wireshark - Find dropped packets from pcapng-dump -

i need dropped packet count out of captured pcapng file. know stored in there, because when open in wireshark , go "comments summary" find following:

capture:    os: 64-bit windows 7 service pack 1, build 7601    capture application: dumpcap 1.12.6 (v1.12.6-0-gee1fce6 master-1.12)     \device\npf_{2005d0f6-4603-45a3-829f-fa6c40692419}:       dropped packets: 1 (0.962%)       capture filter: none       link type: ethernet       packet size limit 262144 bytes 

however, can't run wireshark info, need stdout output given capinfos. when run capinfos , statisics want out of file, except dropped packet count.

i find strange. mean capinfos-program outdated , can't extract information?
