Comment (by ExSport):

 After reading linked ticket, this problem is totally different.
 Problem described here is that internal subs (not external ones) have to
 be parsed beforehand what delays transcoding process by minutes what makes
 other side to close connection/pipe.
 E.g. mkv file with internal subs have to be extracted before the ffmpeg
 will burn them to the picture and will start to fill pipe with encoded
 results. This 4minutes delay every other side will forcefully close or
 disconnect from open pipe or connection.
