Raspberry Pi USB Webcam Testing

This post will unfortunately be very short.  I was playing around with a webcam connected to a Raspberry Pi, and just as I was starting to make headway I got sick.  I was using a Logitech C525 to take still images.

I got far enough into the project to realize that the camera didn't have enough resolution for what I wanted to do.  So I need to look at other options.

Just to document what I've done I'll include the commands I was using here.  fswebcam was used to take the still images and uvcdynctrl is used to configure the camera, but it's poorly documented and I'm still trying to figure out how to use it.  You may need to install packages to use these commands.


fswebcam  -r 1920x1080 -s brightness=70% -s gain=50% -S 10 test.jpg
uvcdynctrl -L a.txt
uvcdynctrl -s "Focus (absolute)" 220


I promise I'll do better next week.
