I am quite new to ffmpeg, I've been searching the ffmpeg documentation and
web pages, but have not find a solution to my problem 

I want to use ffmpeg to do some filters on a video files 
instead of using multithread  option, I want to split my video into some
parts and then do changes with ffmpeg (for example make it black and
white),then merge them 

do you think this is a correct way to doing change on divided video parts
and  merge them instead of using multithread option in ffmpeg 

the goal of my research is to improve performance of subsystem (for example
a server with 5 CPU and each CPU has 4 cores) with splitting and merging a
big videos and execute each parts to do same jobs with ffmpeg on different
cores (not using multithreading strategy)
