Well, the hypothetical playlist rewrite seems to happen gradually.

It's important not to add any more dependency on id. So the idea is
just to use the minimal subset of function so that they will be easier
to replace. Either, don't implement that function as a playlist API
and move it inline where you need it, or translate the id before using
that function. This should be easy to do.

Value and parameter are terms that are too vague and certainly not
descriptive :)

I am going to be picky, but this parameter API is too obscure and too
vague. We don't want that level of flexibility in vlc, at least for
the sake of checking.

Instead of saying I don't like, here is the kind of API that we should
look to develop:

services_discovery:
- search* search_new()
- void search_set_filter_string(search*, const char *)
- vlc_array_t search_get_input_item_results_list(search*)
- event_manager* search_get_event_manager()
-> emit search_result_item_added
-> emit search_result_item_removed

This could even be refined.

ItemPut() name is also too vague, and seems to be unrelated to string
passing to the SD.

> The other 2, ItemGet and ItemDelete, are not used at the moment

Please don't implement them yet then.

Thanks for the answer and work, seems like a cool addition to VLC.

Pierre.
