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)? {YES/NO}
    Supposedly it was fixed in 2017. I do not know what the version would have been at that time.
  • What platform did you use? {Window/Linux/Mac}
    Windows
  • What were the used arguments?

Additional information

Hello,

I am using version 0.94 to try and extract embedded captions from a .ts file.

Here is what happens in the Log when I attempt to extract the captions:

CCExtractor 0.94, Carlos Fernandez Sanz, Volker Quetschke.

This issue looks very similar to issue #752. I can load with video with VLC and get captions to show up without any problems.

I will be sending the input file to you privately.

Thank you,
Coleman

Please share a direct link to the specific file. I got a shared folder that doesn't open (somehow it redirects to my own trash).

@colemank1 commented on GitHub (Apr 14, 2023):

Apologies. After sharing the file, I deleted it from the folder. The reason
being that I was continuing to troubleshoot, and I noticed a very
frightening legal warning in the file, stating that it is strictly
prohibited to redistribute the content in any form.

I will attempt to reproduce the error with a different input file - one
that doesn't have such a strict set of restrictions. Once I've verified
that it's reproductible, I will send you the new file.

Thanks,
Coleman Kintop

This has been a problem for awhile with the newest version. Either get the old GUI "0.89" or a slightly older version "https://github.com/CCExtractor/ccextractor/releases/tag/v0.90"
