Not very experienced about subtitles and all, AFAIK subtitles support
in FFmpeg is still a bit... rudimentary.

But if you want subtitles in output you need a format which supports
them, I know matroska (.mkv) should do.

As for hardcoding subtitles right onto the video, I'm afraid we still
miss that facility (subtitles filtering + video overlaying seems the
right solution), correct if I'm wrong.
