This interface allows a caller to add filter elements to the GStreamer playback pipeline.
gboolean rb_player_gst_filter_add_filter (RBPlayerGstFilter *player
,GstElement *element
);
Adds a new filter to the playback pipeline. The filter may not be inserted immediately. The 'filter-inserted' signal will be emitted when this actually happens.
gboolean rb_player_gst_filter_remove_filter (RBPlayerGstFilter *player
,GstElement *element
);
Removes a filter from the playback pipeline. The filter may not be removed immediately. The 'filter-pre-remove' signal will be emitted immediately before this actually happens.
struct RBPlayerGstFilterIface { GTypeInterface g_iface; /* virtual functions */ gboolean (*add_filter) (RBPlayerGstFilter *player, GstElement *element); gboolean (*remove_filter) (RBPlayerGstFilter *player, GstElement *element); /* signals */ void (*filter_inserted) (RBPlayerGstFilter *player, GstElement *filter); void (*filter_pre_remove) (RBPlayerGstFilter *player, GstElement *filter); };
