Do you use rtsp stream?
I do and have much bigger horizontal move of pictures. I use dual core
Orange Pi with Gb Ethernet. I read that decoding rtsp stream needs lot of
CPU power (than mjpeg) so I believe it can be related to CPU power.
Best regards

That's a bear of a command line (which got me headed in the right
direction to make this work for my camera):
/usr/bin/vlc -I dummy -vvv v4l2:///dev/video0 --sout
'#transcode{vcodec=MJPG,vb=400,scale=1,width=640,height=480}:standard{access=http,mux=mpjpeg,dst=0.0.0.0:8080}'
--sout-http-mime="multipart/x-mixed-replace;boundary=7b3cc56e5f51db803f790dad720ed50a"
Unfortunately, VLC took 40% of my CPU to encode/stream this, while
motion is taking only 10-12%! (Go motion!) Plus, motion is already set
up in a nice service I can auto start/stop/restart, and I'd have to set
the same thing up for the VLC command above... but mostly, more CPU time
is bad....

Thank you! I had disabled the HTTP remote control because I didn't
think I needed it, but that is exactly what I was looking for (actually,
I'd like a startWithDetectionPaused ON config file option, but this and
a crontab is close enough).
Unfortunately, it appears that the actual detection of motion is about
1% of the CPU usage, and the encoding to a mjpg stream is the other 10%
of CPU usage, so it turns out it's not really worth disabling.

The problem is that my camera does NOT support hardware mjpeg output,
but I am now considering just throwing money at the problem and
purchasing a better camera that does to offload the CPU hit.
Or maybe I'll just accept the 10% continuous CPU usage and move on....as
I said above, it doesn't look like the motion detection routines are
adding significantly to the overhead.
Thanks,
Jay

Dear Motion users, maybe some of you could help me with udev.
My udev infor for video0 and video1:
http://pastebin.com/3KkXCwiG
http://pastebin.com/76dS2qAm
Then I set here:
nano ls /etc/udev/rules.d/usb-cam.rules
http://pastebin.com/CA8wkqAT
After rules reload:
udevadm control --reload-rules
I can see only webcam0:
root@LT310:~# ls /dev/web*
/dev/webcam0
Any ideas how to force udev working with both of video0 and video1 cameras?
Thank you and best regards
Mariusz

Use udevadm to test your rule

I believe this may be related to a bug with threaded config. At least those
stripes look familiar to me:
http://www.lavrsen.dk/foswiki/bin/view/Motion/SupportQuestion2012x02x27x155712
I can only suggest you to update motion to the latest trunk from github and
reproduce again
If it is still reproducible, file a bug on github, attach your config and
full log
