## Description

Pads managed by a GstAggregor subclass.

This class used to live in gst-plugins-bad and was moved to core.

## Functions

### gst_aggregator_pad_pop_buffer ()

    GstBuffer *
    gst_aggregator_pad_pop_buffer (GstAggregatorPad *pad);

Steal the ref to the buffer currently queued in `pad` .

#### Parameters

pad | the pad to get buffer from |

#### Returns

The buffer in `pad` or NULL if no buffer was queued. You should unref the buffer after usage.

### gst_aggregator_pad_peek_buffer ()

    GstBuffer *
    gst_aggregator_pad_peek_buffer (GstAggregatorPad *pad);

#### Parameters

pad | the pad to get buffer from |

#### Returns

A reference to the buffer in `pad` or NULL if no buffer was queued. You should unref the buffer after usage.

### gst_aggregator_pad_drop_buffer ()

    gboolean
    gst_aggregator_pad_drop_buffer (GstAggregatorPad *pad);

Drop the buffer currently queued in `pad` .

#### Parameters

pad | the pad where to drop any pending buffer |

#### Returns

TRUE if there was a buffer queued in `pad` , or FALSE if not.

### gst_aggregator_pad_is_eos ()

    gboolean
    gst_aggregator_pad_is_eos (GstAggregatorPad *pad);

#### Parameters

pad | an aggregator pad |

#### Returns

`TRUE` if the pad is EOS, otherwise `FALSE`.

### gst_aggregator_pad_has_buffer ()

    gboolean
    gst_aggregator_pad_has_buffer (GstAggregatorPad *pad);

#### Parameters

pad | the pad to check the buffer on |

#### Returns

`TRUE` if the pad has a buffer available as the next thing.

### struct GstAggregatorPadClass

    struct GstAggregatorPadClass {
      GstPadClass   parent_class;

      GstFlowReturn (*flush)       (GstAggregatorPad * aggpad, GstAggregator * aggregator);
      gboolean      (*skip_buffer) (GstAggregatorPad * aggpad, GstAggregator * aggregator, GstBuffer * buffer);
    };

#### Members

`flush` () | Optional Called when the pad has received a flush stop, this is the place to flush any information specific to the pad, it allows for individual pads to be flushed while others might not be. |
`skip_buffer` () | Optional Called before input buffers are queued in the pad, return `TRUE` if the buffer should be skipped. |
