I'd like to send you a video sample, which doesn't work well with CCExtractor in hope you can fix it, or tell me what's wrong with the file.

Download link:
https://docs.google.com/uc?id=0B5foVtK-k1OPUEEtSmQyTEZDLUU&export=download

I've tried this command:
ccextractor -noteletext -12 -in=ts S06E11_raw_1080i.ts

And the output is here:
http://svimik.com/S06E11_raw_1080i_1.srt

Indeed there are some captions, but it's somehow broken. Is it an input file fault, or there is something that CCExtractor can't understand?

I have also tried the ffmpeg with following command:
ffmpeg -f lavfi -i "movie=S06E11_raw_1080i.ts[out0+subcc]" -map s S06E11_ffmpeg.srt

ffmpeg did it somehow better (at least, there is a clean text, although with some words and lines still missing).
Here is ffmpeg output: http://svimik.com/S06E11_ffmpeg.srt

I thought this was related to CEA-708 but I'm not sure any more... ffprobe shows this:

Input #0, mpegts, from 'My.Little.Pony.Friendship.is.Magic.S06E11.HDTV.1080i.DD5.1.MPEG-2.ts':

Program 1

Stream #0:10x20f: Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz, 5.1(side), fltp, 384 kb/s

So no subtitles, but VLC shows CC1 up to CC4

And there's some text...

Yes, there are some subtitles, but I'm not sure about the format.
The last version from git extracts much better (the garbage is gone), but some words are still missing (in VLC there is same problem).
Is the file broken or there's just some unknown encoding?

As of 0.82 on windows 10,, the output is now in plaintext. However, a lot of the text is quite garbled. No warnings or segfault.

Can't say. These files was produced by @SpazzDHN.
Never actually had a contact with him (I tried once, but got ignored - maybe you get more luck).
Btw, sometimes he publish captions too, without any flaws. It's still a mystery to me how he extract it.

CEA-608 is really corrupt in files from this ripper (I've checked binary in #426), but CEA-708 looks ok.
