Hi.

On Fedora Core 4, when trying to view a stream from a network camera, this what the log file shows:

On another PC, with Fedora Core 4, all works fine. Any idea about this one?

Thanks.

looks like the stream is getting corrupted. Maybe a bad nic card or something is differant about the network it on.
That would be my first guess.
What's differant between the two?

Hi Cordel.

Quite a lot . The working one has a better quality motherboard (Intel I think) while this one has a SIS chipset. The network cards are diffrent as well - both of them are integrated in the chipset, but Intel's one is much better. Both are in the same network.

I came across something last week about the sis chipsets that had me deside that I didn't want to get them any more. I don't remember if it was compatiblity with linux or hardware but I do recall that it had something to do with networking and maybe the way it handles the pci bus.
I'd give ya the link if I could remember what it was.
Have you tried adding the sis drivers? : http://www.sis.com/download/

By the way nice to see ya back around

Hi Cordel.

Thanks man - it's very nice to feel welcomed .

Phil - I think that this one goes to you - I ran the zmc with gdb, and discovered a pesky segfault:

Program received signal SIGSEGV, Segmentation fault.
0x08066c4e in RemoteCamera::GetResponse (this=0xeddc8b0)
at zm_remote_camera.cpp:820
820 subheaders[n_subheaders++] = subheader_ptr;

Looks like a memory leak? But wait - things are becoming even more stranger, when running the zmc with DBG_LEVEL set on 9, after a while the following segfault appears:

Program received signal SIGSEGV, Segmentation fault.
0x006804aa in vfprintf () from /lib/libc.so.6

Got my head scratching on it. BTW, all happes on FC4, with GCC4 (perhaps my previous post about GCC4 was a little too much optimisitic ).

I will have a look at this. I've just put FC4 on an old box I had in the corner so I have a cutting edge (though dead slow) box I can check these things. You could try using Regexps for remote cameras instead which might help.

Hi,

Another report from the land of FC4 + ZM adventures .

Sometimes the zmc allocates a shared memory, but then it can't connect to it. The ipcs command shows the allocated segements, but also that no one connected to it (0 nattch). The syslog shows the following message - can't shmget...probably not enough shared memory:Permission denied. The owner of these shmem segments is apache of course, but zmc still can't connect for some reason.

Just one simple question just to make sure it wasn't over looked.
Did you disable SELinux?

Hi Cordel.

Yes, I did.
