I posted yesterday on FGO vs PsyRDO topic VFR Maniac experemental x264 Build http://www.esnips.com/web/VFRmaniac-Softwares, which support slice encoding, patch is done by Mojtaba Hosseini/Etienne Bomcke, archive aslo contain diff.

There are tree switches --max-slicesize, --mb-slicesize, --no-mv-inter-slices, and i can't figure how to set for example 4 slices? and how this affect on quality.

Anybody tryed

It goes by number of macroblocks using --mb-slicesize I believe.

So if your image is 1280x720.
It should be 80x45 macroblocks.
Multiply that, 3600 macroblocks total. Divide by 4, number to set --mb-slicesize too. (it counts across, then next row down, etc..)

All of this is "I THINK it's right". Cause I tried fuxing with the patch, never got it to work right with threading though.
If it's wrong, i'm close (I think) just screw around with it. Use some analyzer to see if it's really slicing the video.
