Hello,
I am using this example: https://github.com/STMicroelectronics/x-cube-n6-ai-h264-usb-uvc
HW: STM32N6570-DK + STEVAL-66GYMAI
I have this strange behavior only when using the VD66GY. If no motion on the video, i barely see the flickering. However, when i do a little motion in front of the camera, I begin to see white horizontal lines on the of the video stream, this flickering happens only at around 30fps. Only when I reduce to 15fps it disappears...
Also lowering the VENC resolution did not fix it.
#define VENC_VD66GY_WIDTH
#define VENC_VD66GY_HEIGHT
BTW, The IMX335 works fine at 30fps.
Can someone help me ?
Thank you.

I think it may be related to the external PSRAM.
Any idea how to fix it ?

Hello FB__1,
I'm not aware about this issue coud you post here :STM32 MCUs Products - STMicroelectronics Community
the issue seems more related to the management of STM32N6 than the camera himself
thanks,
bye
