Subject: Re: [Motion-user] can Motion be run without using sudo
Message-ID: <[email protected]>
Content-Type: text/plain; charset="utf-8"
I checked lsmod and the bcm2835-v4l2 module is listed. However, it is not
listed in /etc/modules, so I don?t know how it is getting loaded on reboots. I
also had uncommented the line ?mmalcam_name vc.ril.camera? in motion.conf. I
have Motion 4.1.1 installed (installed by apt). I don?t know if that is doing
anything or not. I will have to do some more tinkering.
I am using ?v4l2_palette 17? Is that one okay to use with the PiCam or would a
different palette choice be better.
I appreciate everyone?s advice. I have been using Motion for a number of years
but as long as my Pi?s are running okay I leave them alone except for running
apt-get update and apt-get upgrade every couple weeks to keep them up to date.
The Pi I have been updating to Buster had been on Jessie and was running a 3.x
version of Motion. Lately, its networking functionality was not working
reliably on reboots.
