are internal structures, unexposed to the end-user
as you suggest.

For me, a seekpoint describes an offset in the audio file,
and enables any player to jump to instantly jump to that
position.

For instance, if you pack up an a collection of audio tracks
into a single FLAC file, there is a strong need for seeking !
It is common, typically in classical music, to have
up to 40 tracks on a single CD (exemple: sets of variations, etudes
...) and it is much more handy to join them into a single FLAC,
instead of having tens of mini FLAC files.

But then you need seekpoints.

So the questions still holds:
1. how can i check if the seekpoints i specified when encoding are actually there ?
2. what media players are aware of FLAC seekpoints ?
