Classes:

• ClientClock - ClientClock implements a custom Clock that synchronizes its time to a remote time provider such as TimeProvider.
• NtpClock
• PtpClock - GstPtpClock implements a PTP (IEEE1588:2008 ) ordinary clock in slave-only mode, that allows a GStreamer pipeline to synchronize to a PTP network clock in some specific domain.
• TimePacket - Various functions for receiving, sending an serializing TimePacket structures.
• TimeProvider - This object exposes the time of a Clock on the network.

Structs:

• AddressMeta - AddressMeta can be used to store a network address (a SocketAddress) in a Buffer so that it network elements can track the to and from address of the buffer.
• ControlMessageMeta - ControlMessageMeta can be used to store control messages (ancillary data) which was received with or is to be sent alongside the buffer data.

Constants:

• public const uint64 PTP_CLOCK_ID_NONE
  PTP clock identification that can be passed to ptp_init to automatically select one based on the MAC address of interfaces
• public const string PTP_STATISTICS_BEST_MASTER_CLOCK_SELECTED
• public const string PTP_STATISTICS_NEW_DOMAIN_FOUND
• public const string PTP_STATISTICS_PATH_DELAY_MEASURED
• public const string PTP_STATISTICS_TIME_UPDATED

Delegates:

• public delegate bool PtpStatisticsCallback (uint8 domain, Structure stats)
  The statistics can be the following structures:

Methods:

• public Type address_meta_api_get_type ()
• public unowned MetaInfo? address_meta_get_info ()
• public unowned AddressMeta? buffer_add_net_address_meta (Buffer buffer, SocketAddress addr)
  Attaches addr as metadata in a AddressMeta to buffer.
• public unowned ControlMessageMeta? buffer_add_net_control_message_meta (Buffer buffer, SocketControlMessage message)
  Attaches message as metadata in a ControlMessageMeta to buffer.
• public unowned AddressMeta? buffer_get_net_address_meta (Buffer buffer)

• public void ptp_deinit ()
  Deinitialize the GStreamer PTP subsystem and stop the PTP clock.
• public bool ptp_init (uint64 clock_id, string[]? interfaces)
  Initialize the GStreamer PTP subsystem and create a PTP ordinary clock in slave-only mode for all domains on the given interfaces with the given clock_id.
• public bool ptp_is_initialized ()
  Check if the GStreamer PTP clock subsystem is initialized.
• public bool ptp_is_supported ()
  Check if PTP clocks are generally supported on this system, and if previous initializations did not fail.
• public ulong ptp_statistics_callback_add (owned PtpStatisticsCallback callback)
  Installs a new statistics callback for gathering PTP statistics.
• public void ptp_statistics_callback_remove (ulong id)
  Removes a PTP statistics callback that was previously added with ptp_statistics_callback_add.
• public TimePacket time_packet_receive (Socket socket, out SocketAddress src_address) throws Error
  Receives a TimePacket over a socket.
• public bool utils_set_socket_tos (Socket socket, int qos_dscp)
  Configures IP_TOS value of socket, i.
