Content-Type: text/plain; charset="utf-8"
With Motion 4.1.1, does the mmalcam option (I am using a PiCam) still work? I
was reading the Basic Setup page for Motion on the GitHub site
(motion-project.github.io) and it said for using Motion installed by apt to use
the bcm2835-v4l2 module (sudo modprobe bcm2835-v4l2). If I should be using the
module, is loading it a once and done thing or do I need to load it after each
restart of the Pi?
Thanks.
