ffmpeg -f lavfi -i nullsrc -c:v libx264 -preset help -f mp4 -

Among other things it will display:
x264 [error]: invalid preset 'help'
[libx264 @ 0x8c3240] Error setting preset/tune help/(null).
[libx264 @ 0x8c3240] Possible presets: ultrafast superfast veryfast
faster fast medium slow slower veryslow placebo
[libx264 @ 0x8c3240] Possible tunes: film animation grain stillimage
psnr ssim fastdecode zerolatency

I'll try to clarify the wiki article.
