Frankly, it makes zero sense for a media to be tied to an instance in the first 
place. input_item_t is not tied to an instance. I think you're looking at it 
from the wrong angle.

Of course, an instance is necessary for certain operation on the media: 
playing, parsing, etc. In all those case, we should do one of the following:
1) implicitly use the instance from the actor object (as media player does)
2) create an instance automatically,
3) take an explicit instance pointer as parameter.

Creating an instance is very cheap - if there is already at least one in the 
process so option 2 is actually very viable for simple case like saving 
metadata.

It's also highly desirable where a consistent result is expected/assumed such 
as preparsing, whose result should depend on media options but *not* on the 
LibVLC instance.
