How to extract subtitles from TS (transport stream) files

Fallback Image

It’s possible to extract TeleText subtitles from TS or Transport Stream files recorded by the VU Uno satellite box using a tool called ccextractor.

Below guide is used on Mac OS X, using CCExtractor v0.78.

  1. Download the source code of CCExtractor here: http://ccextractor.sourceforge.net/download-ccextractor.html
  2. Extract the source code to a folder if not done automatically.
  3. In Terminal locate the folder called “mac” within the extracted folder
  4. Run the following command: sudo bash ./build.command
  5. Type in your password if requested, and wait for the build to complete.
  6. You should now find a file called “ccextractor” in the folder.
  7. To extract subtitles from a file use the below command:

ccextractor -startat mm:ss -endat mm:ss -autoprogram  -out=srt -bom -utf8 -teletext -tpage yyy /path/to/my/file/name.ts

-tpage: Is the teletext page containing the subtitles for Danish TV this is normally page 399.

-startat: The point in time when the the extraction should start formatted in minutes:seconds

-endat: The point in time when the extraction should end formatted in minutes:seconds.

The above will extract the TeleText into a .srt file encoded in UTF8 and placed in the same folder as the input file.

Note: The extracted srt file will need to be synchronised with the video afterwards. To do this, you can use the online service called SubShifter (http://subshifter.bitsnbites.eu) where you upload the file, provide the off-set you need to match with your encoded video, and you will get a new file with the required off-set.

Happy extracting 🙂
