openni_launch pointclouds not published in rviz
Hi, openni_launch when ran gives the following error
[ERROR] [1324070131.410127857]: Tried to advertise a service that is already advertised in this node [/camera/depth_registered/image_rect_raw/compressed/set_parameters]
[ERROR] [1324070131.419698718]: Tried to advertise a service that is already advertised in this node [/camera/depth_registered/image_rect_raw/theora/set_parameters]
As given in the http://answers.ros.org/question/3210/complaint-from-openni_launch-on-already-advertised assuming that it doesn't make an impact i checked the rviz. I can see the image but the pointcloud is not being visualized. Even the status is "ok" for the pointcloud2 display in rviz. I echoed the topic that is subscribed by the rviz on the command line and could see the point clouds being displayed. Can someone tell what i am missing here. I saw in some posts that a dynamic reconfigure has to be done for this node. In that case how do i do it.
Thanks, Karthik
