Edit Question
Title
Body
I need to maximize speed while converting videos using FFmpeg to h264 Any input format of source videos User's machine can have any number of cores Power and memory consumption are non-issues Of course, there are a whole bunch of options that can be tweaked but this question is particularly about choosing the best -thread <count> option. I am trying to find an ideal thread count as a function of no. of cores input video format h264-friendly values maybe? anything else missed above? I am aware the default -thread 0 follows one-thread-per-core approach which is supposed to be optimal. But I am not sure if this is time or space-optimized. Also, on certain testcases, I've seen more threads (say 4 threads on my dual core test machine) finishes quicker than the default. Any other direction, say configure options w.r.t. threads, worth pursuing?
