Gstreamer on Android(Qt C++)

[marcin at saepia.net]

First of all, try using makefile scripts that come with GStreamer (see e.g.
https://github.com/sdroege/gst-player) instead of trying to reinvent the
wheel.

Secondly, using C++ with Android may be a bad choice, it's not well
supported (http://developer.android.com/ndk/guides/cpp-support.html)
