Folks,
I am subscribing to a compressed image published (or republished) by image_proc (it takes my rgb_raw, and publishes rectified rgb and mono images, including compressed versions).
But when I subscribe to the compressed images (rgb or mono), I get these messages:
[ERROR] [1479358743.735774954]: Tried to advertise a service that is already advertised in this node [/v_control_node/compressed/set_parameters]
This is my subscriber:
camera_track_sub_ = it_.subscribeCamera("/camera/rgb/image_rect", 2,
&MyNodeClass::ImageCb, this,
image_transport::TransportHints("compressed"));
// I assume TransportHints converts "/camera/rgb/image_rect" to "/camera/rgb/image_rect/compressed"
I have ROS indigo, and Ubuntu 14.04.
