Hi there,

I've just update or security server frmo 0.9x to the latest 1.17.1 version but now I'm having some issues.

I'm using a IVC-120G 16 channel capture card, which had previously been working perfectly with the old version. Now with this new version the capture daemon seems to be not waiting for the capture card to select the appropriate channel before a capture is taken.

For example I have 10 cameras on channels 0-9. With the montage open I get a congaline of signals advance one maybe two channels up and down on the display. We as previously this was rock solid.

I really like the new version and it has a *lot* more polish! Well done!
But if you could help me find a solution to this problem that would be great!

Cheers,
Alan.

Hi all,

I've just rolled back v0.9.15 and now all is rock solid again.. So It looks to me like a new bug.. :)

Let me know if you need me to output logs/testing things..

Thanks,
Alan.

Hi Alan,

I'm not sure I exactly understand what the problem is. If you can send or post any relevant log output or screenshots it might be useful. More specifically I'm not sure what you mean by 'seems to be not waiting for the capture card ' and 'congaline of signals advance'.

Cheers,

Phil,

0.9.16 & RedHat 7.3 - compiled and work

1.7.0, 1.7.1 - not compiled:

zma.cpp: In function `void zm_die_handler (int)':
zma.cpp:29: `strsignal' undeclared (first use this function)
zma.cpp:29: (Each undeclared identifier is reported only once for each
function it appears in.)

Hi,

This is a new function call included in the last version. However a check for it should have been included and wasn't. I've done a fix for 1.17.2 but if you want in the meantime you can just comment out the contents of the *_handler functions apart from the exit line or apply the patches include below.

Hi Philip,

I've rolled back to the previous version as it's a production system we use. But I will attempt to better describe what was happening.

When I created more than one "Monitor" with the source settings like:

Video device : 0
Video channel : 0

and

Video device : 0
Video channel : 1

.. and you look at either monitor, sometimes momentarily you'd see a frame of some other channel (or the other channel eg 0-1 or 1-0).

When I add all ten monitor inputs to the system the problem would get worse. The channel swapping between monitors gets so aggressive they never appear to show their "correct" channel.

The really weird thing is that the frame "label" that is inserted into the image (eg "Backroom 27/01/04") stays correct in the image but is being shown on the wrong monitor.

I've tryed setting a Max FPS on all channels and turning on and off the ignore FPS option but it has little or no effect. To me it looks like either the card isn't changing channel fast enough for it to capture the right image or something else is getting screwy.

There are no logs that represent anything I can see as a cause, they look exactly like the older version when the system is running, it's just the output to the browser is all mixed up.

Hope this helps,
Alan.
