This problem also causes Unity 8 on desktop to hang during startup. A key clue:
$ grep "Initializing GStreamer Core" unity8.log 0:00:00.000070748 2537 0x1169400 INFO GST_INIT gst.c:499:init_pre: Initializing GStreamer Core Library version 1.4.0 0:00:00.000063448 2537 0x1169400 INFO GST_INIT gst.c:613:init_pre: Initializing GStreamer Core Library version 0.10.36
I don't think it's a good idea to use both versions of GStreamer in the same binary, hilarity ensues.
