Struct gstreamer_net::PtpClock

pub struct 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.

The PTP subsystem can be initialized with gst_ptp_init, which then starts a helper process to do the actual communication via the PTP ports. This is required as PTP listens on ports < 1024 and thus requires special privileges. Once this helper process is started, the main process will synchronize to all PTP domains that are detected on the selected interfaces.

PtpClock::new then allows to create a GstClock that provides the PTP time from a master clock inside a specific PTP domain. This clock will only return valid timestamps once the timestamps in the PTP domain are known. To check this, you can use gst::ClockExt::wait_for_sync, the GstClock::synced signal and gst::ClockExt::is_synced.

To gather statistics about the PTP clock synchronization, gst_ptp_statistics_callback_add can be used. This gives the application the possibility to collect all kinds of statistics from the clock synchronization.

impl PtpClock

pub fn new<'a, P: Into<Option<&'a str>>>(     name: P,     remote_address: &str,     remote_port: i32,     base_time: ClockTime ) -> PtpClock

Creates a new PTP clock instance that exports the PTP time of the master clock in domain. This clock can be slaved to other clocks as needed.

If gst_ptp_init was not called before, this will call gst_ptp_init with default parameters.

This clock only returns valid timestamps after it received the first times from the PTP master clock on the network. Once this happens the GstPtpClock::internal-clock property will become non-NULL. You can check this with gst::ClockExt::wait_for_sync, the GstClock::synced signal and gst::ClockExt::is_synced.
