Is your code based on the gstreamer_android.c that is generated by the
ndk-build magic included in the GStreamer Android binaries? Please check
if after the gst_init() call there's no other call to
gst_debug_set_default_threshold() than your own.

Also try if calling
  gst_debug_set_threshold_for_name("basesrc", GST_LEVEL_DEBUG);
makes any difference. If it does, then some code elsewhere is overriding
the default threshold you set again afterwards.

Hope this helps... apart from that your pipeline should work in theory
and we can only know why not from the debug logs.
