You can specify the number of threads for each stream at every step individually:

 > ffmpeg -threads:v:0 1 -i in.avi -threads:a:0 1 -c:a mp3 -threads:v:0 8 -c:v 
libx264 -y out.mp4

Here it uses 1 thread for the decoder, 1 for the audio and 8 threads for the 
video encoder. Not sure if this is what you are looking for. Know you can use 
multiple ffmpeg processes with pipes when you don't like using threads.
