Get NTP Time from IP Camera Axis

Hi,

I would like to get the NTP Time sent by IP Camera inside Sending Report (RTCP).

Wireshark traces show NTP Time in RTCP sent every 4s by the camera to wowza

  • MSW : 366341728 (0xda5b4fc9)

  • LSW : 3563860783 (0xd46c332f)

MSW and LSW as NTP Timestamp : Feb 2, 2016 15:54:49.829775000 UTC

In a Wowza modula We print the following variables for each packet received :

If AVSyncMethod = sendreport, we get 0 and after the firt SR received :

thisPacket.getAbsTimecode = 410515546

stream.getVideoTC = 410515546

If AVSyncMethod = systemclock wet get server unix timestamp

What exactly are thisPacket.getAbsTimecode() and stream.getVideoTC() values when AVSyncMethod = sendreport ? Can we link the result with camera NTP time ?

Is it a class we can extend to analyse each SR RTCP packet and get MSW and LSW fields ?

Many thanks for your help.

David

No answer ?

Is anyone knows what thisPacket.getAbsTimecode() value is ?
