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.
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
.

Queries whether GstRTPSourceMeta will be added to depayloaded buffers.

void gst_rtp_base_depayload_set_source_info_enabled (GstRTPBaseDepayload *depayload

Enable or disable adding GstRTPSourceMeta to depayloaded buffers.

Same as the process virtual function, but slightly more
efficient, since it is passed the rtp buffer structure that has already
been mapped (with GST_MAP_READ) by the base class and thus does not have
to be mapped again by the subclass. Can be used by the subclass to process
incoming rtp packets. If the subclass returns a buffer without a valid
timestamp, the timestamp of the input buffer will be applied to the result
buffer and the output buffer will be pushed out. If this function returns

property “source-info” gboolean
Add RTP source information found in RTP header as meta to output buffer.

“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
