/**

*
* 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.
