I am using
cmd: /usr/bin/ccextractor -nobom --service all[ISO88591] -nofc -ts -12 -s 180 /home/dn/ramesh/191505_20201123020000.ts

its generating caption like

-rw------- 1 root root 205930 Nov 23 11:23 191505_20201123020000_1.srt
-rw------- 1 root root 0 Nov 23 11:04 191505_20201123020000_2.srt
-rw------- 1 root root 132090 Nov 23 11:04 191505_20201123020000.p1.svc01.srt
-rw------- 1 root root 76040 Nov 23 11:04 191505_20201123020000.p1.svc03.srt

why 191505_20201123020000_2.srt is empty, its should generate 608-cc3 caption.
