wondering if one could add a name= teesink somewhere that can be updated
t1. ! queue ! volume volume=1 ! name=teesink0 i.src1 \
and update teesink0 to a different interleave src?
Currently I am able to update volume etc using named pads, but it would be
great if the channel mapping could also be updated dynamically. My limited
understanding says this isn't possible using gst_parse_launch()?
