    • run

      void run(@Nullable Pad newPad)
      a new GstPad has been added to the element. Note that this signal will usually be emitted from the context of the streaming thread. Also keep in mind that if you add new elements to the pipeline in the signal handler you will need to set them to the desired target state with gst_element_set_state() or gst_element_sync_state_with_parent().

    • upcall

      default void upcall(MemorySegment sourceElement, MemorySegment newPad)
