I am using a USB camera and uv4l to stream the video to another machine. This is how I invoke uv4l:
uv4l --driver uvc --device-id [bus:id] --config-file /etc/uv4l/uv4l-uvc.conf
I want to configure the camera exposure, resolution, brightness, etc. but I can't find a way to do it. Before installing uv4l I can use
uvcdynctrl to set the parameters. Now
uvcdynctrl both say that they can't find any devices. I'm using a Rpi 3 and Raspbian Stretch. Please help. Thank you.
