Installed GStreamer version 1.4.4 then downloaded the IOS tutorials. 

Tutorial 1 compiles without any problems. The other tutorials don't.

(Xcode 6.1)
I got architectures and valid architectures set to armv7. I use base SDK
8.1.
in buildsettings i got these frameworks:
CoreGraphics.framework
Foundation.framework
UiKit.framework
GStreamer.framework

Everything compiles nicely but when linking I get:

Undefined symbols for architecture armv7:
  "_kVTCompressionPropertyKey_MaxKeyFrameInterval", referenced from:
      _gst_vtenc_set_format in
GStreamer(libgstapplemedia_a_armv7_-libgstapplemedia_la-vtenc.o)

And so on.

Thanks for helping...
