Eyelink installations, some of which are also of different models and makes. The backdrop functionality is a really 'iffy' feature of the Eyelink software, which is also badly implemented (sloooww!). Be…
-
Hi Gerardo, last time I did it, this experiment structure worked: (Image) in stimulus_display, I create a canvas in the prepare phase and when I have finished drawing I prepare it as a backdrop image with the following line at the bottom of the …
-
Hi gerardo, You need to call the set_backdrop() function before you have called eyelink.start_recording() or before the eyelink_start_recording item is executed. Somehow the backdrop is not shown if you call the set_backdrop() function during recor…
-
Did you download the version with pymedia included? It sounds as if you just downloaded the version with the bare plugin as vcodec is a part of pymedia and it appears to miss this. Next to this, are you running from source, or using the distributed …
-
Add the item to display on an erroneous response as normally, but in the sequence, set the Run if.. of this item to [correct] = 0. Below is an example to illustrate this (Image) Here a sound is played (through a synth item) and a red fixation d…
-
Hi Mariosav, make sure you don't have the placed everything in one folder such as "opensesame_soundrecorder_plugins" of which sound_start_recording and sound_stop_recording are subfolders. You need to place these two folders directly and …
-
Hi Baldrick, I've looked into this and noticed that the mute option is indeed broken. The problem however appears to originate from the python bindings for vlc and not in the plugin code. These bindings are really old (the last update was July last…
-
Hi sdg, I am going to give you a short answer and a long one. The short version: The version of OpenSesame you are using is very old, so i don't think any of those plugins are going to work anyway. The best solution for your situation would be to …
-
Yeah, the event detection system is not really well implemented for the vlc plugin. I will have a look at it soon. It however is tested and it works for the gst variant of the media_player, so you might want to try that!
-
Hi Joshua, it is not yet possible to play video's in OpenSesame on an android device. We hope to implement this in the near future, but I cannot say when we'll get to it.

This rather appears to be an error in QProgEdit to me. Are you running from source? If so, update that package by getting the latest version from https://github.com/smathot/QProgEdit and try again. Let me know if it works.
