In raising this issue, I confirm the following:

  • I have read and understood the contributors guide.
  • I have checked that the bug-fix I am reporting can be replicated, or that the feature I am suggesting isn't already present.
  • I have checked that the issue I'm posting isn't already reported.
  • I have checked that the issue I'm porting isn't already solved and no duplicates exist in closed issues and in opened issues
  • I have checked the pull requests tab for existing solutions/implementations to my issue/suggestion.
  • I have used the latest available version of CCExtractor to verify this issue exists.
  • I have ticked all the boxes in this section and to prove it I'm deleting the section completely to remove boilerplate text.

Necessary information

  • Is this a regression (i.e. did it work before)? NO
  • What platform did you use? Linux (Linux hp 5.15.61-1-lts #1 SMP Wed, 17 Aug 2022 15:11:32 +0000 x86_64 GNU/Linux )
  • What were the used arguments? ccextractor -stdout -quiet input.mkv

PS: I downloaded and renamed below file.

Additional information

Expected: Output on stdout/terminal
Actual: Output on multiple srt files

How can I get all/one CC output on stdout instead of creating multiple files?

I'm working on this.

I've successfully built the latest checkout from source and reproduced this bug. Currently, I'm exploring the codebase to get familiar with it. I'll post here as I make progress towards identifying and fixing this issue.

I've made a pull request fixing this issue for the particular case of .mkv or Matroska input files with multiple CC tracks.

I do not see any new version on Arch User Repository since I posted this issue. I won't be able to compile myself this month due to timing constraints.

Hence, I won't be able to confirm the existence of the issue as of now.

Closing for now. Feel free to reopen when you have a chance to verify.
