README 

Note that this code was unfinished at the time I stopped working on it, and required
patches to Gstreamer to get resonable results,
http://gstreamer-devel.966125.n4.nabble.com/Talking-clock-timestamp-problem-td4668337.html
(The code in that area of Gstreamer has since changed though.)

Install and run on Ubuntu 14.04
-------------------------------

Install dependancies:

  sudo aptitude install ruby2.0-dev ruby-gir-ffi gir1.2-gst-plugins-base-1.0


Run:

  ruby2.0 main.rb



Listen to the resulting stream:

Includes a waveform view and timestamps since playback started (not AES67-style though),
