Can statsprocessor & hashcat works together?
sp64 hashcat.hcstat --pw-min=8 --pw-max=8 -stdout | hashcat-cli64 -m 2500 *.hccap
yes. but hashcat does not support reading from stdin, so you'd need to create a named pipe and use that as a wordlist.
an example please?
man 1 mkfifo
thank you very much! Smile where I can find "man 1 mkfifo" there?
with aircrack-ng it works:

sp64 hashcat.hcstat --pw-min=8 --pw-max=8 --markov-classic -stdout | aircrack-ng -b 00:19:CB:74:EB:E8 -w- ZyXEL.cap
