I have installed ROS (Indigo) on both a regular PC and an ARM embedded board (i.MX6x SABRE-Lite). Both run Ubuntu 14.04.

After launching freenect.launch on the PC almost 200 topics are created.

After launching it on the ARM-board only a few dozen topics are created.

I don't need all the extra topics, so its working fine for me, but my question is, where can I find the points where this differentiation is made. In the ROS sources, or in libfreenect, or in the ROS infrastructure?

I can't find it, hopefully someone here knows it...

UPDATE: if I do freenext_launch freenect.launch then rostopic list|fgrep camera|wc yields 194.

Thanks in advance, Sietse

"200 topics": are you sure? That seems a bit excessive ..

Do you have additional image transport or depth image transport plugins installed on your PC that you don't have installed on ARM?

Thanks Austin, I did have additional image transport plugins installed on the PC. That answers my question.
