usb_cam pkg gives garbled green screen

asked 2019-06-12 16:00:19 -0500

I have a ROS kinetic on my virtualbox. I tried to use "usb_cam" pkg but it doesn't work. My web cam is connected directly to my PC and I can see the video through "cheese" or "camorama" but when I run usb_cam pkg, I get garbled green screen both on "image_view" or directly on "rviz" for image_raw. I tried both yuyv and jpeg for pixel format but it doesn't work. Any suggestions ?
