That's great because I didn't see anything wrong with the code. I guess the source of your problems was in the AVI file itself.

wwwoooooooowwwwwwwww........
I have found the solution. I have downloaded a software called "VirtualDub" and convert the video to "segmented avi" and it works with my VI...
Thank youuu alllll for the help. If their's any suggestions to ameliorate my program I wil be so glad to hear from youuu..

Thank you Bruce,
The first one is the main VI and the second one is the subVI that I have generate with Vision Assistant.

Hey every one,
I have tryed with GSpot but it doesn't work. I mean that my program display an "Error -1074396120 occurred at IMAQ Extract Single Color Plane
Not an image" when I used the full video, but the program works with part of this video that I have extracted with Ulead Video Studio.
I have looked for this error in NI forums, but no solution has solved it. even I used "IMAQ create" as it was said.
I couldn't attach the videos while they were too long.
Here an attachement of my program which consists on doing an OCR on .avi video. To mention i used vision assistant to generate the labVIEW VI, I attached the script
that I have made as sub VI. Have any one any idea what's all about?
Thank you very much.

Thank you Bruce,
I used my computer for saving all avi that I have tryed, in fact I used Ulead Video Studio for converting those vides to avi format, so it uses the same
compressor(I think called PCM). Have you any idea what sall I do?
Thank you

Hey everyone,
Can someone tell me why NI Vision assisstant doesn't accept all video (.avi) although they have same properties (RGB, 30fps) and same type(.avi). I am working on video
processing with LabVIEW8.6 but My program work on some AVI and doesn't accept others AVI.
Thank you in advance.

No, you get a handful of functions with the normal LabVIEW install, but the video and OCR functions are in a toolkit called the NI Vision Development Module. Come to think of it, maybe you don't need LabVIEW at all - have you considered NI's Vision Builder AI? It's a more interactive environment that doesn't require LabVIEW programming...
I've installed NI Vision Developpement Module and I'm working on it. Thank you very much

You'll need to install the OCR toolkit component if you want to use OCR (last I checked it was included in IMAQ Vision?), then you'll need to extract frames (images) that you want (every 1s) out of the video and do the OCR on them individually.
Thank you very much crelf. But my problem is how to extract every 1s a frame from the video? Is their a function that let me doing that? To mention, I think have already setup IMAQ Vision, isn't it with LabVIEW toolkit?

Hello every one,
Please can any one help me in programming my application. I'm trying to make number recognition from digital displayer. i found tutorials about OCR for still images. but my problem is that I have a 20 mn video as duration and i want to take the values from the displayer every 1s and plot them. But I couldn't do that because I know such task for just one frame. my webcom has a rate of 30 f/s.
i already setup labVIEW8.6 and Vision toolkit. but not IMAQ Vision OCR.
To metion that i'm just beginning to learn LabVIEW.
Thank you very much in advance for your help.
