TimeLapse not functionning



I’m testing NetCam Studio to replace WebCam7.

As for now, everything seems to work, except TimeLapse…
I’ve setup TimeLapse functions as follows:
Frame interval (input): 1min
Frame interval (output): 1day
I’ve also setup the scheduler of my camera so that TimeLapse works all days long.

Problem: when the server starts, the timelapse starts, catches 1 picture, and after 1 minute, generates and 0-byte AVI file, and stops.

  1. I don’t want the TimeLapse to stop (and never restarts by itself) !
  2. Why is the AVI file always empty (null size) ?

I’ve made a test with v1.1.9, and then, with v1.2.0 b2, same behavior…
Strangely, TimeLapse stops after 1 minute, that’s to say at the time it should capture a new picture ?!?
Starting the TimeLapse manually (right click on the cam) does the same.

Can you help ?


Do you really want 1 frame to last 1 day in the output movie ??

This is probably why you have error. The 2nd parameter is frame duration meaning how long it will last for a single image in the output movie… You most likely want this < 10 seconds.

The timelapse shouldn’t stop by itself, ensure that you have no rule that trigs its stop and check in the logs if anything special or an error is reported there in case it stops prematurely.


No, indeed, 1 day was a mistake !
I’ve now set the output frame delay to 1 second…
I just want to capture 1 picture every 1 minute, but all day long.

But I’ve still got the problem with the TimeLapse !
I have no rule that could trigger starting or stopping of the TimeLapse.
Actually, I’m getting 1 (sometimes 2 or 3) pictures, and then, the TimeLapse is stopped.
When I only get 1 picture, the AVI file is 0 byte long.
When I get 3 pictures, the AVI file is correct.
I think the AVI file can only be generated once it has enough data (pictures) to merge, could that be right ?

Well, concerning the TimeLapse stopping, I don’t see why it acts that way.
I went into ServiceHost_20150619.log file to see if something could be found inside.
There are many lines:
Source(0).TimerInactivityElapsed Source(0) - Video Source Stopped due to inactivity.
I’ve got a desktop gadget that queries the cam every 10s (works well), and I’m getting a line like above every 10s !
It seems that the cam enters in sleep mode after a couple of second, and once it’s sleeping, the TimeLapse stops…

I made another test. I launched the NS server as an application (normally, it runs as a service).
As long as I stay on the “live view” tab (showing the cam), the TimeLapse seems to stay runnning.
But as soon as I switch to another tool (library, configuration or whatever), the TimeLapse stops and I get a message like above in the log.

However, I haven’t seen anywhere a parameter to tell the cam to enter in “inactivity mode” after some time !
(The cam is a Microsoft LifeCam connected to a USB port).

Any idea ?


Timelapse movie generation will fail if:

  • Not at least 3 images
  • Frame duration > 1 second (bug on our end)

Normally the timelapse feature being activated should prevent the camera from going to sleep, we’ll verify…


OK, frame duration = 1s, but there are usually only 1 or 2 frames captured, that’s why the video’s not generated…

But for sleep mode, for sure, both v1.1.9 AND v1.2.0 beta do enter it !
My cam IS entering in sleep mode after a couple of seconds (I can see it with the LED of the cam switching off).
And immediately after, the timelapse is stopping, and the AVI file is created (actually with a 0 byte length because there’s not at least 3 frames captured).


Confirmed, timelapse feature does not prevent camera from going to sleep. Will be fixed in next release…


Today, I installed your 1.2.0 RC1 version of NS.
This release should correct the sleeping mode of the timelapse feature.
But actually, it still doesn’t !

My webcam still enters in sleep mode after a couple of seconds, setting the timelapse to stop.
Here’s the log since installation (simply tested by starting the service, seeing the cam entering in sleep mode, and then stopping the service):

Can you have a look ?
