androidvideo ndk-build fails

[mdrio]

Hi, I would try androivideo libs for streaming embedded cameras but I'm to sure which is the right way to use it.
I run ndk-build in openwebrtc-gst-plugins/sys/androidvideo/video-source/jni/ setting GLIB_GST_PATH in Android.mk to the dir where I extracted openwebrtc-android-armv7-0.3.0.zip.
This is the message from ndk-build: http://pastebin.com/0ZycmwY2

Any suggestions?
Thanks.
