I have gstreamer installed. I get this SEGV when I run it.

I have tried this on Ubuntu 12.10 and 13.04 fresh installations.

The steps to reproduce are:

  1. Clone the gstreamer, gst-plugins-base, gst-plugins-good, gst-plugins-ugly from gstreamer's git at freedesktop at ~/gst/. All these are in master branch
for module in gstreamer gst-plugins-base gst-plugins-good gst-plugins-ugly; do
   git clone git://anongit.freedesktop.org/git/gstreamer/$module ;
done
  1. I clone gst-plugins-bad and gst-switch from https://github.com/duzy/ into ~/gst/. I checkout gst-plugins-bad to speakertrack_new and gst-switch into speaker-tracking branch.
  2. I go into ~/gst/gst-switch and do ./scripts/stage.
  3. After the above step is over, I go into ~/gst/stage/bin/ and execute ./gst-switch-srv.

Try checking out these references:

gstreamer 6c11da18a58cbf970770f8697c803a2d4c0cbb74
gst-plugins-base a8df760c960bf22d997d0b13f93f15da99d9ce90
gst-plugins-good d14d4c436ce8d946997c927c61a4da9001cff936
gst-plugins-ugly 68985ba2abda2775675de97a5ca6cb2e3e4c4682

There might be revision mismatched. I can't find any clues from the "bt"
you listed, that seems from faac plugin.
