gstnet.ptp_clock
Module for [PtpClock] class
Types 3
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 [gstnet.global.ptpInit], 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.
[gstnet.ptp_clock.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.clock.Clock.waitForSync], the GstClock::synced signal and [gst.clock.Clock.isSynced].
To gather statistics about the PTP clock synchronization, [gstnet.global.ptpStatisticsCallbackAdd] can be used. This gives the application the possibility to collect all kinds of statistics from the clock synchronization.
