    • DROP

      static final int DROP
      drop data in data probes. For push mode this means that
      the data item is not sent downstream. For pull mode, it means that
      the data item is not passed upstream. In both cases, no other probes
      are called for this item and %GST_FLOW_OK or %TRUE is returned to the
      caller.

    • OK

      static final int OK
      normal probe return value. This leaves the probe in
      place, and defers decisions about dropping or passing data to other
      probes, if any. If there are no other probes, the default behaviour
      for the probe type applies ('block' for blocking probes,
      and 'pass' for non-blocking probes).

    • REMOVE

      static final int REMOVE
      remove this probe, passing the data. For blocking probes
      this will cause data flow to unblock, unless there are also other
      blocking probes installed.

    • PASS

      static final int PASS
      pass the data item in the block probe and block on the
      next item. Note, that if there are multiple pad probes installed and
      any probe returns PASS, the data will be passed.

    • HANDLED

      static final int HANDLED
      Data has been handled in the probe and will not be
      forwarded further. For events and buffers this is the same behaviour as
      %GST_PAD_PROBE_DROP (except that in this case you need to unref the buffer
      or event yourself). For queries it will also return %TRUE to the caller.
      The probe can also modify the #GstFlowReturn value by using the
      #GST_PAD_PROBE_INFO_FLOW_RETURN() accessor.
      Note that the resulting query must contain valid entries.
