--- Comment #7 from Zeeshan Ali (Khattak) <zeeshanak at gnome.org> ---
We had a bit of discussion on this during the hackfest. Edwards was very
reluctant to drop the code in question since if a buffer gets to that point,
there is something very wrong happening upstream to the decoder and needs to be
somehow addressed. Edward suggested maybe the timestamp should in this case be
set to CLOCK_TIME_NONE.

While I, Sebastian and Olivier agree that something needs to be done, we don't
think it's the decoder's job to be fixing the timestamp and should let upstream
and downstream elements handle past timestamps. Especially since decoder in
this case is not really fixing anything.

Sebastian didn't like the idea of setting timestamp to _CLOCK_TIME_NONE since
it will break other elements downstream.

We will hopefully have another discussion today about this and have a
conclusion.
