I\'m in a quandary. I\'m following the following tutorial (specifically, 6.4.2)

In my case the answer was to add the location of the gstreamer binaries to my PATH and my PYTHONPATH (not sure if the second is required)
C:\Program Files (x86)\OSSBuild\GStreamer\v0.10.7\bin
is the location on my machine.
