Any integer lossless encoder to fit "iRockbox"?, A suitable lossless encoder for Rockbox?

As some may know the Rockbox iRiverport for iHP1xx is on his way thanks to LinusM releasing his precious "bootloader"...

Actually the team is concentrating his work on the AUDIO part... The great priority of course is decoding (especially MP3 even if a lot of audio codecs are in the TODOlist!)

Anyway the team have made some searchs for encoding part and they complaining they don't find much things that seems suitable for the iRiverport since they need INTEGER encoders that won't overdrive the iHP processor...

So i've asked on the HA "rockbox iRiverport" thread for LOSSY integer encoder with Open-source license of course (check HERE)...

As there is a lossless section i make this thread to ask the same thing but for an interger lossless open source encoder!

I will be very kind of you to put all information you know about such an encoder! smile.gif

Actually there is a really fast free (non-commercial) mp3 encoder. I tested it on Intel XScale PXA255 @400MHz, 100MHz 32bit SDRAM. This processor is quite common in PDA's, and has no floating point unit! It took 40sec to compress 60sec audio, so it works real time.
Input: 44100Hz 16bit stereo
Output: 128kbps 44.1KHz mp3
The encoder is the sample mp3 encoder for the Intel Performance Primitives (IPP) library. It can be freely downloaded from intel's website!
