I can't get images in full resolution on a raspberrry pi 5 with ubuntu 22.04.

I only get imageas with half resolution.

I used my own code and also SpinView QT.

I have tesed with different image sizes and image greater than 5472x2048 pixels failed in my code with the message:

Failed waiting for EventData on NEW_BUFFER_DATA event.

Has anyone tested this or have an idear how I can solve this problem?

Thanks,

Achim

  Hi Achim,

  Did you set the USBFS memory to a higher value?
  Could you please try to follow the the section "USB CAMERA SETUP" in the README_ARM file included in Spinnaker package?

  Please let us know if this helps.

  Best Regards,
  Markus

  Hi Markus,

  I increased the USBFS memory in 1000er steps up to 7000. And have done everything from the readme file.

  I have tried to minimize the number of buffers to 3 ( by setting the buffer handling to manual ) and check if the result is 3. But also with only 3 buffer I get no image.

  I seems to be a problem with the calculation of the memory for the buffer. When I have only 3 buffers ( the maximum value of buffer are about  over 200 ), there must be enough memeroy for the images. One image is only 20Mbyte, so 3 images are 60 Mbyte. Also when there are some overhead, a USBFS greater than 1000 must be enough for 3 images.

   

  But I have no idear how I can check the buffer size or how I can affect the size of the memory used for one buffer.

  The things I read ( increase USBFS and reduce the number of buffers) has no effect on my problem.

  Best regards,

  Achim

  Hello Achim,

  Would you mind opening a support ticket at https://flir.custhelp.com/app/ask ?
  I think we have to have a closer look at this and maybe do a remote session.

  Thanks,
  Markus

  Hi Makrus,

  yes I will open a support ticket for this problem.

  This can take a while, because now other projects have a higher priority.

  I thought that only the supoort can help me, this forum was only a quick try to get a solution.

  Thank you for your help.

  Best regards,

  Achim
