As per my undestanding, the decoder in this pipeline doesn't need to join the
session from vpp but just share it, does it?

But for vpps in this pipeline, seems it should create its own session
seperately because there is an element that should be using system memory while
the patch doesn't do that.

Can we think about this kind of complexed pipelines later or we should handle
this in this thread too?
