Struct gstreamer_net::NetClientClock
source · pub struct NetClientClock { /* private fields */ }
Expand description
NetClientClock
implements a custom gst::Clock
that synchronizes its time
to a remote time provider such as NetTimeProvider
. NtpClock
implements a gst::Clock
that synchronizes its time to a remote NTPv4 server.
A new clock is created with new()
or
NtpClock::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.
The “round-trip” property limits the maximum round trip packets can take.
Various parameters of the clock can be configured with the parent gst::Clock
“timeout”, “window-size” and “window-threshold” object properties.
A NetClientClock
and NtpClock
is typically set on a gst::Pipeline
with
[PipelineExtManual::use_clock()
][crate::gst::prelude::PipelineExtManual::use_clock()].
If you set a gst::Bus
on the clock via the “bus” object property, it will
send GST_MESSAGE_ELEMENT
messages with an attached gst::Structure
containing
statistics about clock accuracy and network traffic.

§parent
The parent of the object. Please note, that when changing the ‘parent’
property, we don’t emit [notify
][struct@crate::glib::Object#notify] and deep-notify
signals due to locking issues. In some cases one can use
GstBin::element-added
or GstBin::element-removed
signals on the parent to
achieve a similar effect.
