Running mjpg-streamer, my pan and tilt controls were not available.
There were lots of errors like
UVCIOC_CTRL_ADD - Error at Pan (relative): Inappropriate ioctl for device (25)
To fix this, make sure that
uvcdynctl are installed
sudo apt install libwebcam0 uvcdynctrl
Running the following command, there are likely no pan/tilt controls present.
Now import the logitech IOCTL bindings
Now, you should have pan/tilt bindings
uvcdynctrl -c Brightness Contrast Saturation White Balance Temperature, Auto Gain Power Line Frequency White Balance Temperature Sharpness Backlight Compensation Exposure, Auto Exposure (Absolute) Exposure, Auto Priority Pan (relative) Tilt (relative) Pan Reset Tilt Reset Focus Pan/tilt Reset Focus LED1 Mode LED1 Frequency Disable video processing Raw bits per pixel
Now you can run mjpg_streamer again and use pan/tilt!
