20, 30% is not a lot, my other IP Camera (with jpeg stream) spend more then 25%..

I searched up and down in the web but I don't found anything about v4l2loopback.. maybe is EOF ?
Thank you!

this is from a pervious poster... works well, however CPU usuage is 
around 20-30%for each camera, it uses a video4linux loopback.

One working variant (I'm using it for more than 1 month without problems):

use v4l2loopback , to create /dev/video1.

then with follow cmd, feed it with content from you rtps net camera:

/usr/bin/gst-launch-0.10 rtspsrc 
location=rtsp://admin:admin@...> ! decodebin ! v4l2sink 
device=/dev/video1

(you need gst-plugins-bad, and gst-plugins-ffmpeg)

then describe /dev/video1 as videodevice in motion.conf, and restart
motion.
