[x264-devel] Multislicing support

[Etienne Bömcke]

The problem occurs when using my code, ie. the patch I emailed. I'm  
aware that the "faulty part" resides in my code, but I didn't have  
time to dive into the rate control code to understand why my code is  
responsible for this bug. I won't have time to examine your code until  
next month, but I'll definitely give a look and see wether we can  
create a common patch for both functionalities. I'll get back to you  
when I got something new.

Thanks for the link btw, I can definitely use some of the things Loren  
said there.
