One issue I noticed is with the seeking.

As an application you usually want to select an element of the TOC tree or a
few elements with the same parent. Then playback starts and you might want to
skip to the next chapter but continue playback of what was specified before.
For this I'd suggest:

  GST_SEEK_TYPE_SET in GST_FORMAT_CHAPTER will set a new chapter selection that
will be played, i.e. the full subtree of all selected elements with the same
parent element.

  GST_SEEK_TYPE_CUR in GST_FORMAT_CHAPTER will keep the previous selection but
will seek to the specified chapter.

  GST_SEEK_TYPE_CUR in other formats will be relative to the chapter selection
done with GST_SEEK_TYPE_SET in GST_FORMAT_CHAPTER and relative to the current
playback position.

  GST_SEEK_TYPE_SET in other formats after a GST_SEEK_TYPE_SET in
GST_FORMAT_CHAPTER will be handled relative to the selected chapters.
