Hi, USB camera is supported on ROCK Pi S. See this guide, https://wiki.radxa.com/RockpiS/Debian#Use%20USB%20Camera.

The problem is that the documentation says to upgrade the “kernel to version 4.4.143-41-rockchip or newer.” but when I run “sudo apt-get install -y linux-4.4-rockpis-latest” I get a reply that “linux-4.4-rockpis-latest is already the newest version (4.4.143-39-rockchip)”.
So I switched to the testing repository, upgraded, rebooted and it worked:

cat /etc/apt/sources.list.d/apt-radxa-com.list

# deb http://apt.radxa.com/buster-stable/ buster main
deb http://apt.radxa.com/buster-testing/ buster main

This was bugging me for a bit until I saw that it needed the latest kernel.

Yes, USB Camera support was newly added several days ago.

Is there a way to decode the USB camera with ffmpeg and hardware acceleration?
