Description

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().

typedef struct _GstNetClientClock GstNetClientClock;

Opaque GstNetClientClock structure.


gst_net_client_clock_new ()

GstClock*           gst_net_client_clock_new            (gchar *name,
                                                         const gchar *remote_address,
                                                         gint remote_port,
                                                         GstClockTime base_time);

Create a new GstNetClientClock that will report the time provided by the GstNetClockProvider on remote_address and remote_port.

name : a name for the clock
remote_address : the address of the remote clock provider
remote_port : the port of the remote clock provider
base_time : initial time of the clock
Returns : a new GstClock that receives a time from the remote clock.
