It wasn't released yet. The release was planned at last monday, but
it was delayed many times. Latest planned release time is tomorrow.

It's a native linux dynamic library, containing code for different CPU's
and uses CPU autodetection.
I got the beta from Eugene for testing. It isn't public yet (AFAIK).

They can't (or don't want?) release source, only in binary form.
They said that it's because of licensing problem, divx 3.11 decoding
is illegal this way, and maybe they are using some code or tables from
the win32 DLL...
I (and also Eugene) hope that it will change to LGPL soon, and they
will release sources.

The API is 95% compatible with opendivx-CVS, but has some new options,
like DivX ;-) 3.11 decoding, and memory allocation changed a bit.

Btw it's quite buggy, crashes playing files encoded with opendivx 0.47, and
crashes for everything if postprocessing is enabled.

The encoder engine is based on Eugene's "Sparky" codec. I haven't tested it
yet but seems to be nice, at least has many tuneable parameters :)
(even the behaviour of the quantization and bitrate control is 
tunable with many parameters)
