Motion - Bug Report 2006x 09x 07x 113734

BUG: IS BugReport2006x03x10x000151 really fixed?

I've followed the recommendations of the Bug report and the fix, and my netcam capture is working much,much better (it can run for days), but still when it does fail on the "video grey", once that happens, it never hooks back up and I just keep getting grey images in my video.

I am running motion-20060807-051001. I'm capturing a JPG graphic from the NOAA web site for radar and satellite (so its not a true netcam per se) so I can create a daily movie each day.

Paste in your error messages, config settings, terminal window output etc in this text field.

Failed at last, took 6 days!!

Follow up

I have to wait for it to fail again, I'll post your doc when it does.

Fix record

I might additionally add that I run two instances of motion, one for my real webcam and one for this netcam. Would that have any bearing on this ? I used to run it all togther under one motion instance until this problem started happening.


Two things.

Did you try the just released 3.2.7?

Please run both cameras with ONE motion using two thread files.

2nd thing. Motion requires that dimensions of camera image must have both height and width that are a multiple of 16. Thís is normally not a problem. All standard sizes like 640, 480, 352, 320, 288, 240, ...etc are multiples of 16

The jpeg related software relies on this - it uses some 16 x 16 blocks.

There was a fix implemented so that Netcams can run none modulus 16 but I am not 100% all the code can cope 100%.

Do you run mjpeg or jpeg. If you can run mjpeg.

I cannot reproduce the error. I can disconnect my netcam again and again and it always comes back up.

-- KennethLavrsen - 20 Oct 2006


I download 3.2.7 and am running with that now, lets see what happens. Next I'll try running my usb cam and this netcam under one instance.

Follow up

I have my two Motion tasks running under one task. I have had additional failures under 3.27 - but they are very intermittent. Today I did a small test. My "netcam" is nothing more than a HTTP server on my local machine which posts a jpeg image I download at an interval from another web site, so its not a true camera in that sense. I stopped my web server and left it down for a while, and I saw the grey screen, but once I restarted it, the jpeg image came back as it should. I'm thinking that there must be some strange condition that motion does not handle quite right and that once it happens it cannot recover from it. I guess motion detects a netcam has gone down by "http page not found" ?


Teamloser - 10 Nov 2006


Please try to reproduce that problem with latest motion version 3.2.9

Thanks !

-- AngelCarpintero - 19 Nov 2007

Closed , it should work on 3.2.10 , reopen again if problem remains.

-- AngelCarpintero - 10 May 2008

I doubt the bug is fixed frown, sad smile , I'm using 3.2.11 on Centos 5.2 64 bit

I've a lot of threads and cameras. The problems only occur with 'still jpg' cameras, not mjpeg. I think problem worsens when there are a poor net link. I've seen motion adding grey images and then reconnect, but somethimes, it get stuck with grey image. The cameras are cheap from estcctv.com manufacturer, but they work well and not hang.

Please tell me if I can in any way.


This bug was related to 3.2.9 , many changes/ fixes since then , so please open a new bug report with detailed information , running motion with -d 9.
