UDP sink Gstreamer + Android

[Dmitri Afanasjev]

Hello again,

I'm stuck with implementing GstVideoOverlay using my pipline..
Is it right doc page to learn how to implement current imterface?

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstvideooverlay.html#gst-video-overlay-prepare-window-handle

Regards, Dmitri
