I have tried --

rosrun velodyne_driver velodyne_node _model:=VLP16 _pcap:=/your/pcap/path/data.pcap _read_once:=true   

AND

rosrun rosbag record -O your_vlp16_070815.bag /velodyne_packets      

In separate terminals

The output is a *.bag.active and if I try to repair this it gives me *.bag.orig.active.

And also please advice how to play this .bag file in RVIZ.
