I have v4l drivers installed, when I try capturing qtcam gets hanged.

I have also tried with command line utility fswebcam which uses v4l driver directly this the error received

fswebcam -d /dev/video1 img.raw --- Opening /dev/video1... Trying source module v4l2... /dev/video1 opened. No input was specified, using the first. Adjusting resolution from 384x288 to 640x480. --- Capturing frame... Timed out waiting for frame! No frames captured.

Hi, We are able to capture the image using "qtcam" and "fswebcam". We are using ubuntu 16.04. Can you please send the below details.

  1. Are you working in desktop or any embedded board?
  2. Which Ubuntu version are you using?
  3. Which firmware version are you using in the camera?

I am using laptop ubuntu 16.04.5 Firmware version I have no idea

I tried debugging more, I used uvccapture to capture I got the error "ioctl querycontroll error 22" further debugging I got to know there is some invalid argument is being passsed

Please try to use the latest firmware for this camera from developer website with Qtcam.

Regarding uvccapture, There will be shortcoming. Please refer the link http://christian.kuelker.info/doc/uvccapture/uvccapture.html.

I am able to capture the image using the command $sudo uvccapture -S40 -C30 -G80 -B20 -m -x1920 -y1080 -v -t1

This command will take a shot 1 second once and generate a file "snap.jpg". Please stop the application after 3 or 4 seconds and check "snap.jpg" file. If we use single shot mode, we observe that the frame will not be saved properly.

I hope this will help you.
