Properties:

• public bool auto_header_extension { get; set; }
  If enabled, the payloader will automatically try to enable all the RTP header extensions provided in the src caps, saving the application the need to handle these extensions manually using the GstRTPBasePayload::request-extension: signal.
• public int64 max_ptime { get; set; }
• public int64 min_ptime { get; set; }
  Minimum duration of the packet data in ns (can't go above MTU)
• public uint mtu { get; set; }
• public bool onvif_no_rate_control { get; set; }
  Make the payloader timestamp packets according to the Rate-Control=no behaviour specified in the ONVIF replay spec.
• public bool perfect_rtptime { get; set; }
  Try to use the offset fields to generate perfect RTP timestamps.
• public uint pt { get; set; }
• public int64 ptime_multiple { get; set; }
  Force buffers to be multiples of this duration in ns (0 disables)
• public bool scale_rtptime { get; set; }
  Make the RTP packets' timestamps be scaled with the segment's rate (corresponding to RTSP speed parameter).
• public uint seqnum { get; }
• public int seqnum_offset { get; set; }
• public bool source_info { get; set; }
  Enable writing the CSRC field in allocated RTP header based on RTP source information found in the input buffer's SourceMeta.
• public uint ssrc { get; set; }
• public Structure stats { owned get; }
  Various payloader statistics retrieved atomically (and are therefore synchroized with each other), these can be used e.g. to generate an RTP-Info header.
• public uint timestamp { get; }
• public uint timestamp_offset { get; set; }

Creation methods:

• protected BasePayload ()

Methods:

• public Buffer allocate_output_buffer (uint payload_len, uint8 pad_len, uint8 csrc_count)
  Allocate a new Buffer with enough data to hold an RTP packet with minimum csrc_count CSRCs, a payload length of payload_len and padding of pad_len.
• public virtual Caps get_caps (Pad pad, Caps filter)
• public uint get_source_count (Buffer buffer)
  Count the total number of RTP sources found in the meta of buffer , which will be automically added by allocate_output_buffer.
• public virtual FlowReturn handle_buffer (Buffer buffer)
• public bool is_filled (uint size, ClockTime duration)
  Check if the packet with size and duration would exceed the configured maximum size.
• public bool is_source_info_enabled ()
  Queries whether the payloader will add contributing sources (CSRCs) to the RTP header from SourceMeta.
• public FlowReturn push (owned Buffer buffer)
  Push buffer to the peer element of the payloader.
• public FlowReturn push_list (owned BufferList list)
  Push list to the peer element of the payloader.
• public virtual bool query (Pad pad, Query query)
• public virtual bool set_caps (Caps caps)
• public void set_options (string media, bool @dynamic, string encoding_name, uint32 clock_rate)
  Set the rtp options of the payloader.
• public bool set_outcaps_structure (Structure? s)
  Configure the output caps with the optional fields.
• public void set_source_info_enabled (bool enable)
  Enable or disable adding contributing sources to RTP packets from SourceMeta.
• public virtual bool sink_event (Event event)
• public virtual bool src_event (Event event)

Signals:

• public signal void add_extension (owned HeaderExtension ext)
  Add ext as an extension for writing part of an RTP header extension onto outgoing RTP packets.
• public signal void clear_extensions ()
  Clear all RTP header extensions used by this payloader.
• public signal HeaderExtension? request_extension (uint ext_id, string ext_uri)
  The returned ext must be configured with the correct ext_id and with the necessary attributes as required by the extension implementation.
