Arducam PTZ imx477 camera


I have connected arducam 12mp ptz imx477 camera with pi 4 via CSI.

And i’m doing Tensor flow custom trained model for object detection ( fabric defect detection).

libcamera-still commands working with no errors.

Even python script works without fail. But after some time of running defect detection python script/code… i’m getting below error…

[0:57:00.575959433] [6586] WARN V4L2 v4l2_videodevice.cpp:2007 /dev/video2[15:cap]: Dequeue timer of 1000000.00us has expired!
[0:57:00.576077173] [6586] ERROR RPI pipeline_base.cpp:1333 Camera frontend has timed out!

[0:57:00.576116210] [6586] ERROR RPI pipeline_base.cpp:1335 Alternatively, try another cable and/or sensor.

I’m worried about camera sensors… i have changed Camera cable with new one, double checked and i’m sure about cables connected securely. but still same thing happening…

Please help me to get out from this error…

Thanks again.

Please keep the PTZ camera aside for a while and then give it a try.
