Hi All,
I'm interested in using my old smartphone camera with Motion, since it already
has a decent camera and wifi. Is this possible and if so, is there a guide/doc
that discusses how to setup for a Samsung GS2?
Thanks.

Hello,
is it possible to recive a rtsp stream from motion or can cvlc convert the
http mjpeg stream to rtsp on the fly?
I use the motion mmal version on the raspberry.
regards
Thomas

I've got a Galaxy S2-Mini phone set up with motion.
The phone has the Cyanogen Mod version 10 (akin to Jellybean) and I'm
running "IP Webcam" on it. This provides a nice MJPEG stream, that Motion
can easily handle and process.
I've had this working reasonably well for the past few months. As long as
I've manually set the IP address on the phone, I've had no real issues.

Hi Cathal,
That's great!! I'd love to get my old GS2 to work with Motion. Did a little bit
of digging after initial email and found an IP Webcam app on the android store.
I think I'll install this after getting the phone's power issue resolved and
give it a try.?
As for manually setting the IP address on the phone, perhaps assign a reserved
IP address for the phone's wifi MAC. The phone should always get the same IP
address from wifi router.
Thanks and have a great weekend.

Motion can't stream rtsp, only MJPEG.
You can use cvlc or gstreamer to re-stream motion's mjpeg. Just specify
http://localhost:8080/ as source
For example, I used this --sout to stream webcam:
--sout
'#transcode{vcodec=h264,width=640,height=480,fps=10,vb=500,venc=x264{preset=ultrafast}}:rtp{sdp=
rtsp://:1554/}'

Greetings,i am a newbie and learning linux(raspberry) user
i already got motion running in raspberry,i am planning to create simple
paper for my school project
but i dont get the explanation of Motion algorithm
from http://www.lavrsen.dk/foswiki/bin/view/Motion/MotionTechnology :
*Motion detects motion by comparing the intensity of pixels in a fresh
grabbed image with a reference image. Color information is not utilized. If
there is no motion and no noise new_image-ref_image should be zero. If
there has been a change in the picture the result will be different. To
prevent noise being seen as motion the change has to exceed a threshold and
there have to be a certain number of changed pixels before a motion is
declared.*
*The reference frame itself is recursively updated with the new picture, so
after it has been updated with pictureN it will consist out of:
1/2*pictureN + 1/4*pictureN-1 + 1/8*pictureN-2 and so on.*
can you explain in more detail? and what kind of paper or book you
recommend to study about it ?
and about the formula,does
*1/2*pictureN *mean :
a.half times pictureN
or
b. one divide ( 2 times pictureN )
thank you
