usb_cam Exit code -11

edit

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.
