In theory that would be possible, but it's completely untested and will
probably not work without further changes. And most importantly, you
will need an element in front of your sink that can actually be pulled
from.

There were some experiments with that in 0.10 times and audio sinks,
but not much came out of that because IIRC the advantages were rather
minimal and did not warrant the added complexity.


Why would you like to have a pull mode video sink?
