[ros-users] openni_camera not publishing any data

[Tom Birch]

I've been trying to reproduce the RGBDSLAM demo, but I can't even get over
the first hurdle of getting openni_camera to work. I'm running Ubuntu 10.10
in VMware on top of OSX, but I've verified that the kinect works in this
setup by running the freenect demos. Is it possible the freenect driver is
somehow conflicting with the openni driver?

I've tried downloading the source for the openni_ros packages, or installing
via apt-get, but they both have the same behaviour. If I run image_view
(rosrun image_view image_view image:=/camera/rgb/image_color) then after a
while I get this message:

terminate called after throwing an instance of
'openni_wrapper::OpenNIException'
  what():  virtual void openni_wrapper::OpenNIDevice::startImageStream() @
/home/local/ros/openni_ros/openni_camera/src/openni_device.cpp @ 159 :
starting image stream failed. Reason: Xiron OS got an event timeout!
[openni_node1-1] process has died [pid 10732, exit code -6].
log files:
/home/local/.ros/log/d0cbd57a-5e73-11e0-a067-000c29bc217f/openni_node1-1*.log

There don't seem to be any error messages at all in either of the logs, but
I can post them somewhere if anyone is interested.

Has anyone seen anything like this? I'm just about to dive into the code and
debug it myself, but I thought I'd check here first.

cheers,
Tom
