Zero copying from shmsrc to shmsink possible

[Peter Maersk-Moller]

Hi.

Assuming you have a pipeline ending in a shmsink like this

  gst-launch-1.0 ...something ! shmsink socket-path=/tmp/sockA
wait-for-connnection=0

And then you in a second pipeline have something like this

  gst-launch-1.0 shmsrc socket-path=/tmp/sockA ! queue ! shmsink
socket-path=/tmp/sockB wait-for-connnection=0

Is there then a way that the second shmsink (sockB) can reuse the the
shmarea allocated by the shmsink sockA so this can work with zero copying ?
Or will there always have to be a buffer copying from shmsrc sockA to
shmsink sockB in the above example?
