Android.mk


LOCAL_PATH := $(call my-dir)

# Edit this line
GSTREAMER_ROOT_ANDROID := C:\Users\TR\Desktop\gstreamer-1.0-android-arm-release-1.4.4

The problem here is the sprop-parameter-sets caps field. Such fields
often fail to be parsed in gst_parse_launch() unfortunately.

Try setting the caps explicitly on the udpsrc element via
g_object_set() and gst_caps_from_string() instead for the time being.
