[FFmpeg-user] How do I get the presets I can use

[Cecil Westerhof]

I want to play a bit with -preset, but how do I get the correct list
with parameters? At one place I found:
  - veryslow
  - slow
  - normal
  - fast
  - faster
  - veryfast
  - ultrafast

But at another I also found:
 - superfast
 - medium
 - slower
 - placebo

but was missing normal.

I tried ffmpeg -h, but this only gives:
    -pre preset         preset name

I tried:
    ffmpeg -h -pre
and:
    ffmpeg -h pre
but that just gives the same as:
    ffmpeg -h
