But wouldn't it be useful to simply mention it's existence, syntax and
general meaning? Additionally in the paragraphs of each codec the values
and meanings could be documented or at least link to an external source.
How it's determined, if the option is meant for the video or the audio
codec and how to do, if a different level is wanted for each codec?
