Implemented Interfaces

GstNetTimeProvider implements GInitable.

Includes

#include <gst/net/gstnet.h>

Description

This object exposes the time of a GstClock on the network.

A GstNetTimeProvider is created with gst_net_time_provider_new() which takes a GstClock, an address and a port number as arguments.

After creating the object, a client clock such as GstNetClientClock can query the exposed clock over the network for its values.

The GstNetTimeProvider typically wraps the clock used by a GstPipeline.

Functions

gst_net_time_provider_new ()

GstNetTimeProvider *
gst_net_time_provider_new (GstClock *clock,
                           const gchar *address,
                           gint port);

Allows network clients to get the current time of clock .

Parameters

clock	a GstClock to export over the network
address	an address to bind on as a dotted quad (xxx.xxx.xxx.xxx), IPv6 address, or NULL to bind to all addresses.	[allow-none]
port	a port to bind on, or 0 to let the kernel choose

Returns

the new GstNetTimeProvider, or NULL on error.
