viso2 tf_tree problem

Hello to everybody. I want to use the mono odometer from vo for Odometry in the robot_localization. The first step which is allready not working is the vo. I always get the following error message: > [ WARN] [1455205411.959462457]: The tf from 'base_link' to 'camera' does not seem to be available, will assume it as identity! I allready looked for 2 days for a solution but i just found out that i have to use a static what i allready did. I use a static transform for the odom->base_link my launchfile looks linke this: > i need the tranform for moving the camera in the right direction. if i dont use the tf and the identity is used i can only use the VO with a pointing to the ceeling camera. maybe im missing something or not seeing something. thanks for any help.
