Hi DCube. I admit that the way this currently works is less than ideal. I haven't had a lot of time lately to dive into this problem, but it's high on my list of priorities to get fixed. The ffmpeg download functionality is actually provided by the…

I don't really have a clue. I did my best to let the player clean up when it can. Playing videos is a heavy operation in the plugins current form, as the frame loading is not hardware accelerated (rendering of the video frames is is). Players like v…

Hi Katheryn, This is a known problem that occurs for some people and is likely caused by a firewall. We are hoping to integrate the ffmpeg.osx in one of the future versions of OpenSesame (so that it doesn't need to be downloaded anymore), but for n…

I also don't think it's possible to render webpages in any of the current backends, but a Qt backend would certainly make this possible, because you could switch between the QOpenGL Widget/context, and other widgets (forms, webpages, etc.). The even…

Hi @pranitharajn, Thanks for reporting this! That's actually a bug if it doesn't honor the time delay that is set. For now you can block this behavior by simply entering something in the script window. Something like if True: pass or even …

You're right, the code is called on each screen refresh, not only after a new frame has been shown. I decided to do it like this in the end because it allows more fine-grained time measurements. That should be changed in the documentation. Regardles…

No I have never seen this before. It indeed seems if moviepy has some trouble opening the video file. Maybe it is corrupt? Grace, have you tried working with different videos, or to reencode the video that causes this with handbrake or vlc? Given th…

Hi Spanne, you can also place files in folders relative to your OpenSesame experiment, if I'm correct (See this function in the documentation). So if you place your videos in a subfolder videos in the folder at which your experiment is located, you …

I am not entirely certain, but I think it is the most likely explanation for delays as long as 10 minutes that Roy experienced. For me it wasn't that long, it only took a minute or 2 before OpenSesame popped up, but I can imagine that on slower comp…

Hi Roy, I think I have found the problem of the slow startup -- I experienced it myself yesterday! What made this difficult to find is that it only occurs when the machine that OpenSesame is running on doesn't have an Internet connection; how many t…

Hi Mariana, Could you still check one thing for me. If you go to OpenSesame's preferences, you see a section called Runner. Can you tell me what your current setting is there? If it is inprocess, does OpenSesame run more stable after you changed thi…

Hi Tatiana, This is weird, because the file it is missing is included in the OS package. Usually these errors are attributable to old OS X versions. 10.7 is quite old and OpenSesame is built on a much newer version of OS X (10.12). Sadly it is hard …

Hi Palacegreen, I am the author of the media_player_mpy plugin. You should be able to do what you want by using the script box that is provided in the plugin if you set call custom python code to after very frame. Have you tried using this? It shou…
-
Hi Roy, I have the luxury that I only have machine's with SSDs at my disposal so I can't really test the opening speeds on data carriers with lower throughput capacities such HDDs. The fact that you run OpenSesame from a USB drive may definitely be…

In case you are using media_player_mpy, there is an option to 'Fit the video to screen'. If you set this to 'no', the video should be displayed with its original pixel dimensions.
-
Hi Dusty, the video player items work a little bit differently than the other OpenSesame items. If you set the duration to 0, the video will not play at all! To collect responses during video playback, you need to use the script box of the videoplay…

Hi Hike, Thanks for reporting this. I've added an issue on OpenSesame's issue tracker, and we will look into this. Good choice to print the numpad enter key's output. In the meantime you can use that to listen for its presses, but this should be fi…

Thanks for pointing that out Eduard. I indeed started working on such a function, but never got around to really implementing it. The example function should provide a good start and should work out of the box, although newer versions of OS might ha…

Even though this behaviour is weird, it should be possible, but it depends on which backend you're using. Are you using legacy, expyriment or psychopy? Are you running your experiment full screen by the way?
-
Alright, I think I know what's causing this. I'm creating a new package as we speak and will upload it soon. Hopefully it will solve this problem.
-
Hi Zimtschnecke, We removed the parallel item because it was very unstable and caused a lot of crashes or other unwanted behavior. Maybe you could elaborate a bit on what you are trying to achieve, because it is not entirely clear from your descript…
-
Hi Noa, You actually don't need to write any code to show movies in OpenSesame: You can simply use the media_player_mpy item. There should be an icon for this item in your item toolbar and you can drag this icon into your experiment tree (at the poi…
-
Hmm, I've seen this before. What image type (jpg, ping, etc) are you trying to show? It could be that one of these libraries didn't get packaged correctly.
-
Hi Roelof, I'm just wondering why you install pyqt4 with pip, and not simply with conda. Moreover, since pyqt4 is a dependency of qscintilla2, it should already be installed automatically with the first command. Is there any reason why you explicitl…

Hi DCube, others have also reported this problem. Can you see if the solution posted on this thread helps you?
-
If it doesn't work, can you please tell me what goes wrong? I need more information to know where I should look. If the blank scren occurs after the video, then you can place it as a separate item behind the video item. You can control whether the b…
-
Sure! I tend to easier keep track of the things on my plate by using Github's issue tracker. With the forum this is a bit harder. Could you add this issue to the relevant Github repositories and mention or assign me to them?
-
Right, then I made a mistake in my last post. You should set call custom Python code to after each frame and set timeout to 2500 ms. If my code is correct, it should only do something if a key is pressed.

Hi guys, Yes, audio playback is a disaster on mac, and this is all due to the pygame libraries being a mess; especially since the update to MacOS Sierra lately. I somehow managed to get sound to work for media_player_mpy by addressing the pygame.m…

Hi NikkieK, I think I see what is going on now. The way you've set up your experiment indeed causes the experiment to pause at the keyboard_response item. What is happening is that when you press a key during video playback, this is registered as th…
