New problem => your best bet is to open a new thread, quoting the whole
command line as well as whole output.

Only advice I can give you are:
- Check that your ffmpeg knows the drawtext filter (mine which dates
  from yesterday does not know it), using ffmpeg -filters / Check that
  the ffmpeg you call is the one you think if you have more than one on
  the same system in different places (which ffmpeg).
- Check that all required arguments are there (I would expect
  coordinates).
