ptp: Initial implementation of a PTP clock 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. gst_ptp_clock_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, the GstPtpClock::internal-clock property and the related notify::clock signal can be used. Once the internal clock is not NULL, the PTP domain's time is known. Alternatively you can wait for this with gst_ptp_clock_wait_ready(). 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. https://bugzilla.gnome.org/show_bug.cgi?id=749391 2015-05-14 10:18:25 +00:00			`#ifndef __GST_PTP_PRIVATE_H__`
