C, as there is not complete binding for Java.

You'd still need to build GStreamer for each platform. Java is portable
without recompiling, GStreamer is portable, but require building for
each platforms. Note that you could do the core of your work in C and
provide a thin layer (implementing JNI bindings) for the UI to be in
Java (or C#).

You need JNI, but yes, as I just mention.

I would not look for bindings, but do the core multimedia work in C and
then provide a JNI layer for Java which make sense and is high level
enough.

I don't think this has ever been done since 1.0.

Java will add a certain overhead (even though it's better then Python
for sure). Other then that, the high level API approach has worked well
for me in various Android projects. On Windows we have most often
provided C# binding of our high level library (the library implementing
our use case using GStreamer).
