ffmpeg doesn't map data streams by default. You can either add
  -map 0
to your command line, telling ffmpeg to map all streams, or explicitly
map the data stream with
  -map 0:v -map 0:a -map 0:d
(essentially telling ffmpeg of each and every stream you wish to map.

See also this, where a similar question was answered:

By the way, we usually kindly ask you to post the complete, uncut
console output of your ffmpeg command, as it provides useful
information for analysis of such issues.
