hi hi,

sorry if this is a bit offtopic. Most of you may already know, that I am working
on a gstreamer based music tracker on http://www.buzztard.org.

Currently I am thinking about how to implement mute/solo/bypass function for the
 machine-network.  The problem is that I don't know enough about the scheduler.

There is one optimization the original buzz-software seems to make. When a src
machine produced a buffer of silence, it tagges the buffer as such. The
scheduler in buzz then just bypasses all following machines (to save cpu
cycles). Any idea how such a thing can be done in gst?

The next thing is, when I temporarily unlink a part from the nextwork and
therwith a chain of elements is not connected to a sink, do our schedulers (e.g.
opt) skip them then? Means when I mute a filter, I would like to unlink its
previous elements and set its output to silence.
