I'm sorry to create a help request for a topic that's so often revisited, but I've been looking through the forums trying to find a way of adjusting a live mjpegstreamer stream from OctoPi when using an RPi camera all day, and so far nothing I have tried has worked:
control.htm - This won't and can't work according to this issue.
v4l2-ctl - Seems to accept commands, but doesn't seem to do anything at all to the stream. Stopping and restarting the stream also had no affect. I made sure to disconnect my usb webcam and reboot to make sure device selection wasn't a problem. Here is an example command I sent in case I'm doing something terribly wrong:
uvcdynctrl - I'm having trouble interpreting the output here, but following a few guides that were intended for use with usb webcams I wasn't able to change the raspberry pi cam image at all.
Can someone point me to a guide that shows how to change brightness, contract, etc. from a live mjpegstreamer stream for a pi cam using any method that works? Or am I on a wild goose chase?
