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.

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).
