Detailed Description

The OMX_VERSIONTYPE union is used to specify the version for a structure or component. For a component, the version is entirely specified by the component vendor. Components doing the same function from different vendors may or may not have the same version. For structures, the version shall be set by the entity that allocates the structure. For structures specified in the OMX 1.1 specification, the value of the version shall be set to 1.1.0.0 in all cases. Access to the OMX_VERSIONTYPE can be by a single 32 bit access (e.g. by nVersion) or by accessing one of the structure elements to, for example, check only the Major revision.
