Video Window Does not render

jakaskerl

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?

Where do I find the pipeline graph tool? What do I need to execute it?

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)

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"?

Hi Adam,

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