## Includes

## Description

Provides a base class for RTP depayloaders

## Functions

### GST_RTP_BASE_DEPAYLOAD_SINKPAD()

    #define GST_RTP_BASE_DEPAYLOAD_SINKPAD(depayload) (GST_RTP_BASE_DEPAYLOAD (depayload)->sinkpad)

### GST_RTP_BASE_DEPAYLOAD_SRCPAD()

    #define GST_RTP_BASE_DEPAYLOAD_SRCPAD(depayload)  (GST_RTP_BASE_DEPAYLOAD (depayload)->srcpad)

### gst_rtp_base_depayload_push ()

    GstFlowReturn
    gst_rtp_base_depayload_push (GstRTPBaseDepayload *filter,
                                 GstBuffer *out_buf);

Push `out_buf` to the peer of `filter` . This function takes ownership of `out_buf` .

This function will by default apply the last incomming timestamp on the outgoing buffer when it didn't have a timestamp already.

#### Parameters

filter | a GstRTPBaseDepayload |
out_buf | a GstBuffer |

#### Returns

a GstFlowReturn.

### gst_rtp_base_depayload_push_list ()

    GstFlowReturn
    gst_rtp_base_depayload_push_list (GstRTPBaseDepayload *filter,
                                      GstBufferList *out_list);

Push `out_list` to the peer of `filter` . This function takes ownership of `out_list` .

#### Parameters

filter | a GstRTPBaseDepayload |
out_list | a GstBufferList |

#### Returns

a GstFlowReturn.

## Types and Values

### struct GstRTPBaseDepayload

    struct GstRTPBaseDepayload;

### struct GstRTPBaseDepayloadClass

    struct GstRTPBaseDepayloadClass {
      GstElementClass parent_class;

      /* virtuals, inform the subclass of the caps. */
      gboolean (*set_caps) (GstRTPBaseDepayload *filter, GstCaps *caps);

      /* pure virtual function, child must use this to process incoming
       * rtp packets. If the child returns a buffer without a valid timestamp,
       * the timestamp of @in will be applied to the result buffer and the
       * buffer will be pushed. If this function returns %NULL, nothing is
       * pushed.  */
      GstBuffer * (*process) (GstRTPBaseDepayload *base, GstBuffer *in);

      /* non-pure function used to to signal the depayloader about packet loss. the
       * timestamp and duration are the estimated values of the lost packet.
       * The default implementation of this message pushes a segment update. */
      gboolean (*packet_lost) (GstRTPBaseDepayload *filter, GstEvent *event);

      /* the default implementation does the default actions for events but
       * implementation can override. */
      gboolean (*handle_event) (GstRTPBaseDepayload * filter, GstEvent * event);
    };

Base class for audio RTP payloader.

#### Members

GstElementClass `parent_class`; | the parent class |
`set_caps` () | configure the depayloader |
`process` () | process incoming rtp packets |
`packet_lost` () | signal the depayloader about packet loss |
`handle_event` () | custom event handling |

## Property Details

### The `“stats”` property

      “stats”                    GstStructure *

Various depayloader statistics retrieved atomically (and are therefore synchroized with each other). This property return a GstStructure named application/x-rtp-depayload-stats containing the following fields relating to the last processed buffer and current state of the stream being depayloaded:

clock-rate | G_TYPE_UINT, clock-rate of the stream
npt-start | G_TYPE_UINT64, time of playback start
npt-stop | G_TYPE_UINT64, time of playback stop
play-speed | G_TYPE_DOUBLE, the playback speed
play-scale | G_TYPE_DOUBLE, the playback scale
running-time-dts | G_TYPE_UINT64, the last running-time of the last DTS
running-time-pts | G_TYPE_UINT64, the last running-time of the last PTS
seqnum | G_TYPE_UINT, the last seen seqnum
timestamp | G_TYPE_UINT, the last seen RTP timestamp

Flags: Read
