We have been considering turning the xine "engine" into a library already
and we came to the conclusion that this will be a good thing to do in the
near future. 

However, I don't think were are at that point yet. The reason for this is
that there are two major architectural changes that need to be done first
and I think each of them would break the library. One change is the
syncing on the system clock instead of the sound card (that'll be the xine
0.4.x series) and finally using more threads so xine takes up only the
computing power it needs and gets idle if there's nothing to do (xine
does busy waiting at the moment when playing a stream and there's
computing power left).

But if you want to you can of course look at our code (xine.h should give
you an impression of the xine "API" that exists at the moment) and you can
experiment with that library change already.

xine can seek now (use the slider or the number keys, e.g. 2 => 20% of the
stream). Xine can, however, only seek to a given byte position in the
stream (that's what's needed for DVD playback), it can't seek to a PTS -
which would be rather difficult anyway, since PTS can wrap around and thus
are not necessarily unique in a given stream.
