Hi guys,

i am totally new to Qt. However, i have been struggling to get familiarize and improve programming abilities.

I am developing a small app for my image processing project with opencv and Qt, of course.
For last 2 hours i was struggling to get image displayed in one of the Labels. i was getting following error.
Qt Code:
  1. libv4l2: error setting pixformat: Input/output error
  2. HIGHGUI ERROR: libv4l unable to ioctl S_FMT
To copy to clipboard, switch view to plain text mode 

Solution that i found is to remove all usb devices that you don't need and changing the port of the Webcam. Also make sure you webcam is plugged in right.

It seems my laptop ports and giving up :'(

Sometimes small things matter alot!
