I'm trying to use the standard openni2.launch file from openni2_launch, but with reduced depth resolution. So either mode 8 or mode 11. Is there a way to do so without having to overwrite the openni2.launch and device.launch.xml and adding the arguments/parameters myself? Or am I missing the obvious way? And to be sure about it, I want to set the mode in the launch file that includes the openni2.launch, so no dynamic reconfigure, or rosparam set solutions...
