I'm not having any issues with my webcam, quite the opposite. It works perfectly (Logitech C270).
I do, however, have other raspberry pi machines dotted about my house (dating back to the original V1!), that have webcams plugged into them, running "motion" and then streamed so I can keep an eye on things when I'm not at home.
The thing is, that the software,"motion" only streams one frame per second, no matter what I put in the config file...and yet, the software that's streaming over "webcam/?action=stream" through octopi is closer to 10-15 FPS.
How can I use the same software to stream my other cameras at the same rate?
I hope this is allowed to be asked here. If not, then please delete.
