Hi BrianHouse
Do scripts that don't utilize the color camera work? e.g. Mono preview
Thanks,
Jaka
Video Window Does not render
Yes all scripts referencing the right and left mono cameras work perfect. Just the RGb does nothing.
Specifically I have been trying to compare and contrast the rgbpreview.py (that does nothing, generates no errors but does not even render a black window) and mono_preview.py that does work. I am trying to debug these variables in pycharm:
xoutLeft = pipeline.create(dai.node.XLinkOut)
According to the hellow world example provided in the documentation, this is where the camera gets 'added' whether it be RGB or Monjo. I am trying to figure out what is different with the camera that works and the one that doesnt.
Anything specific I could look at to determine where the issue may lie.
I was looking at the connection attribute but is says 'None' for the value for both cameras so that is not a good indicator why one would work and one would not. Any variable specifically I could set a debug 'watch' to shed more light on this?
Hi BrianHouse
I feel like the XLink for color just isn't sending frames to a queue correctly. When reading from the rgb queue with .get() the script probably blocks, since there is no frame to be read and .get() is a blocking function.
I believe since you are running all the latest versions of software, it might be a hardware fault.
Could you:
- try to run the pipeline graph tool to see where the stream stops
- try the same script with the same camera and usb cable on a PC to confirm
Thanks,
Jaka
Hi BrianHouse
Sorry for not linking to the repo. Here.
Run it using pipeline_graph run "python3 <name of script>.
Thanks,
Jaka
thanks
Here is the output from first running mono_preview.py which does work:
(base) Brians-MacBook-Pro:examples brianhouse$ pipeline_graph run "python3 MonoCamera/mono_preview.py"
Pipeline schema retrieved
Program exited.
0. MonoCamera.out (10) -> XLinkOut.in (2)
1. MonoCamera.out (6) -> XLinkOut.in (1)
Here is the output from rgb_preview.py which does not work:
(base) Brians-MacBook-Pro:examples brianhouse$ pipeline_graph run "python3 ColorCamera/rgb_preview.py"
Pipeline schema retrieved
Program exited.
0. ColorCamera.preview (8) -> XLinkOut.in (1)
Hi BrianHouse ,
We apologize for taking this long to debug.. Could you just try the last thing, the cam_test.py, and copy the terminal output? My guess is that ColorCam is connected, but will stream 0 FPS, which means the cable isn't properly connected on the PCBA. In such case, we will replace the device asap.
Sorry again!
Are there other modules I am going to need"?
(base) Brians-MacBook-Pro:tests brianhouse$ python3 cam_test.py
Traceback (most recent call last):
File "cam_test.py", line 45, in <module>
import cam_test_gui
ModuleNotFoundError: No module named 'cam_test_gui'
(base) Brians-MacBook-Pro:tests brianhouse$
also I noticed it has a lot of options which ones do you want me to run?
ok, I figured out all the dependencies. I have Camera Test working. I guess I take all the defaults to the prompts and 'connect' to the device"?
Here is the output:
(base) Brians-MacBook-Pro:tests brianhouse$ python3 cam_test.py

Hi BrianHouse
Yeah, seems like a connection issue on rgb (note the 0 | 0 on rgb). Could you write to support@luxonis.com, so we can replace the camera.
Thanks and sorry for the inconvenience.
Regards,
Jaka
Sure thanks for all your help Erik and Jaka!

How long did it take to get your replacement?
Another one with the same issue. Super frustrating way to run support on a forum!

Hi Adam,
I have not received it yet. I also asked them for tracking info which I have not received yet.
