Static methods:

• public static HeaderExtension? create_from_uri (string uri)

Creation methods:

• protected HeaderExtension ()

Methods:

• public HeaderExtensionDirection get_direction ()
  Retrieve the direction
• public uint get_id ()
• public virtual size_t get_max_size (Buffer input_meta)
  This is used to know how much data a certain header extension will need for both allocating the resulting data, and deciding how much payload data can be generated.
• public string get_sdp_caps_field_name ()
• public virtual HeaderExtensionFlags get_supported_flags ()
• public unowned string get_uri ()
• public virtual bool read (HeaderExtensionFlags read_flags, uint8[] data, Buffer buffer)
  Read the RTP header extension from data.
• public virtual bool set_attributes (HeaderExtensionDirection direction, string attributes)
• public bool set_attributes_from_caps (Caps caps)
  set_id must have been called with a valid extension id that is contained in these caps.
• public virtual bool set_caps_from_attributes (Caps caps)
  set_id must have been called with a valid extension id that is contained in these caps.
• public bool set_caps_from_attributes_helper (Caps caps, string attributes)
  Helper implementation for GstRTPExtensionClass::set_caps_from_attributes that sets the this uri on caps with the specified extension id as required for sdp Caps.
• public void set_direction (HeaderExtensionDirection direction)
  Set the direction that this header extension should be used in.
• public void set_id (uint ext_id)
  sets the RTP extension id on this
• public virtual bool set_non_rtp_sink_caps (Caps caps)
  Passes RTP payloader's sink (i.e. not payloaded) caps to the header extension.
• public class void set_uri (string uri)
  Set the URI for this RTP header extension implementation.
• public void set_wants_update_non_rtp_src_caps (bool state)
  Call this function in a subclass from GstRTPHeaderExtensionClass::read to tell the depayloader whether the data just parsed from RTP packet require updating its src (non-RTP) caps.
• public virtual bool update_non_rtp_src_caps (Caps caps)
  Updates depayloader src caps based on the information received in RTP header.
• public bool wants_update_non_rtp_src_caps ()
  Call this function after read to check if the depayloader's src caps need updating with data received in the last RTP packet.
• public virtual ssize_t write (Buffer input_meta, HeaderExtensionFlags write_flags, Buffer output, uint8[] data)
  Writes the RTP header extension to data using information available from the input_meta.
