===== libaom Options =====

libaom offers the following rate-control modes which determine the quality and file size obtained:

  * Constant quality.
  * Constrained quality.
  * 2-pass average bitrate.
  * 1-pass average bitrate.

<WRAP info>
**NOTE:**  For a list of libaom options, run <code bash>ffmpeg -h encoder=libaom-av1</code>
