Cannot start usb_cam, libs newer available but an only version needed

edit

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/po...

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:
