Multimedia Capabilities

Heidi_Schaefer

Hello,

I am writing to inquire about the possibility of using OpenSesame for a neuroscience study.

For the presentation of stimuli, I need the ability to show 4 videos simultaneously on the same screen. For the testing portion, I need multimedia capabilities on the same screen. In some cases I will need to present several audio clips which the participant can play at their own rate. In addition, I may need to have several video clips playing simultaneously, while still retaining the ability to play the audio clips at the same time.

If all this is possible, does anyone know of any similar experiments that other labs have done so I could contact them?

Thank you so much for your help,

Wow, sounds like a complex and ambitious paradigm. Technically this should be possible (you'll need a powerful pc though!) but OpenSesame cannot do this yet. I'm planning on rewriting the gst-player plugin to support multiple video outputs on the same screen, but this will itself also be an ambitious project. I can't promise anything on when I have this done, so for now I cannot satisfy your requirements. I also don't know any labs which have done experiments like this. Maybe someone else does?

You could use opencv to read and play video files. This will give you a lot of flexibility, including control of speed and the possibility to show multiple videos at once. But it will require a fair amount of Python coding. As @dschreij says, this is not something you can do using the OpenSesame GUI.
