 Thank you very much. Would you please be so kind and clarify whether Dolby
 E can now be detected by ffmpeg and ffprobe?

 On the example TS file from one of the comments in this thread I get this:
 {{{

 And I'm not sure how to work with those .bin files from the other
 comments. Are we supposed to inform ffprobe/ffmpeg that input codec is
 Dolby E? Can you please supply an example?

 Thanks in advance.
