Well reference source code for MPEG-4 is available, and shouldnt be a huge task to port ... of course the licensing fees are once
again up in the air (sigh ... patents promote innovation my ass) but the initial now retracted terms of $.25 per unit and $.00033
per minute of video seem reasonable for your applications.

Im not a fan of 3D wavelets at all ... just wanted to indicate that multiscale motion compensation ignores the fact that motion
boundaries are only really present at the finest scale, compensating a wavelet who's footprint crosses the motion boundary seems
wrong. Even ignoring that wavelets are not translation invariant.
