Originally created by @bwhansen on GitHub (Aug 24, 2014).

Hey, think I found a bug...

My input files are m4v with CEA-608 stream (iTunes). If I output to SRT it works fine. But attempting to output to RAW / DVDRAW / BIN doesn’t work (output files are empty.)

Command line:
C:\Program Files (x86)\CCExtractor\ccextractorwin.exe --gui_mode_reports -in=mp4 -autoprogram -out=raw -o "C:\somefolder\s01e01_ccextract.raw" -latin1 --nofontcolor --notypesetting -noteletext [+input files]

The only option I’m changing (other than the output file name) is the –out argument. CCExtractor GUI "Preview" text area displays all captions as per normal every time, but unless output is set to SRT the files are empty.

CCExtractor 0.73 (also tested with CCExtractor 0.69)
Windows 8.1 Pro 64-Bit with UAC enabled; NTFS file system; Visual C++ 2013 Runtime installed.

Happy to answer any question, but go easy on me - I'm a CC n00b.

The m4v is uploading to the link I sent you on Skype. It will be available within 45mins.

This issue is still active. I have a wtv file with eia 608 CC. It extracts to srt format properly, but throws a SegFault if set to bin output:

File seems to be a WTV, enabling WTV mode
Analyzing data in general mode
  0%  |  00:00Segmentation fault

raw doesn't work, either. It doesn't produce SegFault; rather, reads whole file and indicates success but output file is only 4 bytes long.

PS This is on Linux building the latest code from github (i.e. c3d00d80f5 )

OK, I'll look into it asap so it's fixed in 0.76.

Can you submit a sample that causes the crash?

The sample used in this issue (.wtv) format has repeated CC in output(.srt). I am facing this in most of .wtv format files.

@mailumangjain I'm not sure if this is a bug. I think it's meant to mimic as closely as possible the CC you would see on TV. On TV, CC often scroll with the dialogue, whereas the srt format is static and must be redrawn to the screen at each specified timecode.

I think there is also a command-line flag that will limit repetition when creating srt files.

This issue still happens on 0.88, other formats work normally. I also tried using SCC_RIP and it gives no caption found when the caption stream is CEA-608. oops, wrong, the cea-608 in the sample is a raw .c608 file
Sample iTunes preview video
I don't know any tools that can convert raw C608 to SCC
