arghh... seems serious rrv enc is not that easy.
I'm sorry i can't give a help right now :(
Maybe of little help: here's a gcc3-linux binary
of my encoder/decoder:
http://skal.planet-d.net/coding/tmp4_i86linux_v00.gz
gcc2 version is:

At least you can generate test bitstreams
with rrv inside. => The '-red' option will
alternate P-vop/Reduced P-vop, whilst the
'-redf' one will simply force reduced
encoding for all P-VOPs.
There are also some ref bitstreams with rrv in it:
vcon-A1GE-15-ARTS-L*.bits => only I-vops (bweuarrk)
vcon-A1GE-16-ARTS-L*.bits => P-VOPs
bye,
Skal
(PS: if you experience greenish color bleeding, it's because
my f/iDct is still weak, regarding precision. Using
the reference or C implementation ['-cpu c' or '-cpu ref'
options] should solve this)
