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

  /* virtuals, inform the subclass of the 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);
};
