/** |

|

|
* 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. |
