Hmm, can you post a longer stretch of debug if you have it?

I think the HT is the beginning of 'HTTP/1.0 200 OK' which is the first line that should be sent.

This is the output I get from the camera I have found, firmware 2.31 again.

Perhaps there's some setting in the cam itself I've got wrong?

Can you do a wget -s on this url? It will probably sit there fetching, just let it go for a few seconds and kill it. If you just 'vi' the saved file and cut and paste the first few lines it might help. Here is mine.

Looks like it's sending things right but not being interpretted correctly..

-- Cy

I assume you had the first two lines as well? The HTTP line and first header? Also that you had the later of the teo versions of 1.19.1 (I don't think anyone downloaded the first one).

This is very odd, your stream looks the same as mine but your binary can't read it. I'll mail you the address of the other camera I found, I wonder if you could try that one and see if you get anything different.

Phil,

Odd.. still doesn't work.. I'm going to try recompiling from scratch, see if that helps.

-- Cy

Hrmm.. still no go I'm afraid

I've got the right tarball right?

# md5sum zm-1.19.1.tar.gz
95f471adea075ea12aa681730b771b37 zm-1.19.1.tar.gz

-- Cy

Yes, that's the right version. Did you try the URL I mailed you?

Phil,

Yeah I did, I get the same error "Unable to extract subheader from stream, retrying"

-- Cy

That's even interesting'er.

So my binary works with that URL and yours doesn't. That would seem to imply an issue with the build or perhaps more likely, the regular expression libraries. Which distro are you on?

Phil,

That's what I was thinking.. it wouldn't be the first time..

RedHat 9 presently

-- Cy

Ack, I'm on RH9 too. So what could be different?

Can you do a

<i>rpm -qa | grep pcre</i>

and list what comes out.

Phil,

pcre-3.9-10
pcre-devel-3.9-10

-- Cy

Same here. Oh well. I'm going to sleep on this. I'll try and get back with some other suggestions tomorrow. Maybe I'll send you a test program to try.

Phil,

Thanks again for all your help, I really do appreciate it.

In the meantime I'm going to see if I can't make it go on a couple random suse/debian/slack boxes I've got scattered about, I'll post any interesting results.
