I have now tried nph-zms with and without REGEXPS
and the result is the same.

Can you do a wget -s -S on your full GetData url and then post the first few lines here. It's possible it's doing something ZM is not expecting.

Just a little more? I'm interested in what the first few bytes of the image look like.

Thanks. At first glance I can't see the bytes it's complaining about in this dump/ Do you always get the same error from the grab?

Also if it's publically accessible feel free to PM me access details and I'll try and debug it from here.

Do you need access to the web cam, or the ZM web page or both?

Post by **cordel** » Fri Oct 14, 2005 3:37 am

Phil would just need access to the camera.

I seem to be able to get a consistent image if I switch on Options->Network->ZM_NETCAM_REGEXPS however I am still trying to work out why the other method fails. I think most cameras normally prepend a crlf to the content boundary but this one doesn't so that might have something to do with it perhaps.

Phil

I have Options->Network-> ZM_NETCAM_REGEXPS checked.

Here is the system log when I change form /Jpeg/CamImg.jpg
to /GetData.cgi and back.

Can you tell me other configuration items to check?

Post by **zoneminder** » Sat Oct 15, 2005 5:59 pm

I got the invalid jpeg header when regexps weren't being used but not since. One thing to make sure is that you have compiled ZM with the regexp libraries, otherwise it probably won't make any difference (this probably should result in an error). Check what HAVE_LIBPCRE is set to in config.h in your ZM build directory (assuming you aren't using one of the distro versions).

Ok. libpcre did the trick. /GetData.cgi now works.
I'm still only seeing 5fps, I guess thats the best
I can get on a wirelss interface, maybe?
