[vlc-devel] [PATCH 1/2] input: add vlc_InputItemPreparseEnded event

[Thomas Guillem]

This event is sent from playlist/preparsed thread to notify when an item is
preparsed. This event is sent when the preparse function terminate, ie. when
meta and sub items are parsed. It is also sent when the preparse function fails
to parse anything.
