I launch roslaunch cam.launch and libavcodec version 56 and libswscale3 available but asks 54 and 2, which are not available. When sudo apt-get install ros-indigo-usb-cam quits because of broken references, so I installed using dpkg directly from: http://packages.ros.org/ros/ubuntu/pool/main/r/ros-indigo-usb-cam/ System is Raspbian Jessie Hypriot ARMv7 /opt/ros/indigo/lib/usb_cam/usb_cam_node: error while loading shared libraries: libavcodec.so.54: cannot open shared object file If dirty symbolic links are done to point the newer versions and fake version number: lrwxrwxrwx 1 root root 19 Feb 4 14:33 libswscale.so.2 -> libswscale.so.3.0.0 opt/ros/indigo/lib/usb_cam/usb_cam_node: /usr/lib/arm-linux-gnueabihf/libswscale.so.2: version `LIBSWSCALE_2' not found (required by /opt/ros/indigo/lib/libusb_cam.so) /opt/ros/indigo/lib/usb_cam/usb_cam_node: /usr/lib/arm-linux-gnueabihf/libavcodec.so.54: version `LIBAVCODEC_54' not found (required by /opt/ros/indigo/lib/libusb_cam.so)
