Can't stream from Raspberry pi to another PC where pupil capture is running #7

Hello, I have pupil core product with world camera and eye0 camera. I am trying to use pupil core with raspberry pi. Raspberry pi is just for the streaming video over WiFi to another PC where pupil capture is runnig. When I run the main.py on raspberry pi, I get nothing from other PC where pupil capture is running. I could not figured it out. Any idea about this problem will be perfect for me. Thanks

Hi! I have resolved it ! Are you using debian 11 bullseye? I found that this version of Raspberry Pi does not support libcamera, you can downgrade the system. After I used buster, everything became normal.
