Hi
I would like here to report on the problem of video freeze after some time.
This problem has been already discussed in different topics, but I think it is worth starting a new one, as -at least on my machine- the problem remains unsolved.
The latest driver CL-Eye-Driver-4.0.1.0501 and the latest SDK CL-Eye-Platform-SDK-1.1.0.0509 explicitly addressed this image freezing issue and some users already reported that these releases solved their problems, but I experience the same freezing problems on my machine, and the new software did not help.
This problem affects both standard applications that come with the driver and my own applications written with the SDK. In my examples, I will report on the standard applications, but fixes to the SDK should also be considered.
Short description of the problem:
1. Uninstall any previous driver and SDK
2. Install the driver CL-Eye-Driver-4.0.1.0501
3. Start the application C:\Program Files (x86)\Code Laboratories\CL-Eye Driver\CL-EyeTest.exe
4. Wait
After some time (depending on the camera, see hereunder), the image freezes. The camera cannot be used anymore until it is unplugged and re-plugged again.
I’ve been testing with different cameras, and the strange thing is that each camera has its own, quite predictable “grace period” time before it freezes. For the “worst” camera (in that sense), the image always freezes in a maximum of 3 minutes. Other cameras can work for 20 minutes, but still freeze after some time.
I’ve read in other threads that the camera should not be plugged in a USB hub. I therefore tried all the USB slots of the machine, inclusive the ones directly connected to the mother board, and the video always freezes.
Here are the specs of my machine:
Windows 7 - 64 bits
Intel Xeon CPU W3520 @ 2.67 Ghz (4 cores, 8 threads)
24 GB RAM
I know this problem is difficult to track down, as it cannot be easily reproduced, but I’m happy to help testing different things on my machine. What we (beta-users) could need is a debug driver that logs the state of the camera in a file. I think this could help to find out what causes the problem.
Thanks for looking at that problem
