Procedure to make the BasicV4L2 work on Nano #2

Open beniroquai opened 4 years ago

beniroquai commented 4 years ago

After calling the make command in the appropriate folder, what are the parameters which should be used to call the BasicDemo?

Is there a step-by-step guide in order to get the Camera running on a Jetson board?

@beniroquai, did you found an answer? It would be great to share as I am also facing the same issue.

Hey, sorry, I cannot remember if I got it to work in the end. Anyway, I use the VimbaViewer which does everything I wanted. Some of the instructions on how to install everything are noted here Hope that helps

Thank you very much for your response. I was of the view point that VimbaViewer also needs driver, but as you say it works, I would give it a try.

Ah, you want to use the CSI-based camera? Were you able to get this running?

krs1980 commented 3 years ago

@beniroquai , thanks again for your response, but I couldn't perform the steps as per the share link. Luckily, I got a way for camera to be detected.

I am still not able to get the camera do what I need for my project. I run the BasicDemo, the output throws an error. Here is the output: //////////////////////////////////////////// /// Basic V4L2 Demo - Version 1.1.0 ////////////////////////////////////////////

Error: No device specified.

Usage: ./BasicDemo [options]

Options: -d | --device Video device name -m | --mmap Use memory mapped buffers [default] -u | --userp Use application allocated buffers -b | --buff Number of buffers ( > 3 ) -l | --left Left (X offset) for crop -t | --top Top (Y offset) for crop -w | --width Width for crop -h | --height Height for crop

I am trying to figure out where I am going wrong. Any help would be a big support.

To make BasicV4L2 work on Nano, we need to specify options through command line. While other options are not mandatory and might be code takes their default value, the -d option has to specify the camera node (/dev/video0 in my case). Simplest way to run the code is: ./BasiDemo -d /dev/video0 Kindly edit video node as appropriate Specify other parameters as appropriate.

It would have been better if the readme.txt mentioned a simple way to run the output file with other arguments to be provided in the command line
