Hi, I'm really new in ROS(I started a year ago, though), and I have a question using usb_cam package.

I'm working on using purethermal1 with Flir Lepton 2.5,

and launched usb_cam-test.launch file, but the process is failed with exit code -11.

There're some WARNINGS, but I think nothing is related to process failing.

I dont know what causes exit code -11, so I ask question here.

But it's OK when I try same process with logitech webcam.

So, my question is,

Do you guys have recommanded ROS Package to watch thermal cam?

I'm using UBUNTU 16.04, ROS Kinetic

I insists ros because we need raw data in ros message to another processing procedure.

I hope cool advice, thx.

And really sorry for my short English.

Never mind with this question. I found myself.

Just using usb_cam package, which is already included ROS system.

The important points are pixel format and width, height.

In purethermal1, pixel format is uyvy, 80 x 60 resolutions.

Just modify that parameter in launch file.

and do the roslaunch:

sudo chmod +x /dev/video0

roslaunch usb_cam usb_cam-test.launch

And everything works fine.
