Shared memory not initialised by capture daemon

[ClarenceDonath]

I've been trying for days now to make ZM work on my system.

First, the necessary information...

0) Check the Troubleshooting section of the README, look here if you don't have it handy.

Done.

1) Check the FAQ to see if it addresses your issue

Done. Not fully addressed.

2) Use the forum search to check whether your problem has been reported before

Done.

3) Check your log files, e.g. /var/log/messages, /tmp/zm*.log (or wherever you have defined your log directory)

This information follows.

4) Include the version of ZoneMinder you are running.

1.21.4

5) Include the type and version of your distribution

SUSE LINUX 10.0 (i586)
VERSION = 10.0

6) Include a screenshot of the error if it is in the web gui

The error is in /var/log/messages

7) Think about what other information you could provide which might be useful

OK

I am using an ibmcam, via the ibmcam kernel module, and this device works fine with xawtv.


Here is what I get when I 'zm start'...

I read in the forum that "ERR [Failed to set window attributes: Invalid argument]" can be harmless. This camera takes an integer value (0 - 6) to set the video size. Perhaps that's all that's being complained about here.


When I go to view the Monitor, I get a broken image, and when hitting the URL directly (http://spock/cgi-bin/cam/zms?mode=jpeg& ... 0&maxfps=5) I get from Apache "Server Error The server encountered an internal error and was unable to complete your request.
Error message: Premature end of script headers: zms"

And in /var/log/messages...

Please, what else can I do?

Correct, that this relates to the image size, but if a size or pallete is chosen that the camera don't support, zmc will choke and not be able to capture an image.

And in /var/log/messages...

Try just a standard size like 320x240. I assume it's a color cam so try RGB first and rotate though the pallet options till you find what works. You must restart zm each time you make changes to the camera settings.

You can also do
zmu -q -d0 -v
To query the cam to see what it returns.

Thank you for the reply Cordel.

Unfortunately, trying all the video sizes the camera supports (including 320x240) and cycling through all the palletes, the same behavior is still exhibited, "Shared memory not initialised by capture daemon" and a broken image. I made sure to restart zm for each iteration this time.

Interestingly, running 'zmu -q -d0 -v' produces the following for me:
root@spock:~->zmu -q -d0 -v
Error, failed to open video device 0: No such file or directory

I noticed this as well when running 'zmu' as described in the Troubleshooting section.

However, running 'zmu -q -d /dev/video0 -v' works, and returns the following:

Any more suggestions please?

[jameswilson]

im assuming you have tried 352x240?

[ClarenceDonath]

Yes, thank you

[jameswilson]

well looking at your previous post it appears the cam is ok and working, and you have tried the correct res and colour pallattes i really dont know. You say it works correctly in xawtv? What does xawtv report as the settings used

Well, xawtv comes up with the image set to default settings. The only information I can see that xawtv provides is with the -hwscan option, which returns:

/dev/video0: OK [ -device /dev/video0 ]
type : v4l
name : IBM USB Camera
flags: capture

[cordel]

And are you using chanel 0 and set for PAL?

I'm also having this issue. my specs are:

SuSE 10
ffmpeg 0.4.8
zm 1.21.4
apache 2.0.54
php 4.4.0
mysql 5.0.17

the message log that I get is:

My cameras are (1) Logitech Quickcam Web, and (2) Micro Innovations IC50C. I have installed both kernel mode drivers, and they both work on xawtv. I had the logitech working for a while, and then I started to get this error message.

I have them both set for 320x240 capture, and ntsc encoding.

[cordel]

Unless your unpluging the camera, It looks like it might be droping out according to your logs. If you have an extended cable it may be too long.

[winblowzxp]

That was me unplugging the cameras

My camera works just fine using xawtv
