ZoneMinder Forums

I'm wondering if any one else out there is encountering these issues. I'm in the process of testing ne hd ip cameras for possible deployment in my home and several friends homes. I have the camera showing up in zonminder and I get some video, but the error log is huge I'm not sure what I need to do to fix it. Below are the errors I'm seeing. Zoneminder I'm running the latest version 1.27 is installed ubuntu 12.04, located in my esxi cluster. Below are the settings I'm using for my cameras. I would prefer to stay with mjpeg as I do us the motion detection built into zonminder. the camera is a Dahua, I'm trying to move from my out of date ccd Cameras to something that is a bit newer. any help is appreciated.

Did you install from source or use a deb? What is the make and model of the camera?

Hi,

Looks like your camera is using Chunked Encoding, which is a HTTP/1.1 feature that ZM's "Remote" source type does not support. If this is ZM v1.27 or newer, you can use the cURL source type, which does support chunked encoding.

It was installed via deb using the pa repository, the camera is a generic dahua 1080p ip dome camera.

I've tried cURL and it certainly helps but doesn't seem to fix the issue, I think the camera has the option of using http 1.0 I'll give that a shot to see if it fixes the issue.

Looks like cURL gives me the same error, Below is a copy of the log, unfortunately there is not way for me to change the http type on the camera. Any other ideas?

What have you set for fps? Does the errors keep coming if you set fps to 1?

The image decoder is complaining that the start of the file doesn't start with 0xffd8, which is how jpeg files should start, but instead with 0x7b22. 0x7b22 translates into the asci characters {". This may be the start of a json encoded text file, or something like that. Its not html, and not jpeg. Headers should be pruned off already, and I can't imagine that those characters are allowed as http header fields anyway. My best guess is that the html server is sending some sort of error in plain text, or that this is some part of the mjpeg stream you are trying to use. I don't remember if mjpeg streams have the 0xffd8 header stripped from the individual frames or not.

I see that you use an axis path to get the stream?
/axis-cgi/mjpg/video.cgi?date=1

That should either not work at all, or axis may have licensed their software to the producer of your camera. If it's the latter, then you may try the following path instead:
/jpg/image.jpg
It works well on my axis cameras.
