@unicode45, can you please detail the issue a bit more? I'm unable to see what video file was used and what exactly were the passed commands.

That'll help us solve the issue faster :)

@unicode45 Getting a little deeper into the issue, we never had an option like that. I've removed the instance of it in the help, I apologize for the misleading :D

Well, o1 and o2 were valid options. Don't remember what we replaced them
with though.

Here's a sample Korean ts file that I used.
https://drive.google.com/file/d/0B8AjqtxcLQDxeW5qT0RGSzQzZm8/view

I tried -o1 and -o2 option becuase *.p1.svc01.srt always containts the right Korean subtitle contents while .srt is empty.

@unicode45 Are you sure this is the right file? I'm doubtful since ffprobe shows no subtitle stream and even vlc is not able to detect/play any CC.

I've checked with MediaInfo and EIA-708 stream found.

Hey @unicode45, please have a look at the issue that was created two years back regarding the same.

For eg.
To extract data from channel 2 of the stream, you can give a command like,

ccextractor [input_file] -2 -o [output_filename]

The -o [output_filename] can be omitted if you want to stick to default naming.

@FossPrime commented on GitHub (Jun 5, 2019):

These docs are really misleading... -2 seems to be broken badly with multi track MP4's.

https://www.ccextractor.org/doku.php?id=public:general:command_line_usage

 -o outputfilename: Use -o parameters to define output filename if you don't
                       like the default ones (same as infile plus _1 or _2 when
                       needed and file extension, e.g. .srt).
                           -o or -o1 -> Name of the first (maybe only) output
                                        file.
                           -o2       -> Name of the second output file, when
                                        it applies.

Yes. -o1 and -o2 were probably one of the first supported parameters and
they came from the 608-only days, where you could have 2 languages only.

If multilanguage doesn't work in .mp4 it's not really an issue with -o2
(which it's likely to just be implemented in 608).
