If you don't find a solution, maybe you can use a USB sniffer program to compare what happens in Skype to what happens with your LabVIEW interface. I haven't done much with USB in LabVIEW, but you might be able to duplicate a working protocol interface with RAW mode. I would only recommend this as a last resort... painful...
Hopefully some of the LabVIEW USB gurus out there will chime in...
Here you need.
1. Program can take picture from two webcams ( One Vimicro _ZS0211, One Del on Laptop). It's picture below
It's source code is attacted with name 2 Webcam
Second, you can Use Library for Webcam USB (Attached file) and you can get image from Vimicro webcam. Below is result
You can download this library and it's example program from attacted file.
Third method, use NI Vission assistant (Sorry I can not send to you this code because I just use evaluation version_can not export to LabVIEW Code)
If you still can not pass your problem, please send me:
Your code for webcam, I can test it with my Vimicro webcam.
You can send me picture about MAX appearance (I want to know your driver and soft you already installed on your labtop for NI vision)
...I doubt that, maybe your trouble come from driver you installed on your labtop.
Where did you download driver for webcam Vimicro?
And... I send to you one small software, you can use it to download any kind of Vimicro Webcam USB
Hi ino measure,
I used the method 2 you are suggesting.
I have the following error shown in figure attached.
It says its having hard time finding library function associated with it.
I already installed the software drivers (in CD) that came with the camera.
Any help will be highly appreciated.
PS: Im using labview 2009 on windows 7 64 bit
i'm trying to use your Library for usb cameras but I get the the following errors:
"Library not found or failed to load" error when trying to run the program. The details for all errors reads "The library specified for this node cannot be found or cannot be loaded. Right-click the Call Library Function node and select Configure, then choose the correct library name or path."
So I right click on the function and click on configure, then search for the specific library where that function comes from, and assign the function call to that library, I get the following error: "The library selected is not valid for the current platform. For example, you are running 64-bit LabVIEW and the library might be a 32-bit library."
Is there any way to have a 64-bit library for Webcam Interface?
many thanks in advance,
Use IMAQ cast image
