When trying to open MPEG2 Transport stream files, ccextractor now fails with "Unable to open" & error code 6.

By comparison, telxcc has no problem extracting teletext subtitles from such a file.

CCExtractor 0.78 CLI installed on OS X through Homebrew.

Hello,

could you try running .80 .79, which is the latest version released a week ago?

I do not know how to build ccextractor, so I will have to wait until the version becomes available through Homebrew on the Mac. Then I can try it out.

I don't own a mac myself, but from what I see in the mac folder of the repository, all you need to do is perform these steps:

  • install the Apple Developer Tools
  • download the latest 0.79 source files from SourceForge
  • extract the zip
  • open the terminal
  • navigate to the mac folder of the extracted folder (e.g. cd ~/Downloads/ccextractor0.79/mac)
  • run the command which should compile ccextractor for you (./build.command)

If all goes well and there are no errors, you should have a ccextractor executable in the same folder. If an error occurs, it would be nice if you could open a new issue for this, so we can update the mac build command (as @cfsmp3 noted, none of us contributors owns a mac, so we can't test it every time we release unfortunately).

If you don't want to do this, would it be possible to make a small sample available, so we can test it on Linux with the current version (and with 0.78 as well) to confirm the issue?

Thanks for the instructions,

unfortunately it fails to build on my Mac, so I have created a new issue as per your suggestion.

I have tested this with a build of 0.79. However, it still produces the error message

Unable to open 


Error: Failed to determine total file size.

That means it can't find or open the input file.

Sorry, this was caused by an error in my extraction script.

However, it would be great if in the case of such an error the name of the file were listed.
I mistakenly thought that CCExtractor could not open the video file; instead the path to the srt file to be created was incorrect.
With a more verbose error message, I would have spotted my error immediately.

Solved in current github, please reopen if a new sample that fails proper detection appears
