BT848, Ok on xawtv bıt zm not

screamuser · Post by **screamuser** » Sun Apr 04, 2004 4:18 pm

With a bt848 tc card, I use composite web-cam. On xawtv in linux it works perfectly even then windows. But in zm web pages every thinks are seem to be okay, and when I press to monitor my the cam (video0 composite 1 and pal mode), on stream mode, a blank page and 0 frame captured, still mode no picture AND AGAIN 0 FRAME CAPTURED. What is the problem, zm no captured even one frame, because images directory empty. What must I do?

Thank you

Screamuser,
Have you checked your logs to see what if any errors are being loged?
If you used the defualts the log files for zm will be in your /tmp directory.
I'd look at the zmdc.log and zmwatch.log for starters. Post what errors you find. That would help us to help you.
Thanks,
Cordel

Hi,

I am havint exactly this same problem. Xawtv works fine, but zm doesn't.
I am using a Fedora Core 1 distribution, with MySQL 3.23.58 and ZM 1.19.1, on a Celeron 2 GHz Machine with 512 MB RAM. I have a BT878 video capture card connected to an analog camera, with NTSC format.

Upon reading the "Troubleshoting" section in the docs, I found something related to "Shared Memory", I think (maybe) this is what causes the problem, but so far I have been unable to solve it. I also tried installing ZM on a laptop with a webcam, and found the same problem. So, maybe it is something I am doing wrong?

-----
On the machine described above (not the laptop), the output from /tmp/zmdc.log is as follows:

Any help would be appreciated!!!

Hi Marco,

I think your main problem is the 'failed to set window attributes error', look here for a way to address that.

Phil,

Can't locate MIME/Entity.pm in @INC

You need a perl module called MIME::Entity

It think a

Code: Select all

cpan MIME::Tools

should install all the needed code!

Be aware, that your access rights to the grabbed image are right. if you test the zmc-script manually on the commandline, the grabbed image would have wrong rights, so the zmc-process running under the web-user can not overwrite it anymore!

hope this help,
Malvo

Great! It's working now!

All I had to do was download the perl "module" with cpan, as told in the previous message.

By the way, I also tried with version 1.19.2 and had the same problem, which was corrected in the same way as with version 1.19.1. I don't know if this issue is too obvious, but maybe it should be included in the troubleshooting section of the docs that come with the package.

This goes to prove that you can do a "Fedora 1 Core - full install" and still be missing stuff

But I guess that's normal.

Thanks for the help.

Marco.
