Original commit message from CVS: Finally we're on to a proper jack setup, with a specialized bin and elements that can only go in a jack bin. I had to fix the parser first to do this, but to run it, the syntax is like so: gst-launch jackbin.( filesrc ! mad ! jacksink ) But of course it's not fully functional yet. Sigh.
