Hello there,
Please, I have a video file with MPEG-TS format (Transport Stream) and 2 text streams with closed caption data embedded into the file (EIA 608 / EIA 708), but unfortunately the CCExtractorGUI is not able to extract the closed caption data because the program seems to stuck in 0% with a message:
"Found large gap(4874420) in PTS! Trying to recover ..."
The command line with all parameters set in the GUI is as follow:
C:\Program Files (x86)\CCExtractor\ccextractorwin.exe --gui_mode_reports -in=ts -autoprogram -out=txt -bom -utf8 [+input files]
testTS_subtitles_RTMP_2.zip

Please find attached the video file with MPEG-TS format to take a look at your side and screen shoots with media information and VLC showing the subtitle tracks with closed caption 1:
. Could you give some directions in order to find out the issue?
Thank you very much

Can't reproduce, seems fixed in current master. Please reopen the issue if needed.

I have this same issue with large gaps in certain files. Unfortunately I cannot give samples, but here is the output.
Tried versions: 0.85 (windows 10) and 0.86 (ubuntu).
Is there any fix on this? It does indeed work in some of the files, although there is similar timestamp issues.
