David Schleef maintains separate repositories for several GStreamer modules with a branch where some of the signal processing code is converted to use Orc. Orc is a library and tools for generating SIMD code at runtime for simple functions.
The git repository for Orc is at git://anongit.freedesktop.org/~ds/orc
Adding the Orc remote
From the top-level directory of an existing GStreamer git clone, run:
git remote add -t orc orc git://anongit.freedesktop.org/~ds/gstreamer git fetch orc git checkout orc
And similarly in gst-plugins-base and gst-plugins-good. This creates a local branch named "orc".
These branches are rebased regularly to master.
