On the page:
https://trac.ffmpeg.org/wiki/Encode/H.264
It states:
You can see a list of current presets with -preset help, and what settings they
apply with x264 --fullhelp.
I get "trailing options were found on the commandline", with 2.2 compiled today,
if I use "ffmpeg -preset help".
I have tried in several ways, the most recent being:
ffmpeg -i testvid.mov -c:v libx264 -preset help -crf 22 -c:a copy testvid.mkv

Error while opening encoder for output stream #0:0 - maybe incorrect parameters
such as bit_rate, rate, width or height
I try changing it to -vpre help, and get:
File for preset 'help' not found
I was trying to figure out why I don't have certain presets, and while I can
just go look at the files, the wiki says this should work.
