[x264-devel] encoding with lots of small slices

[Michael Roitzsch]

Hi x264 team,

for a research project I am trying to create H.264 files with lots of  
small slices. I realise that the code of x264 limits the amount of  
slices. Maybe you can give me some starters, which assumptions would  
break if this limitation is removed. I already tried to encode videos  
with 128 slices and more, but as soon as slices do not start with the  
first macroblock of a macroblock row, but somewhere in the middle of  
a row, the video looks wrong when decoded with FFmpeg's H.264  
decoder. This could of course be a bug in FFmpeg, but I guess it's  
more likely to be something in x264 that breaks when I remove the  
slice limitations. I would appreciate any ideas on this.

Michael
