If you want to target Android, your only choice currently is JNI. There
are GStreamer/Java bindings, but they're using JNA which is not
supported on Android: https://github.com/gstreamer-java
Those are the bindings used by processing.org for example.

They should work fine on Windows/Linux/OSX though.


Ideally there would be JNI based bindings, but those don't exist yet
and I'm not aware of anybody planning to write any.


For Eclipse, it should be able to build C code. It can for Android at
least, and there's also the CDT which allows to do plain C/C++ projects
in Eclipse. How all that works you'll have to find out yourself though,
my experience with Eclipse was many years ago :) Also nowadays Android
is using an IDE that is not based on Eclipse anymore.
