@sam-rke hi, I also meet the same problem while importing pcap file to matlab. search for a long time on internet, did not find related method.it seems no way. one .bag file can generate several pcd files, but one pcap file contains several pointcloud iamg. maybe need some formula to transfer. I don't have hardware sensor,it seems pcap file could be got from sensor directly.

HI @wangzhensuo actually pcap can be generated from Ouster Studio (as per Ouster Guidline) I'll be looking into it as I'll be getting Ouster Lidar soon. I am just stuck in

  1. How to capture .pcap with ouster driver code as it capture .bag file?
  2. How to convert .bag file to .pcap with code/library only?

Hope for the best. Thankyou

Hi @sam-rke, just so you know: the Python SDK records .pcap files, as shown in this example. If you have other questions,

Providing bag to pcap functionality is pretty low on our list of features, so I'm marking this as won't do. Given that most of the requests in this thread desired bag to pcap so that people could use Ouster Studio to examine their data, I would recommend checking out Python SDK if you don't need bags. If you need to record bag data, but also need it in pcap format, you can always use tcpdump to record pcaps while recording the bags. Hope that helps!
