Unable to capture image in E-CAM80_MI8825_MOD E88E0025 camera about qtcam HOT 3 OPEN

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?

from qtcam.

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

from qtcam.

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.
