GStreamer multi pipeline time sync

[Tim Müller]

Hi Peter,

I have an example for save-to-file-with-backlog here:

https://people.freedesktop.org/~tpm/code/test-backlog-recording-h264.c

or (rtp variant):

https://people.freedesktop.org/~tpm/code/test-backlog-recording-h264-rtp.c

for what it's worth.

And audiomixer element can produce silence samples if it operates in
live mode, which will happen if the upstream source is a live/capture
source or you force it into live mode with a dummy audiotestsrc is-
live=true branch.

  Alternatively  .. ! interaudiosink   interaudiosrc ! ...

Cheers
 Tim
