How do I check that rosbag message is correct version?
I have a program that reads in a rosbag and does something with a custom ROS message. Occasionally the ROS message definition changes and can produce unexpected results if the code was compiled with an older definition of that message. How can I implement error checking to verify that the ROS messages in the rosbag match the ROS message definition that my code was compiled with? Can I do this by checking md5sums? I am working with a pcl::Pointcloud template if that makes any difference.
Please edit your description to show us the exact ros .msg file you are using. As far as I know,
pcl::PointCloud<T>is not a ros message. You edit using the "edit" button near the end of the description.
