Hi, I am using VLP16 to fuse the pointscloud with VLP32. But when i using the driver to replay pcap, it seems missing some angle data and the missing data is oritenting when replay pcap. I am sure that the pcap data is right because of verified by VeloView. See as following pictures:

@TheGreatGalaxy - If you record these data using the real sensor and record with a rosbag, does replaying the rosbag show the same effect or is it only when you replay the pcap file using the driver? Have you tried replaying the pcap file with something like Wireshark and having the Velodyne driver connect to the replayed data? What does this show?
