Very correct. It would be more sensible to write a decoder for  libavcodec 
before pursuing this. But this "work" on the encoder is with reference to the 
GSoC task. I'm using the RM20 reference decoder and it suits my current 
purpose. Also i think that the encoder would be tested/verified against the 
I have submitted what i hope will be the final patch for my qual task. Once 
that is done i'll have time to maybe get a basic als decoder and some code 
refactoring done. Also there is that TAK reversing thing.......... ;-)
