The size of the packets sent between network clocks.
#GstNetAddress can be used to store a network address. #GstNetAddressMeta can
be used to store a network address in a #GstBuffer so that it network
elements can track the to and from address of the buffer.

This object implements a custom #GstClock that synchronizes its time
to a remote time provider such as #GstNetTimeProvider.
A new clock is created with gst_net_client_clock_new() which takes the
address and port of the remote time provider along with a name and
an initial time.
This clock will poll the time provider and will update its calibration
parameters based on the local and remote observations.
Various parameters of the clock can be configured with the parent #GstClock
"timeout", "window-size" and "window-threshold" object properties.
A #GstNetClientClock is typically set on a #GstPipeline with
gst_pipeline_use_clock().

Creates a new #GstNetTimePacket from a buffer received over the network. The
caller is responsible for ensuring that @buffer is at least
#GST_NET_TIME_PACKET_SIZE bytes long.
If @buffer is #NULL, the local and remote times will be set to

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.
