A second is a lot; it probably depends on which application you use;
Totem (ok, it's a GNOME app, so what) is instant in most cases. Also, it
depends on the media format (that's an implementation bug). Our matroska
demuxer, for example, is a big offender here.

That said, yes, we're aware of some issues in this area and they're on
my list. If they're important for a specific project or subproject that
we especially care about for some reason, we can raise priority.
