Is it possible to read an absolute timestamp from stream sent trough LIVE RTSP from ONB?

Hi !

It will be necessary to know when the frame has been taken by the camera.

Please answer me !

Hey,

It is not possible to get it for each frame - we do not send out that information in Live.

But we do send RTCP message that contains frame actual timestamp - after first frame and then regularly (5 secs for i-frames, 25 secs for others) .

KR,

Svetlana

Hi Svetlana

Then is it possible with the vod from a seconds ago?

Or is there any other way I can check the time information of each frame?

Hi,

In VOD we add the 0xABAC header extension to RTP packet that contains the absolute time (NTP timestamp) for each frame.
