Can't run remote capture after upgrading from 3.2.8 to 3.4.0

Script to run capture:

plink.exe -batch -ssh -pw xxx user@host "sudo /usr/sbin/tcpdump -Unqi plc0 -s 0 -w -"   | Wireshark -k -i -

Wireshark 3.4.0 shows nothing (packets to host transmitted successfully)

Downgrading back to 3.2.8 resolves the problem.

Have you ever looked at using the sshdump extcap interface?

Capture from stdin in Windows is currently broken and will be fixed in 3.4.1. The fix is under review here.
