issalig Posted July 14, 2016 Share Posted July 14, 2016 I am using legacy Armbian_5.14_Orangepi2_Ubuntu_xenial_3.4.112.7z and a Logitech C110 and I cannot set some params. However I can set this in my PC under x86_64 3.13.0-91-generic. Below is the output of v4l2-ctl in orangepi2. Any idea? $ v4l2-ctl -l --verbose VIDIOC_QUERYCAP: okerror 22 getting ctrl Brightnesserror 22 getting ctrl Contrasterror 22 getting ctrl Saturationerror 22 getting ctrl Hueerror 22 getting ctrl White Balance Temperature, Autoerror 22 getting ctrl Gammaerror 22 getting ctrl Power Line Frequencyerror 22 getting ctrl White Balance Temperatureerror 22 getting ctrl Sharpnesserror 22 getting ctrl Backlight Compensation exposure_auto (menu) : min=0 max=3 default=3 value=3 exposure_absolute (int) : min=2 max=5000 step=1 default=312 value=312 exposure_auto_priority (bool) : default=0 value=1 pan_absolute (int) : min=-72000 max=72000 step=3600 default=0 value=0 tilt_absolute (int) : min=-54000 max=54000 step=3600 default=0 value=0 zoom_absolute (int) : min=1 max=2 step=1 default=1 value=1 Link to comment Share on other sites More sharing options...
