I tried commenting out scanning_modes
in the cfg file and camera_driver
, but then it is auto_exposure that takes on bad values and crashes rqt dynamic reconfigure.
If I disable about half of the cfg then rqt doesn't give the bad value error, but none of the controls work- this is in the form camera_driver.cpp:132 : Unable to set brightness to 10
.
Has anyone found a solution to this? I believe I am having a similar issue. Attempting to set brightness or exposure absolute at all causes an immediate failure on one camera, on the other it only crashes if i try to use any value other than the default.
This is still an issue in melodic
I've been trying the very latest libuvc and libuvc_camera with ros jade on Ubuntu 14.04 and either a Logitech C930e or a Webcam 9000 Pro and I can't reconfigure the camera. The scanning_mode initial value is very large and often negative, and appears random on every launch of the camera_node. Trying to change most other parameters triggers an attempt to set scanning_mode to a sane value which fails- and sometimes makes the setting of the other value fail.
rqt_reconfigure doesn't like the big numbers and generates a ValueError.
I have more details here:
