I just can't figure out how to set the parameter I need in order to rotate my camera 180 degrees (I have my webcam mounted upside down for a custom mount I made).
I'm using a Logitech C270. I've been searching online for hours for a solution to this issue and just can't find what I'm looking for. Doesn't help that I'm not very proficient when it comes to this stuff.
If I run the command suggested in GiF's answer:
mjpg_streamer -i 'input_uvc.so -rot 180'
I get the following error:
libv4l2: error setting pixformat: Device or resource busy Unable to set format: 1196444237 res: 640x480 Init v4L2 failed !! exit fatal i: init_VideoIn failed
I seem to get that error when setting any parameters. I'm running Octoprint, if that makes any difference. There doesn't seem to be a rotate option in Octoprint.
Information just seems extremely sparse on this particular fork of mjpg-streamer. Searching for that error just gets me a bunch of people that have non-working webcams while mine works perfectly, I just need to rotate it 180 degrees.
I would really appreciate some help!
