[x264-devel] Multislicing support

[Etienne Bömcke]

There's nothing wrong with them I guess. I'm working on an application  
that needs to be able to replace a bottom slice by a completely  
different video sequence. So I cannot have motion vectors for  
macroblocks of the upper slice linking to any macroblock of the bottom  
one, or else when switching slices artefacts would appear in the upper  
part of the sequence.
I tried to modify the x264_mb_analyse_init function. It seems that  
adjusting the values of mb.mv_min[] and mb.mv_max[] relatively to the  
slice being encoded is sufficient to obtain perfectly independent  
slices. Is there anything wrong with this method?
