No output image or stream with Boson 640

[keerthana-kannan]

Hi, I am working with a Boson 640 and it is connected to an Intel NUC running ubuntu 18.04. I installed the ROS wrapper just as mentioned and followed all the steps. I am getting the following output after the roslaunch, it gets stuck there(please see the attached image). This is my first time working with ROS. Please help me out. I want to view the output/images as given in the examples.

Hello, could you check if the topic of the image is publishing something? with something like topic echo $topicname

@alezana Hi, I was able to use cv::imshow to stream the output but wasn't able to save the images using cv::imwrite. Is there any other way to store it? Thank you.
