error 74 (Unflatten From String )

[DOHAAACB19619]

I want to capture a video using labview 2015 and then sending to labview communication using UDP, using the OFDM example implemented on labview comm(TX,Rx) after this process we then send the video back to the normal labview 2015 using again the UDP,  the problem is that when we run the two programs there is an error 74 (Unflatten From String ),and there is another something occur that the output display that receive the video it give an output only when we press right click on the display indicator otherwise there is no output,so i want to know the meaning of this problem. there are two attachments(screenshot for the code implemented in labview 2015 ) which show you the the capturing of the video and receiving it from labview comm.

any one can suggest a solutions for these problems.

thanks a lot,

It looks like you're also getting error -1074396120 "Not an image" out of the IMAQ Flatten to String VI. It's possible that error 74 returned by Unflatten From String is a result of attempting to flatten and broadcast an invalid image. This might also explain the behavior you're seeing displaying the image.

It might be worthwhile to try running a simple VI that only acquires an image from your camera without any of the additional UDP code. This would verify that there is nothing wrong with the acquisition itself.

thanks a lot for your help;

already i tried running a simple VI that only acquires an image from my laptop camera without any of the additional UDP code,and I found it working well.

I will tell you an overview about my project:as long as there is no vision acquisition in labview communication so the only use for the  labview 2015 is to acquire the video and then sending it to the labview comm using the UDP,and I need also to receive the video again in labview 2015,but the main code for the project is implemented in labview comm as i want to use the OFDM technique for transmitting and receiving the video, so I try to use the OFDM example implemented in labview comm, so i think the main problem is occurred when the video introduced in labview comm.

 so i will send you an image of the code of the project implemented on labview comm,

the first attachment is the UDP receiver that receive the video from the labview 2015, the second attachment is the OFDM (TX,Rx),the third attachment is the sender UDP that it is supposed to send the video back to the labview 2015. 

can you help me finding the problem that cause this error.

I am so sorry for wasting your time, and I am grateful for your help

The error looks like it is because a purple image reference is being flattened, but what is being unflattened is a cluster of an image reference.
