u_int32 get_lower_16bits (  u_int32  x  )  [inline]

u_int32 get_middle_32bits (  u_int32  x, u_int32  y )  [inline]

u_int32 get_upper_16bits (  u_int32  x  )  [inline]

ntp64 getntptime (   )

Get the ntp time (out of gettimeofday). Returns: A time in NTP format

u_int32 time2ts (  const ntp64 &  time, const ntp64 &  time_first, u_int32  freq )

Transform a ntp64 to an RTP timestamp. RTP timestamps are integer values that are strictly increasing in a payload-dependant frequency. Timestamps start at 0 (beginning of transmission), e.g. no random offset is calculated. Parameters: time  The NTP time to be transformed time_first  The reference time, in this case the start of the RTP transmission (which is RPT timestamp 0 itself) freq  The payload-dependent timestamp frequency, e.g. given in Hz. Returns: The RTP timestamp for time.
