View source for LibVLC Media List Management

== Global Description of the available objects ==
The atomic item that represent a media that you can play is a '''media_descriptor''' in LibVLC.

A '''media_list''' is an object that contains several ''media_descriptor''. You can add items to that media_list.

A '''media_list_view''' is an object that provide a way to see/browse a media_list ('''Read-only'''). There are currently two kind of media_list_view:
* a '''flat''' media list view
* a '''hierarchical''' media list view

You can play a media_list using a '''media_list_player'''.

== A media descriptor can contain a media list ==
A playlist downloaded from Google video has a corresponding media_descriptor. This media_descriptor has several subitems. You can access them through libvlc_media_descriptor_subitems() which returns a media_list.


This explains how a media_list can be hierarchical. To browse it you'll use libvlc_media_list_hierarchy_view(). To view the all the item without hierarchy use libvlc_media_list_flat_view().

== Sample Code ==

 void setup_media_list( libvlc_instance_t * p_vlc, libvlc_drawable_t window )
 {
     libvlc_exception_t e;
     libvlc_media_list_t * p_ml;
     libvlc_media_list_player_t * p_mlp;
     libvlc_media_instance_t * p_mi;
     libvlc_media_descriptor_t * p_md1, *p_md2;
  
     libvlc_exception_init( &e );
  
     p_ml = libvlc_media_list_new( p_vlc, &e );
     quit_on_exception( &e );
    
     p_md1  = libvlc_media_descriptor_new( p_vlc, "http://mycool.com/movie1.avi", &e );
     quit_on_exception( &e );
  
     p_md2  = libvlc_media_descriptor_new( p_vlc, "http://mycool.com/movie2.avi", &e );
     quit_on_exception( &e );
  
     libvlc_media_list_add( p_ml, p_md1, &e );
     quit_on_exception( &e );
  
     libvlc_media_list_add( p_ml, p_md2, &e );
     quit_on_exception( &e );
  
     libvlc_media_descriptor_release( p_md1 );
     libvlc_media_descriptor_release( p_md2 );

     libvlc_media_list_player_set_media_list( p_mlp, p_ml, &e );
     quit_on_exception( &e );
  
     /* Use a given media instance */
     libvlc_media_list_player_set_media_instance( p_mlp, p_mi, &e );
     quit_on_exception( &e );
  
     /* Get our media instance to use our window */
     libvlc_media_instance_set_drawable( p_mlp, window, &e );
     quit_on_exception( &e );
  
     /* Play */
     libvlc_media_instance_play( p_mlp, &e );
     quit_on_exception( &e );
  
     /* Let it play forever */
     while(1) sleep(300);
