     35 * Useful to check and match library version in order to maintain
     36 * backward compatibility.
     37 *
     38 * The FFmpeg libraries follow a versioning sheme very similar to
     39 * Semantic Versioning (http://semver.org/)
     40 * The difference is that the component called PATCH is called MICRO in FFmpeg
     41 * and its value is reset to 100 instead of 0 to keep it above or equal to 100.
     42 * Also we do not increase MICRO for every bugfix or change in git master.
     43 *
     44 * Prior to FFmpeg 3.2 point releases did not change any lib version number to
     45 * avoid aliassing different git master checkouts.
     46 * Starting with FFmpeg 3.2, the released library versions will occupy
     47 * a separate MAJOR.MINOR that is not used on the master development branch.
     48 * That is if we branch a release of master 55.10.123 we will bump to 55.11.100
     49 * for the release and master will continue at 55.12.100 after it. Each new
     50 * point release will then bump the MICRO improving the usefulness of the lib
     51 * versions.
