rb_player_gst_filter_add_filter ()

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.

rb_player_gst_filter_remove_filter ()

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.

The “filter-inserted” signal

void
user_function (RBPlayerGstFilter *player,
               GObject           *filter,
               gpointer           user_data)

The 'filter-inserted' signal is emitted when the tee element has been inserted into the pipeline and fully linked

Flags: No Recursion

The “filter-pre-remove” signal

void
user_function (RBPlayerGstFilter *player,
               GObject           *filter,
               gpointer           user_data)

The 'filter-pre-remove' signal is emitted immediately before the element is unlinked and removed from the pipeline

Flags: No Recursion
