bag_to_pcd failed to contact master
i'm trying to run 'bag_to_pcd' from the terminal but keep getting the following error..
[ERROR] [1320830633.224372085]: [registerPublisher] Failed to contact master at [localhost:11311]. Retrying...
rosrun pcl_ros bag_to-pcd points2.bag /camera/depth/points2 mr
where,
- points2.bag is my bag file
- /camera/depth/points2 is the topic
- mr is the directory where to put the pcd files
if i ctrl c out of it, the following comes up...
^Cterminate called after throwing an instance of 'ros::TimeNotInitializedException'
what(): Cannot use ros::Time::now() before the first NodeHandle has been created or ros::start() has been called. If this is a standalone app or test that just uses ros::Time and does not communicate over ROS, you may also call ros::Time::init()

and rosbag info points2.bag gives me...
