I’ve tried a number of things. Most recently have motion installed. All tools consistently get ‘cannot open /dev/video0’
I’ve tried 2 different RockPI4Bs with 2 different cameras
I’m running Debian Buster
uname -a
Linux rockpi4b 4.4.154-112-rockchip-gfdb18c8bab17 #1 SMP Thu Jan 21 04:50:13 UTC 2021 aarch64 GNU/Linux
cat /etc/issue
Debian GNU/Linux 10 \n \l
even
“ffplay /dev/video0” returns
“Not a video capture device. /dev/video0: No such device”
but when I: “ls -lsa /dev/video” I get:
0 crwxrwxrwx+ 1 root video 81, 0 Sep 13 20:54 /dev/video0
0 crwxrwxrwx+ 1 root video 81, 1 Sep 13 20:54 /dev/video1
0 crwxrwxrwx+ 1 root video 81, 2 Sep 13 20:54 /dev/video2
0 crwxrwxrwx+ 1 root video 81, 3 Sep 13 20:54 /dev/video3
any ideas what I might have wrong?
