awk script to check for stuck subtitles

[mrfragger]

awk script to run to detect any stuck subtitles

for f in *.vtt *.srt ; do printf "%s\n" "$f" ; awk -F ":" '/[0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{3} -->/ {if ($2>$4 || $2<$4-1 ) print " Line# "NR": " $1":"$2" "$4 }' "$f" | awk '!/59 00/' ; done

Ran it on 254 audiobooks transcribed and 16 had this problem. Almost all were done with whisper.cpp 1.4.0 using medium.en model

This shows the output...if there is no problem then it just prints the filename of the audiobook subtitles. Just changed real titles to audiobook1, audiobook2 for demonstration purposes.

example

audiobook17.vtt
        Line# 19040: 04:09 56
        Line# 22400: 04:56 10
        Line# 82120: 18:27 29
        Line# 82256: 18:29 27

this one one needs to replace 56 min mark with 10 and the 29 min mark with 27 to correct subtitles from sticking

This script will ignore any problems if srt or vtt doesn't have an hour timecode for the first 60 mins
00:00.000 --> (this is rare and will be skipped the first 60 mins to check for stuck subs)
instead of
00:00:00.000 --> (almost all are like this as they should be)
