VERSION
CCExtractor 0.88, Carlos Fernandez Sanz, Volker Quetschke.

COMMAND LINE
ccextractor video.mkv

I use CCExtractor on mkv files. There are different subtitle encodings. I see S_DVBSUB, S_VOBSUB, S_HDMV.

When I use CCExtractor on titles that are recorded on my DVR, I get "No captions were found in input." And zero length srt files.
There is clearly subtitles though, they appear in VLC and android players, in plex i get a dropdown indicating the subtitles to choose from.
When using CCExtractor on files that does not originate from the DVR, it works flawlessly it would appear.

I am interested to learn whether I am doing something wrong (arguments), or maybe get pointers where to look in code for places to experiment.
(I am completely new with ccextractor, but quite experienced with coding)

I think this is somehow related to offset calculations, maybe this issue https://github.com/CCExtractor/ccextractor/issues/723
Because dvr recordings are chopped off a live stream.

I think the problem is over reaching here. I need to read up on ccextractor with ocr parsing first.
