Cannot Extract Subtitles from .VOB files

[Selur]

On DVDs one usually differentiates between:

• CC = closed caption are usually text base and usually come from broadcasts, but are allowed on DVDs. There are even commercial DVDs with closed captions. (these are basically SRT subtitles; see: A Technical Explanation of Placement and Format of DVD Closed Caption User Data Packets)
  
• Subtitles containing image based subtitles, these usually get extracted as vobsub (idx,sub) subtitles.
  
• Subtitles for the Deaf and Hard of Hearing (SDH), these are basically the same as the normal subtitles but add atmospheric comments (like 'background chatter' or 'music plays' or 'thunder in the background',...).
  

Embedded subtitles that are part of the image do not count as subtitles in the DVD specification, they are simply a part of the video stream.
Unlike DVDs, (UHD- and HD) Blu-rays only support image based subtitles.
Streaming media can have tons of different subtitle formats,..

The subtitles in the sample are valid closed caption subtitles and can be extracted as srt files using CCExtractor without a problem.
