Hi,

I want to stream the image captured by my logitech c200 webcam with rqt_image_view. I'm running ROS Kinetic on Ubuntu 16 in a VM VirtualBox.

The camera is connected to a RaspberryPi via USB. I launch a package which publishes the video stream. Everything works fine except for there's a delay in the stream of approx. 5 seconds.

When i connect the cam directly to my laptop, cheese, guvcview and rqt_image_view can not stream the camera. However in my Win10 host system the camera can be streamed fine without a delay...

Any tips on how to fix the delay?
