Error playing my rosbag file #19

Closed Doublehes closed 4 years ago

Doublehes commented 4 years ago

When I was playing my own rosbag file recorded by livox_viewer, i got an error:

[ERROR] [1599999355.900913770]: Client [/livox_scanRegistration] wants topic /livox/lidar to have datatype/md5sum [sensor_msgs/PointCloud2/1158d486dd51d683ce2f1be655c3c181], but our version has [livox_ros_driver/CustomMsg/e4d6829bdfe657cb6c21a746c86b21a6]. Dropping connection.

I do not know why it happened? How can I solve this problem?

I met the same problem wrong pointcloud type set the arg "output_type" to "1" in the file lvx_to_rosbag.launch then convert .lvx to rosbag

Doublehes commented 4 years ago

all right, solving by changing the output_type in the file lvx_to_rosbag.launch
