As packet duration is not stored inherently in MPEG4 containers,
subtitles have their duration expressed by storing an additional
empty packet with a pts matching the desired end time of the real
subtitle. Additionally, it is generally expected that all streams
start at time = 0, so an empty packet needs to be inserted at the
beginning of the stream, before the first real subtitle.
Unfortunately, ffmpeg lacks a proper way to express that a subtitle
might map to multiple packets, so the muxer is the only place we
can handle this.

There is basic support for muxing chapter information into the
Apple Quicktime format already, but there are two errors which
prevent correct detection on the player side.
1) A special apple 'text' atom needs to be included inside the
gmhd atom.
2) The *different* 'text' atom inside the 'stsd' atom needs a
proper header.
With these changes, the chapters are now picked up by Apple
players and reported correctly by tools like mediainfo and mp4chaps.
v3 Update: The stub TextSampleEntry creation is moved to where the
chapter track is created so it's now specific to this track.
