Also note, we have received green like on starting the Open Sourcing of 
an element we wrote two years ago. We should soon make this code public, 
in case someone wants to help porting, as this was written for 0.10. 

Why this isn't trivial work, well to be able to do that, we need the C 
code to be called back, that mean the C code need to inject java code 
that will callback C functions as needed. Please, contact me directly if 
you would need to look at this earlier. 

The plan is to port that element to 1.X, merge it back with existing 
android media helpers, removing duplicated effort, squash commits, so we 
get a nice change log and then merge in gst-plugins-bad. 

best regards, 
Nicolas
