many source mages have tried and many failed to create a parallel computation.
as a last resort you can still hook up parallel to single threaded processes.
this works best with # of files greater than number of your CPUs and there is no advantage when you run this just on one file.

Code:

#convert all wavs to mp3 in folder with parallel
find . -name '*.wav' | parallel lame -V2 {} -o {}.mp3

Code:

#convert all mkv in current folder to videocodec:xvid/audiocodec:mp3 avi. xvid bitrate 1MB/s. mp3 quality -V2
parallel -j4 ffmpeg -i {} -b:v 1M -vcodec libxvid -acodec libmp3lame -q:a 2 {.}.avi ::: ./*.mkv
