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.
