Hi,
I am trying to work out how to get absolute time-stamps from an incoming
MPEG transport stream.
The basics seem to be that we get a presentation time-stamp via
buffer->get_pts(). This is relative to the program clock reference PCR which is
dictated by one of the elementary streams - typically the video. How do I get
that base time out of gstreamer?
I note that if I use a tsparse element it can decode TOT and TDT sections for
DVB inputs. However, I also notice that one of my inputs is a TSIP input which
does not include these sections.
How can I tell if an absolute time reference is available and when it is what
is the epoch? Is it the standard unix epoch 1970-01-01T00:00:00Z?
Regards,
Bruce.
