AW: [Live-devel] Sync problems with dvb-t streams

[Michael Golebski]

Hi Ross !
First of all, we are not a company but only a group of students working on a
project about streaming in wireless networks.

Can we simply take the timestamp from the PES (looks different from the
PresentationTime which is only the unixtime of the system) and use it as the
PresentationTime or do we have to recalculate it? 
I think it's not trivial at all because we only have a buffered source and
not a framed source and so the allocation of a PTS to the according data
might be a problem.

Just to be sure - the internal timestamps of an ES are not for syncing audio
and video, right?
