I have been trying to stream my webcam over http with a raspberry pi 2 using mjpg-streamer. It works to stream the webcam and also some of the image controls, like brightness, focus, etc...
What I cannot seem to get to work is the zoom controls on the logitech's QuickCam Pro 9000. On a windows PC with the logitech software, I am able to zoom in and out. Yet, using mjpg-streamer, I am unable to replicate this control.
I have looked at a lot of links such as: http://www.slblabs.com/2012/09/26/rpi-webcam-stream. (Note: I cannot post more right now as I do not have a high enough rep. See more links in the question that I asked here)
Yet, I have not been able to figure out the zoom control for the webcam. Anyone have any idea how to get the zoom controls working with mjpg-streamer or another video streamer for USB webcam for the raspberry pi?
Note: I asked this question here as well, and they said I may be able to get an answer if I posted it here.
