Loading camera settings from a file

[dmrokan]

Hello,

I am trying to take photos from a web cam (Logitech c920) with manually selected exact camera settings. I am loading configuration file with --config flag.

device /dev/video0
delay 1
skip 20
jpeg 80
resolution 1600x896
no-banner
set "White Balance Temperature, Auto"=False
set "White Balance Temperature"=6500
set "Focus, Auto"=False
set "Focus (absolute)"=72
set "Exposure, Auto"=False
set "Exposure (absolute)"=215
set "Gain"=1
frames 1

I think these setting are not loading correctly, since I get different results at every try.

Is there a missing configuration parameter? Or is it a hardware problem?

Thank you

Edit:

Taking a few pictures before adjusting camera settings solved my problem.
Additionally, setting -S (frames skip) argument a large value (100 for my case), gives absolutely stable results.
