[Motion-user] RTSP stream and CPU utilization

[David P. <da...@de...>]

I have 3 IP cameras configured in Motion running on a Raspberry Pi 
(Ubuntu).  These cameras all use MJPEG streams and the CPU utilization 
on the Pi hovers around *50%*.

I added another camera which doesn't support MJPEG, but does support 
RTSP.  Adding this one RTSP camera ran the CPU utilization up to around 
*200%* (I believe this Pi has a quad-core CPU).  Is this typical for 
RTSP?  Is there any way to reduce the load for this protocol?  I want to 
add several more cameras but cheap wireless outdoor IP cameras that 
support MJPEG seem to be hard to come by nowadays.
