MPEG TS PCR and PTS

[Adams, Bruce (KMLWG)]

That's not correct according to the DVB standard (see http://www.etsi.org/deliver/etsi_en/300400_300499/300468/01.15.01_60/en_300468v011501p.pdf).
Both the TDT (mandatory) and TOT (optional) contain both and time and date stamps.

The issue on the gstreamer side is that the message comes on the bus (MPEG section -> TDT) and the PTS comes via the buffers. How do I associate these?

Perhaps I need an event via a pad rather than a message on the bus external the pipeline?

Perhaps what I want is a clock? As in:
https://gstreamer.freedesktop.org/documentation/application-development/advanced/clocks.html

I don't actually have any elements providing clock information in my pipeline at present. I would like a clock based on the absolute time from the TDT. 
Similarly a clock based on absolute time-stamps from RTP could also be useful.

TDT does not have have timestamp information. TDT is date information only.
Timestamps are entirely derived from PTS and PCR(PCR only in live cases for
clock skew compensation)
