I have a .bag file from a kinect which is writing the topics: camera/depth/image camera/rgb/camera_info camera/rgb/image_color/commpresed /clock /rosout /rosout_agg /tf I am trying to use openni nodelet to play it back ( I need to conect the data to another node) I am using: roslaunch openni_launch openni.launch device_id:=invalid and am running setparam sim_time true and rosbag play fille.bag My bag file is working but I'm getting this from the openni

Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.

unused args [depth_registered_filtered] for include of [/opt/ros/indigo/share/rgbd_launch/launch/includes/processing.launch.xml] The traceback for the exception was written to the log file

any clue how to solve it?

I am pretty new to ros and even to linux. I faced the same error. What I did is the following: 1. go to the location provided in the error '/opt/ros/indigo/share/rgbd_launch/launch/includes/' and using nano or any other editor open the file 'processing.launch.xml'. 2. There will be several sections in there. Under the section 'Remapping Arguments', add this line

<arg name="depth_registered_filtered" default="depth_registered"/>

(just like the several others already there.)

  1. Then try to run 'roslaunch openni_launch openni.launch' again and see if this works.

It solved the error for me, but I do not know why this works.
