playbin2 with MJPEG streams over http: long delay before playback starts, and buffering delays on each frame

I managed to find the multipartdemux element, but the single-stream
property doesn't exist:

If I take out the if( exists...) check and simply try to set
the property:

(<unknown>:26920): GLib-GObject-WARNING **: g_object_set_valist: object
class `GstMultipartDemux' has no property named `single-stream'

I'm using GStreamer version 0.10.35, and gst-plugins-good-0.10.30.  What
version was the single-stream property added in?

The property is explicitly set on line 514. It's rather ugly, but it does the trick.
