Hmm...could we expect another version of lencod, that takes avs's as input (YV12)? That'd be cool

could we expect binaries+gui+dshow decoder?(hehe)
anyone has any screenshots(comparing this to other mpeg4's)?

BTW: If you change the fourCC of the created AVI to 'VSSH', it will play fine with VSS's latest H.264 decoder.

Also, Milan updated ffdshow yesterday, allowing it to play H.264, either from reference coder or from VSS's encoder.  Wait for a build from Athos very soon, although i already have one .

Hehe, as do I, though I did not know I did.  Thanks for the heads up  I didn't realize it was in there.  I am currently encoding X-Men 2 with VSS's encoder, the test runs I did with it were very nice so I decided to encode it @ 2 pass best quality @ 1000kbps.  It will take 25 hours to finish, I am 23 hours finished now.  The libavcodec h264 is not totally reference code just so people know; although a lot is.  If you look at the changelog you will see that there are some changes namingly a faster inloop filter for progressive i,p frames and I think faster i,p cabac from fenrir who develops x264 (a experimental h264 encoder).
EDIT: CruNcher's build that supports h264 is here http://cruncher.mufflastig.com/ffdshow/
EDIT2: ffdshow will play normal encoded vss files.

Roberto has a special builds of jm76 up again which take AVS input and outputs AVI.
http://pessoal.onda.com.br/rjamorim/lencodjm76-avi.zip
and ICL compile:
http://pessoal.onda.com.br/rjamorim/lencodjm76-avi_ICL.zip

it might have been a little bit too early to publish this as the b-frames still dont work with it, and afaik the author still works on updating the sources to make b-frames work 

but people can try the new ratecontrol now

Why early? The b-frames didn't work previously either, afaik. At least this is an update to the previous compile..

because dcoder said he still tries to fix the b-frame problem and bobololo also had it working already

yeah no problem with it of course, its great to test out avc
