Camera not sending images for 7 seconds when enabled

[Spencer Logan]

Hello from team 1551. This year we are trying to do some simple vision stuff in autonomous to search for the hot goal. All we want to do is search for a hot goal, and then shoot the ball accordingly, so we hope to only have to run the loop once and not have to deal with a second image processor or anything like that. We are using the Wind River VisionSample2014 example because we are inexperienced with vision and a fairly small team. The only changes we have made to the example code is threshold values adjusted for our camera, and uncommenting the lines that save images to the cRIO. When we run the program, it spits out an error for around 5-7 seconds, and then runs normally. We assume the error is occurring because the camera is not outputting an image, because after the error stops, we can detect hot goals, and use the information to our advantage. We can always see the camera's output in the driver station and in the browser, and only the code is incapable of reading the image for those few seconds. For testing purposes we set the code to stop until it gets an image, just to confirm that there is nothing running in the code that would cause the change, but the error still occurs.

Just for reference, here is the error that is popping up.

Thanks for any help you can offer
