Comment (by Selcuk Ozturk):

 As far as I can find out, eia_608 closed captions in mpegts streams don't
 have their own stream. The only way to extract them is
 "movie=filename.ts[out+subcc]" which kind of converts them to a stream.
 All google searches point to this syntax. If you can give me your
 suggested syntax, I can try it.
