Why RTP packets are not recognized in the UDP protocol for Windows 10, and for Windows 7 everything is ok. I use wireshark version 3.6.3. Help me please

  • Was it a clean install on Windows 10? rtp_udp is disabled by default.

  • Check frame.protocols to see if another protocol grabbed it without adding to the tree.
    [Protocols in frame: eth:ethertype:ip:udp:someip]
    Disable someip_udp_heur.

Thank you, when I did the decoding of UDP in RTP, everything turned out and I got a good result. I'm just a beginner.

Yes, clean install Windows 10. Other protocols are decoded. It only occurred for this traffic.
