Gstreamer SDK with hardware decoder enabling for iOS8

I was looking for a way to use hardware decoder in iOS8 in the gstreamer pipeline.

I have followed below approach:

1) Downloaded the package from http://gstreamer.freedesktop.org/data/pkg/ios/1.4.3/ and installed in the mac machine [ 10.9.4]

2) I have managed to compile sample code in Xcode, and i was using the below pipeline components for decoding RTP packets in the steaming channel.

udpsrc port=5000 ! application/x-rtp, clock-rate=90000, encoding-name=(string)H264, payload=96  ! rtph264depay ! vtdec! autovideosink sync=true

3) Unfortunately it could not find vtdec or vtdec_h264 component.

4) To check if hardware decoder plugin inside the library, xplored little bit on the installaed Package:

The below is the output of otool over Gstreamer Mach-O universal binary with 3 architectures.

GStreamer(libgstapplemedia_a_armv7_-libgstapplemedia_la-corevideobuffer.o) (architecture armv7):
GStreamer(libgstapplemedia_a_armv7_-libgstapplemedia_la-atdec.o) (architecture armv7):
GStreamer(libgstapplemedia_a_armv7_-libgstapplemedia_la-plugin.o) (architecture armv7):
GStreamer(libgstapplemedia_a_armv7_-libgstapplemedia_la-vtutil.o) (architecture armv7):
GStreamer(libgstapplemedia_a_armv7_-libgstapplemedia_la-coremediabuffer.o) (architecture armv7):
GStreamer(libgstapplemedia_a_armv7_-libgstapplemedia_la-dynapi.o) (architecture armv7):
GStreamer(libgstapplemedia_a_armv7_-libgstapplemedia_la-vtapi.o) (architecture armv7):
GStreamer(libgstapplemedia_a_armv7_-libgstapplemedia_la-iosassetsrc.o) (architecture armv7):
GStreamer(libgstapplemedia_a_armv7_-libgstapplemedia_la-avfvideosrc.o) (architecture armv7):
GStreamer(libgstapplemedia_a_armv7_-libgstapplemedia_la-avfassetsrc.o) (architecture armv7):
GStreamer(libgstapplemedia_a_armv7_-libgstapplemedia_la-coremediactx.o) (architecture armv7):

Finding:

1) The above does not entail, libgstapplemedia_la-vtdec.o

2) The Makefile.am of gst-plugins-bad-1.4.3/sys/applemedia has following code.

if HAVE_VIDEOTOOLBOX
      libgstapplemedia_la_SOURCES +=  vtenc.c  vtdec.c
      libgstapplemedia_la_LDFLAGS += -Wl,-framework -Wl,VideoToolbox
endif

QUESTION:

1) Having said the above understanding is correct [ please correct me if i am wrong], where can i get the iOS GStreamer SDK library with hardware decoding functions, which can be used in iOS8.

2) If not, Do we have to build GStreamer SDK on our own with the help of Cerbero build system?

What other quirk i need to be aware of?
