[x264-devel] Bug (or bugs) in x264 rev 2334 OpenCL and one improvement proposal.

Well this is my bad, I wasn't expressing myself clearly. What my 
improvement proposal kept in it and what I was thinking but not 
explaining obviously is following.

To expand OpenCL and GPU usage for all possible work areas not just 
lookahead. After all OpenCL & GPU's are used for Bitcoin mining, 
password cracking, in heavy industry for making strength assessment, in 
supercomputers etc. So in sense like SMP work would be divided between 
CPU and GPU where some of the frames are processed in CPU and others in GPU.

How many actually do something else which needs GPU while encoding 
videos? For example me, video encoding is only thing I do at that 
moment, even --threads 8 I usually use tells something which is that CPU 
is 99% utilized but GPU utilization is 0%.

I know that there is limitations what GPU's can do and bandwidth between 
main memory and GPU memory slows things down etc etc. But I have wishful 
thinking that there is some operations which can be speed up with using 
GPU's other than just lookahead.

Anyway thank you about reading my rant and giving reasonable answers.
