GST_BASE_RTP_DEPAYLOAD_SINKPAD()

#define GST_BASE_RTP_DEPAYLOAD_SINKPAD(depayload) (GST_BASE_RTP_DEPAYLOAD (depayload)->sinkpad)

GST_BASE_RTP_DEPAYLOAD_SRCPAD()

#define GST_BASE_RTP_DEPAYLOAD_SRCPAD(depayload)  (GST_BASE_RTP_DEPAYLOAD (depayload)->srcpad)

gst_base_rtp_depayload_push ()

GstFlowReturn       gst_base_rtp_depayload_push         (GstBaseRTPDepayload *filter,
                                                         GstBuffer *out_buf);

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

Unlike gst_base_rtp_depayload_push_ts(), this function will not apply any timestamp on the outgoing buffer. Subclasses should therefore timestamp outgoing buffers themselves.

gst_base_rtp_depayload_push_ts ()

GstFlowReturn       gst_base_rtp_depayload_push_ts      (GstBaseRTPDepayload *filter,
                                                         guint32 timestamp,
                                                         GstBuffer *out_buf);

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

Unlike gst_base_rtp_depayload_push(), this function will by default apply the last incomming timestamp on the outgoing buffer when it didn't have a timestamp already. The set_get_timestamp vmethod can be overwritten to change this behaviour (and take, for example, timestamp into account).

gst_base_rtp_depayload_push_list ()

GstFlowReturn       gst_base_rtp_depayload_push_list    (GstBaseRTPDepayload *filter,
                                                         GstBufferList *out_list);

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

The "queue-delay" property

  "queue-delay"              guint                 : Read / Write

Amount of ms to queue/buffer, deprecated.

Default value: 0
