Hi,

I have a fresh build of FFMPEG and x264 that I built today. I have noticed 2 things (I don't think anything changed in my most recent build - I just wanted to mention that I am on the most recent code).

I am doing 2 pass encoding on a 2 core machine.

1) It seems that the first pass of my encode only uses 1 core regardless of what I set -threads to. Is this an FFMPEG issue? x264 issue? An issue with a setting I am using?

2) On the 2nd pass, in order to fully load the machine I need to use 4 threads on a 2 core machine. What is the "optimal" number of threads to use for encoding based on the number of cores in the machine?

Thanks
