      All Methods Instance Methods Abstract Methods 
      Modifier and Type Method Description
      long getLocalTime​(long ssrc, long rtpTime)
      Tries to find the local time (as returned by System.currentTimeMillis()) that corresponds to the RTP timestamp rtpTime for the SSRC ssrc.
      void mapLocalToNtp​(long ssrc, long localTime, double ntpTime)
      Notifies this Synchronizer that the local timestamp localTime corresponds to the NTP timestamp ntpTime (for SSRC ssrc).
      void mapRtpToNtp​(long ssrc, long rtpTime, double ntpTime)
      Notifies this Synchronizer that the RTP timestamp rtpTime (for SSRC ssrc) corresponds to the NTP timestamp ntpTime.
      void setEndpoint​(long ssrc, String endpointId)
      Sets the endpoint identifier for a specific SSRC.
      void setRtpClockRate​(long ssrc, long clockRate)
      Sets the clock rate of the RTP clock for a specific SSRC.

    • Method Detail

      • setRtpClockRate

        void setRtpClockRate​(long ssrc,
                     long clockRate)
        Sets the clock rate of the RTP clock for a specific SSRC.
        Parameters:
        ssrc - the SSRC for which to set the RTP clock rate.
        clockRate - the clock rate.

      • setEndpoint

        void setEndpoint​(long ssrc,
                 String endpointId)
        Sets the endpoint identifier for a specific SSRC.
        Parameters:
        ssrc - the SSRC for which to set the endpoint identifier.
        endpointId - the endpoint identifier to set.

      • mapRtpToNtp

        void mapRtpToNtp​(long ssrc,
                 long rtpTime,
                 double ntpTime)
        Notifies this Synchronizer that the RTP timestamp rtpTime (for SSRC ssrc) corresponds to the NTP timestamp ntpTime.
        Parameters:
        ssrc - the SSRC.
        rtpTime - the RTP timestamp which corresponds to ntpTime.
        ntpTime - the NTP timestamp which corresponds to rtpTime.

      • mapLocalToNtp

        void mapLocalToNtp​(long ssrc,
                   long localTime,
                   double ntpTime)
        Notifies this Synchronizer that the local timestamp localTime corresponds to the NTP timestamp ntpTime (for SSRC ssrc).
        Parameters:
        ssrc - the SSRC.
        localTime - the local timestamp which corresponds to ntpTime.
        ntpTime - the NTP timestamp which corresponds to localTime.

      • getLocalTime

        long getLocalTime​(long ssrc,
                  long rtpTime)
        Tries to find the local time (as returned by System.currentTimeMillis()) that corresponds to the RTP timestamp rtpTime for the SSRC ssrc. Returns -1 if the local time cannot be found (for example because not enough information for the SSRC has been previously provided to the Synchronizer).
        Parameters:
        ssrc - the SSRC with which rtpTime is associated.
        rtpTime - the RTP timestamp
        Returns:
        the local time corresponding to rtpTime for SSRC ssrc if it can be calculated, and -1 otherwise.
