camera1394 node and nodelet crash with theora subscriber
I am using camera1394 to connect to a Point Grey Grasshopper Express via a pc express card. Yesterday, I updated Fuerte in Ubuntu 12.04 using apt-get for the first time in month or so. Since the update, whenever I launch a node or nodelet that subscribes to the theora topic published by a camera1394 node or nodelet, the camera1394 instantiation segfaults with the error:
Unable to convert from 'mono8' to bgr8
I can replicate this error message and crash with any these node test cases:
rosrun camera1394 camera1394_node
rosrun camera1394 camera1394_node _video_mode:=640x480_mono8
rosrun camera1394 camera1394_node _video_mode:=format7_mode0
and these nodelet test cases:
rosrun nodelet nodelet standalone camera1394/driver
rosrun nodelet nodelet standalone camera1394/driver _video_mode:=640x480_mono8
rosrun nodelet nodelet standalone camera1394/driver _video_mode:=format7_mode0
Launched along with:
rosrun image_view image_view image:=/camera/image_raw theora
Any camera1394 node or nodelet will segfault. On shut down of the image_view node after a camera1394 crash, this is printed to the terminal:
Inconsistency detected by ld.so: dl-close.c: 759: _dl_close: Assertion 'map->l_init_called' failed!
For any of the camera1394 test cases I can successfully view the images with:
rosrun image_view image_view image:=/camera/image_raw raw
rosrun image_view image_view image:=/camera/image_raw compressed
Below is the output from a couple of my camera1394 node and nodelet tests. To get the final error and segfaults, I launch an image_view node listening to the theora topic in another terminal as above:
