Comment (by smallishzulu):

 Well noted. I will follow your instruction.

 Yes, there is no error for impossible conversion. Conversion seems
 happened. However as I said, dvbsub is not displayable in any player. I
 thought the reason was related with timings/timestamps, however it is not.
 The problem seems like no dimension (canvas) information.

 I tried transcoding with VLC as well (dvbteletext to dvbsub). It has the
 same problem.
 (I tested it as it has some alternative dvbsub encoding code.)
