GStreamer Tutorial udpsink created using instructions posted on Stack Overflow by Eduardo Fernando. VariableGSTREAMER_ROOT_ANDROID must be defined in/etc/profile or/home/USERNAME/.profile and show to a path where you have extracted GStreamer Android binaries, for example:export GSTREAMER_ROOT_ANDROID=/home/USERNAME/gstreamer-1.0-android-universal-1.14.2If you're having trouble building the project, download and unzip revision 10e of the NDK, set path pointing to it in your project's settings and copy filesource.properties from the up-to-date NDK folder to folder containing the 10e version.The app streams phone's main camera feed to a given IP address using openh264enc, default receiver's port number is 5000.
