I have gone and completely retraced all of my steps in setting up my environment so hopefully something can be uncovered. Here is my full walkthrough of my setup, which I have done in a new directory as to ensure there is no previous conflicts:
Context for machine: Python 3.10.11, Windows 11, running all prompts via CMD (non-admin mode).
Started new folder in Documents directory.
Followed install steps for windows (https://docs.luxonis.com/software-v3/depthai/) for DepthAI v3:
git clone https://github.com/luxonis/depthai-core.git
cd depthai-core
# Create and source venv
python -m venv venv
.\venv\Scripts\activate
# Install requirements
python examples\python\install_requirements.py
Oak-D-Lite was plugged into desktop via USB 3.0 cable (in Blue USB3.0 port).
Windows USB connection noise pings.
Followed and ran example code steps on same DepthAI v3 page (I used the camera_all.py example):
cd examples\python
# Display all camera streams
python Camera\camera_all.py
Windows USB connection noise pings once again.
Camera feeds all show with effectively no latency or delay in picture / video quality. No issue during streaming for any amount of time (ran for most 10 mins just to see).
Left-Click on Display window and press 'Q' on keyboard.
Windows USB disconnection noise pings.
Images and video streams freeze for maybe 5-10 seconds before disappearing.
Without DEPTHAI_LEVEL=debug or DEPTHAI_DEBUG=1, no errors or output show in CMD.
When same Camera\camera_all.py script is run again after closing of previous stream, operation seems to halt in CMD and pause for about 10 seconds before it displays:

multiple times in succession before providing error:

In debugging mode, this is that same error:

Error is only resolved and allows camera to stream again after device has been unplugged from USB and replugged.
When camera is unplugged, normal windows USB disconnection sound still pings. Same USB connection when replugged.
When camera_all.py script is run during debug mode after this replug, here is the output with some errors shown. Camera streams all still run without issue to the front-end.
This is the output before the camera streams are closed (it is alot):

This has been my pretty much entire setup with the issue I have been having with my Oak-D-Lite.
Here is the code for the camera_all.py script that I have been running. It was not modified from the initial install of DepthAIv3:
#!/usr/bin/env python3
import cv2import depthai as dai
# Create pipeline
device = dai.Device()
with dai.Pipeline(device) as pipeline:
outputQueues = {}
sockets = device.getConnectedCameras()
for socket in sockets:
cam = pipeline.create(dai.node.Camera).build(socket)
outputQueues[str(socket)] = cam.requestFullResolutionOutput().createOutputQueue()
pipeline.start()
while pipeline.isRunning():
for name in outputQueues.keys():
queue = outputQueues[name]
videoIn = queue.get()
assert isinstance(videoIn, dai.ImgFrame)
# Visualizing the frame on slower hosts might have overhead
cv2.imshow(name, videoIn.getCvFrame())}
if cv2.waitKey(1) == ord("q"):
break
This code was copied directly from examples\python\Camera\camera_all.py via code camera_all.py
I hope this helps in figuring out what is going on with my environment / camera equipment. I was hoping to be using this camera on a robotic arm project of mine. It's inconvenient to test scripts when it has to be reset completely every time. I know now this is not intended behavior, so I am hoping to fix this.
Thank you again for the great help. Any additional information I can provide for this?
