[Live-devel] Absolute seekStream - problem with timestamps

[Francisco Feijoo]

Hello Ross,

You are right, I was setting fPresentationTime incorrectly in the server
end for 'trick play'. I was trying to set it as the "actual frame time"
(when the frame was recorded), which as you said is wrong.

How could I know in the client end what is the actual frame time? Is there
any standard way of doing this?

This is quite close to the thread opened today by Michael S. Juul
"Presentation time when streaming video recording from surveillance
cameras" but in my case I control both sides (client and server) which use
live555.

Thanks.
