Subject: Re: [linux-uvc-devel] Question regarding changing settings for a
UVC camera
Hi,
could you post the output of
guvcview --verbose (for versions < 2.0.0)
or
guvcview --verbosity=2 (for versions >= 2.0.0)
Regards,
Paulo
Post by David AliagaDear Sirs.
This is my first message. I would really appreciate your help.
I have a similar problem as the one posted on
http://sourceforge.net/p/linux-uvc/mailman/message/29831756/
or
http://sourceforge.net/p/linux-uvc/mailman/message/29866952/
That is, I have a UVC compliant camera, connected to a Devian linux system.
I used uvcdynctrl and also my own program using V4L2 to change the settings
(in particular the Exposure settings) of a UVC camera.
I set it to manual and change the exposure values (tried very underexposed
and very overexposed)
However after setting these values (and checking that they are set) I took a
pic using cheese, luvcview and my own program.
The image does not change. (they must be underexposed and overexposed)
In the threads I indicated above, there is no solution to this problem.
Does anybody know how can I solve this issue.
Thanks a lot for any help. Very much appreciated
P.S> When I tried luvcview, the image appear unchanged but if I change the
exposure using >that< application, it changes to correctly overexposed or
underexposed.
