Speex dev - Mar 2016 - SpeexDSP AEC into ffmpeg api

I've looked at some partial examples and read in the pdf Manual that the
Acoustic Echo Canceller can be used outside of the speex codec as a
preprocessor.  I currently have a java app that uses the ffmpeg api for
live streaming. I'm exploring integrating echo cancellation & I'd
like to
use the speexdsp AEC by mapping a javacpp library to communicate between
java & speex.  Audio quality is important, using  44.1/16 stereo.

Inserting AEC into the audio chain, it would be similar to:  Java (raw
audio bits) --> speexdsp AEC --> java --> ffmpeg --> server

My questions:

1) Is this possible/feasible?
2) would AEC return PCM audio at the same sample/bit rate at which it was
given?

Any other examples/information would be appreciated.

Cheers!
