I have an IP camera that is located in a different country (with a different time zone) and that has it’s own date-time values applied, (for example:~2012-04-16 11:30:00) then the one my PC is located at. (so my PC’s time for example is ~2012-14-16 06:10:00)

My purpose:
When streaming, i need to get this date-time value that is set in camera (“11:30:00”)
(I’m not interested in a current local time of my PC).

  • Is there any way to calculate camera’s date-time value from RTP’s timestamp?
  • Is there any other approach?

I’m using a Live555 library, and for frame’s date-time retrieval I was using a “presentation time” value, but this gives me a local time of my PC (not the time that is set in my camera)

So I’m stuck here..

    Read the RFC on RTP packet layout

    Note that the Timestamp is in the RTP packet at 0x32. This is the timestamp from the camera that encoded the stream.

    For a CPP implementation, processing RTP packet and headers including the timestamp , see the link.

    Java implementation of RTP packet handler here
