Your ffmpeg configure line is blank. From subtitle filter documentation:

  "To enable compilation of this filter you need to configure FFmpeg
  with --enable-libass."

See:
http://ffmpeg.org/ffmpeg-filters.html#subtitles

The ass filter also depends on libass.

Please do not send multiples of the same question to the mailing list.
