27 #ifndef AVUTIL_VERSION_H
28 #define AVUTIL_VERSION_H
33 * @addtogroup version_utils
35 * Useful to check and match library version in order to maintain
36 * backward compatibility.
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.
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

98 * FF_API_* defines may be placed below to indicate public API that will be
99 * dropped at a future version bump. The defines themselves are not part of
100 * the public API and may change, break or disappear at any time.
102 * @note, when bumping the major version it is recommended to manually
103 * disable each FF_API_* in its own commit instead of disabling them all
104 * at once through the bump. This improves the git bisect-ability of the change.
