USB camera with rapberryPi

[OMEN44]

Question

I've been trying some different setups with MediaMTX on my raspberry pi and found that by far source: rpiCamera provides the lowest latency when I use the webRTC iframe in a browser.

I wanted to see if there was any way that I could use this with a usb web cam for example I have this one?

set 15 fps with and height always before

v4l2-ctl -d /dev/video0 -p 15 --set-fmt-video=width=1280,height=720 --set-ctrl=brightness=57,contrast=-11,exposure_dynamic_framerate=0

in this examples audio device = plughw:0 this is the first audio device ! best streaming !! no audio video delay very stable
