Single Black Frame

[palanski]

Hi,

For some reason, when I begin the capture process, the producer/consumer loop structure below gives me the first image as being black(empty) with all subsequent frames working fine. I'm not exactly sure why it is doing this. Any input would be greatly appreciated. The frame before the one below collects information about exposure/gain of the camera and how many frames are to be captured, so shouldn't really influence the capturing process.

Hi Konstantine,

The reason that you are getting this is an issue with dataflow, you are placing a element in the queue before the buffer image copy is complete. Try combine all the error wires in the top loop to enforce dataflow.

Such a simple thing. Thank you.
