• Video Window Does not render

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

      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"?

              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"?

                          Another one with the same issue. Super frustrating way to run support on a forum!

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