Additional information

What is the recommended method to input SCC files into ccextractor on a non-Windows platform?

I can see that ccextrator can accept McPoodle Raw format...

Input formats:
       With the exception of McPoodle's raw format, which is just the closed
       caption data with no other info, CCExtractor can usually detect the
       input format correctly.

Therefore '-in=raw' would be the appropriate format.

The challenge is then how to get the SCC files into McPoodle raw format in a non-Windows environment. McPoodle includes SCC2RAW.exe (Windows Binary), but McPoodle's project is only compiled for Windows.

The ccextractor FAQ suggests that the ccextractor team ported McPoodle's code... "Lots of code came originally from McPoodle's tools (even though it was ported from Perl to C)", and ccextractor is thankfully cross-platform. Did the result of this porting process expose an SCC2RAW method in a way that could be used to allow scc as an input into ccextractor?

(or does anyone know of a cross-platform port of McPoodle suite which I may have missed?)

Thanks for a great tool.

Resolved by running SCCTOOL's perl script rather than the Windows binary.

Let's leave this open if there's a problem with it :-)

Worked perfectly for SCC > Raw > SRT using SCC_TOOLS per scripts on macOS

$ curl --silent --location --request GET "https://archive.org/download/cc_sample/cc_sample.scc" -o cc_sample.scc
$ dos2unix --newfile cc_sample.scc cc_sample_dos2unix.scc
$ perl scc2raw.pl cc_sample_dos2unix.scc cc_sample_dos2unix.bin
$ ccextractor -debug -in=raw -out=srt -utf8 cc_sample_dos2unix.bin -o cc_sample_dos2unix.srt

It is more serious

Good

This one should be ok to close, as the above flow worked for SCC > RAW> SRT.

There was an issue for SCC > RAW > VTT, which I have opened under its own ticket, because it is specific to VTT. https://github.com/CCExtractor/ccextractor/issues/1294

Thanks!
