camera_calibration runs but cannot calibrate [closed]

Hi all, I tried to calibrate my Firefly MV Firewire camera with the provided ROS Indigo package. So I ran roscore and camera1394, and then the command on the wiki.

The wiki says that to start the calibration I have to press the Calibrate Button but it is gray and nothing happens when I press it.

Anyone can help me?

I use Ubuntu 14.04 and ROS Indigo.

This is the command I ran:

rosrun camera_calibration --size 8x5 --square 0.030 image:=/camera/image_raw camera:=/camera

You have to collect the samples first, then the the 'calibrate' button will be enabled

If you already collected the samples, and are pressing the calibrate button after, it does take a super long time for it to actually finish creating your calibration parameters (i sometimes have to wait close to 8-10 minutes). The more samples you have, the longer that the calibration will take. Im not sure if this is actually just a bug or not, but i do know that it used to not take this long (i cant remember when 'used to' exactly was, but i think back when i used hydro). It doesnt seem like there is a issue on the camera_calibration repo about this considering how long i myself have encountered this super long wait time.

If you could, just try doing the bare minimum to be able to click the calibrate button (so least amount of samples you can get) and wait just a bit (5-10 minutes) and post here if you could actually get the calibration to be produced.
