BUG: Multible Netcams doesnt work longer

When i run Motion with 2 NetCams, one Cam ist stopping after a short time. My NetCam from Thread1 is a D-Link dcs-900, the Cam for Thread2 is an Axis 205. Both Netcams are connected cia an Ethernetswitch to the DMZ from the Server. The DMZ is a 100 MBit Ethernetinterface only for the NetCams. After starting Motion, one the Cam from Thread1 ist working fine, on next Startup Motion perhaps the Cam from Thread3 working fine.

The motion.conf is the original from motion-dist.conf (only my path ist changed) und my thread config Files comming here:

both Threads alone working fine (but the Message "Thread Condiction timeout" comes also)

Test case

Environment

Motion version:	3.1.19 Snap1 with latest patches from Angel
ffmpeg version:	0.4.8
Shared libraries:	curl, ffmpeg, mysql
Server OS:	SuSE Linux 9.2, kernel 2.6.8-24.11

-- EmptySoft - 12 Feb 2005

Follow up

First curl are not needed from motion-3.1.18 because the new netcam driver make the use of it obsolete. What's the framerate did you setup for each thread ?

Thread Condiction timeout message is because the thread that gets image from net spend more that 5 seconds to get a non error image. I'll gonna add the thread information to this message to allow users to know which thread is making errors.

Take the patch from http://www.lavrsen.dk/twiki/bin/view/Motion/StreamingNetcamWithoutCurl , and try to run motion in no deamon mode to get detailed information. Try to report the log when one of the camera fails.

My Framerate is set to 2. Your Netcampatch is already installed. The output from Motion say nothing from stopping capture images. There is only a "Closing devices ..." after save a snapshot.

Thread Condiction timeout

Most times the non working Thread only captures frames, but stopping bevor 1 snapshot. I have sniffed on the Ethernet mith ethereal, there are no request to the sencond Netcam, but there are no Errormessages from motion output or the /var/log/messages File.

Now i have changed the axis from jpg to mjpg Stream. At this time both Cam´s working since a hour und it looks good. Not every Snapshot are saved (configured to 61 Seconds) but 1 in 5 Minutes are saved. There is always the Thread Condiction timeout from the motion output.

Are you sure that you have installed the new netcam patch ? , it shows thread number in Thread Condiction timeout , for instance Thread 2 Condiction timeout .

So please , be sure you have motion-3.1.19_snap1 with netcam-patch installed.

Snapshots for Cam3 looks OK File of type 2 saved to: /EmptySoft/WebCam/Cam3/lastsnap.jpg

for Cam1 only every 5. is OK (some times the 4. and then the 6.)

If i configured Motion to use jpeg for the Axis Cam (Cam3) then i get the diction timeout for both threads.

Du you have any Idea, what i can do for Condiction timeout ?

Note: I replaced your many <BR> by surrounding text by <VERBATIM> and </VERBATIM>

Can you confirm if the problem is still there with Motion 3.1.19 released?

-- KennethLavrsen - 03 Mar 2005

---

This still exists in Motion 3.1.19. I've attached a small patch that I believe fixes the problem.

-- ChristopherPrice - 18 Mar 2005

This should now be resolved for the D-Link DCS-900 and Axis 205 netcams in 3.1.20-snap5 and 3.2.1-snap12.
