  *
  * Useful to check and match library version in order to maintain
  * backward compatibility.
  *

  * The FFmpeg libraries follow a versioning sheme very similar to
  * Semantic Versioning (http://semver.org/)
  * The difference is that the component called PATCH is called MICRO in FFmpeg
  * and its value is reset to 100 instead of 0 to keep it above or equal to 100.
  * Also we do not increase MICRO for every bugfix or change in git master.
  *

  * Prior to FFmpeg 3.2 point releases did not change any lib version number to
  * avoid aliassing different git master checkouts.
  * Starting with FFmpeg 3.2, the released library versions will occupy
  * a separate MAJOR.MINOR that is not used on the master development branch.
  * That is if we branch a release of master 55.10.123 we will bump to 55.11.100
  * for the release and master will continue at 55.12.100 after it. Each new
  * point release will then bump the MICRO improving the usefulness of the lib
  * versions.
