Streaming problem

Marinator · Post by **Marinator** » Mon Aug 01, 2005 6:16 pm

Hello, I love Zoneminfder and it is working well, except for a small problem. It appears that some JPEG's my camera is sending are in an invalid structure. This is causing zmc to crash and restart constantly. The effect on this to me is that about 75% of my events contain about 40 JPEGs that are completely black and have no information in them, then the correct images begin when viewed in "still" mode. These events will not stream using JPEG or MPEG, but rather the first valid image only is displayed.

I am using a Toshiba IK-WB01A over 802.11b Wi-Fi. I can login to the camera's native interface and watch uninterrupted streaming with no apparent dropping of frames.

I am running it on a ClarkConnect box which is CentOS 4 which I think is pretty much the same as Redhat Enterprise Linux 4.

This is my zmdc.log:

There is the additional issue of the uninitialized value in zmdc.pl, but I don't really know what to do about that. Line 346 is:

if ( $pid_hash{$cpid} )

and appears to be in the restart subroutine so if I can get ZMC to stop crashing, it should go away.

This is my messages.log

I guess I am looking for a solution that may involve ignoring the error or fixing the JPEG before it gets analyzed or anything else that may work.

Thanks in advance.

Assuming you have 1.21.3 try modifying Options->Network->ZM_NETCAM_REGEXPS?

Thanks Phil, I have tried it and it seems to make no difference. I have also tried changing ZM_HTTP_VERSION to 1.0, also with no effect.

Any thoughts on how I can ignore the error to prevent zmc from crashing?

Thanks

Marin

Anyone have any thoughts?

I am running v1.21.3 and I have tried switching both ZM_NETCAM_REGEXPS and ZM_HTTP_VERSION but neither made any difference. This is a sample of my messages.log

Does anyone have the Toshiba IK - WB01A working properly?
