| | | * 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. |
