How to intergrate other part of application into the vi.

[ibuddler2005]

Hi,

I have an application (exe file I have no idea of its language) which can produce images at a video rate in the real time. Is there a way or possible that i can use the video in my vi application?

To explain better, a program will play a video and at the same time I want to use that video in my vi.

Thanks in advance.

Do you just want to view the video? Or do you want to do stuff with the video?
If you just want to view it, you can use an ActiveX control to view it through something like WMP.

here is an example of what cory was talking about:

Hi, thanks for your reply.

Umm... The video is not a "video file" actually. The application will produce and display the video on screen but not record to a video file. I'm not sure if the activex can do that. 

Anyway, if so, what's the difference if I want to process the video? My vi will do something (e.g. ROIs, TTL trigger) to the video. How can I call WMP to display the video? (The video is a part of that application).

Thanks.

For LabVIEW to be able to process/analyze the video in any way, it has to be able to access the data somehow.

Is there a file being written anywhere? Even if it is only temporary?

Otherwise, all you can really do is just call the program through LabVIEW, but you cant do much with the aquired data.

Thx. The application can write the video to an avi file. But can labview access a file which is being written by other application?

hi ,

 am also having a pbm similar to this. Using my prg I can captuer still images. But in my task for each wavelength I will have to focus and capture the image which would be better with a video image. I have added grab/capture images from the vision.But facing the pbm

1) am not able to identify the interfacing name 

2) anyway it is not showing image in the video image screen.

Please continue in your original thread where over 30 messages have already been posted in trying to help you.

It is also helpful that when you type a message, you use complete words and not use "text messaging speak".  Are you sure you have the drivers installed for the camera?  All you are showing right now is an ordinary com port.

Right now ,am using the software (not labview) provided by the camera and the filter to capture images and process it .it is working properly and giving good results.But  our aim is to control the whole processes using a single labview program.

I followed this thread because, I found similarity between this problem with mine. Also instead of YOU if we type U, it is understood what does it mean. We are not writing any spelling test. Our idea is to convey our problems and opinions.
