Re: [Motion-user] timelapse

You could always just take a snapshot every 15 seconds. Write a script which loops forever to:

      /usr/bin/wget -nv -o $WGETLOG http://$HOST:8080/0/action/snapshot
     sleep 15

You'll need to adjust the wget options to your installation.

 Then point a browser at the picture and have it update every 5 seconds. You'll need to ensure that the pictures you take always have the same name (controlled via motion.conf).

I do something much like this - I have a web page which contains a link to one image from the last event from each camera. Every three hours I take one shapshot just to convince myself that the camera is still working.

Sorry about the top posting.

hey gudy -

wny not use the timelapse feature in motion?  that's exactly what it's
for.  you can set it to make an image every so many seconds.

John , i have been looking up the timelape option in the motion config  
guide, but correct me if i'm wrong,its only for making movies with ffmpeg.
What i have is 6 threat config files, 1 for each camera which are calling  
kmotion, to view the pictures on the screen and update when there is  
motion detected and motion puts a nice square on the detected area, so  
that i can see in one time what's going wrong

I produce plastic bags, I'm the only one to operate my machines. things as  
cripple are easy to detect,  but small changes in size you are always much  
too late to discover it: example size needed 35 cm, but 34 is wrong, and  
36 also. that's why the mask option in motion is very helpfull. But I  
can't to get this done with more then 1 webcam

So I don't need movies or to store thousands of pictures, simply to see  
the last motion detected picture of each webcam
if every cam will be updated in 20 sec (3 pic /min for each channel) wow  
then I'm very happy, then i can be busy with cutting bags while motion  
will keep an eye on the extruder, and i only need to go there when things  
are wrong ,without unnecessary running between machines



Have a nice day
