Sorry to dig this up again but I have noticed a strange behavior resulting in the same error messages when attempting to get live video. The errors were intermittent and I found that Apache 2.0.58 was the culprit. But I could only see this when accessing ZM from various remote clients and OS's ...

I dont know if this is the best thread for this issue .. advise me otherwise. There are definite bugs in motion detection that I'm seeing consistently on my AMD 32, gentoo system. I'll post error and log messages later on if I can isolate them. I think these may be related : 1) a randon monitor will ...

I'll leave these 'low level' questions for someone with knowledge of interrupts or DMA, or any code hackers: 1) Is it possible to block or limit other system interrupts during the time a video line transfer is occurring? (ie.. to ensure safe transfer of data. ) 2) Is it possible to optimize the DMA ...

Yes. on my intel + kodicom system I did that. Not only that I had to set the writing frame rates to different values - such as 7,8,9 10. What a hack! But it was the only way I could get rid of the lines. I figured it didnt matter anyway since a chip with even 2 shared video inputs were good for only ...

Is the picture also shifting left and right? If so I have the same problem.

I'm having the same problem. I didnt see it with 1.21 version ever so this is a new problem. In my case it is a single channel in usually the second input on a bt chip. Strange. and it always happens when I clear the old events. But here's the workaround ... Stop ZM. Use phpmyadmin and go to the ...

It's simple - dont use myisam, but instead use innodb. This can be done my modifyng the SQL database creation script with 'engine = INNODB'. you can search the mysql site for more info on this.

I found this to be a problem last year on systems with via chipsets and intel with 4 chip boards such as Kodicom 4400. http://www.zoneminder.com/forums/viewtopic.php?t=5978&highlight= http://www.zoneminder.com/forums/viewtopic.php?t=6165&highlight= As far I could guess it has to do with DMA and or ...

I am purchasing one to evaluate.

BTW.. Yes I tried varying just about everything ... -shared mem address, -Frame server, -net.core.wmem_max, -frame rate in zm -bios settings, -pnp settings, -gbuffer -kernel.shmmax -monitor resolution - (improves things but doesnt entirely solve. I prefer 640x480 anyway) -number of active monitors ...

Yes on my p4 Intel chipset system the problem largely dissappears, but not 100 percent. (see the link at the beginning of this thread.) On the EPIA it happens all the time - probably due to differences in the chipsets as well as a much less powerful machine. Less power means more time in the ...

Well things are really close so it seems that the VIA chipset is compatible especially with the results of v4lctl. However I'm now thinking the issue is within the bttv driver. In particular it may involve interrupts and loss of data with simultanous interrupts. My tests show prove that the more ...

Yes, The board is an m10000 using Via VT8235 and CLE 266 with Nehemiah 1G processor and 512M dram. I used v4lctl to see if each device was detected, configured and talking with V4L. So far everything looks just fine. Looking at error messages I just noticed I'm getting the message: [ZMU] ERR [Shared ...

This is similar to problems I was having previously on pentium system see http://www.zoneminder.com/forums/viewtopic.php?t=5978&hightlight= The artifacts occur anytime on record or live view using 640X480 mode and seen only with a moving object. I have only two monitors active and limit the image to ...

Hello, Try a few standard monitor resolutions. That is 640x480, 480x360, 320x240. Be sure to set all the monitor resolutions to the same resolution. Dont forget to restart zoneminder after making changes. Try varying the buffers say ... 20,5,10,10,1. Also check the shared memory max in sysctl.conf ...
