version takes the form "$major.$minor.$patch" |

| 39 |
$patch is incremented when there is no api change |
#define XVID_API_UNSTABLE |
|
$minor is incremented when the api is changed, but remains backwards compatible |
|
|
$major is incremented when the api is changed significantly |

when initialising an xvid structure, you must always zero it, and set the version field. |
