/**
 * OMX_CONFIG_ANDROID_VENDOR_EXTENSIONTYPE is the structure for an Android vendor extension
 * supported by the component. This structure enumerates the various extension parameters and their
 * values.
 *
 * Android vendor extensions have a name and one or more parameter values - each with a string key -
 * that are set together. The values are exposed to Android applications via a string key that is
 * the concatenation of 'vendor', the extension name and the parameter key, each separated by dot
 * (.), with any trailing '.value' suffix(es) removed (though optionally allowed).
 *
 * Extension names and parameter keys are subject to the following rules:
 *   - Each SHALL contain a set of lowercase alphanumeric (underscore allowed) tags separated by
 *     dot (.) or dash (-).
 *   - The first character of the first tag, and any tag following a dot SHALL not start with a
 *     digit.
 *   - Tags 'value', 'vendor', 'omx' and 'android' (even if trailed and/or followed by any number
 *     of underscores) are prohibited in the extension name.
 *   - Tags 'vendor', 'omx' and 'android' (even if trailed and/or followed by any number
 *     of underscores) are prohibited in parameter keys.
 *   - The tag 'value' (even if trailed and/or followed by any number
 *     of underscores) is prohibited in parameter keys with the following exception:
 *     the parameter key may be exactly 'value'
 *   - The parameter key for extensions with a single parameter value SHALL be 'value'
 *   - No two extensions SHALL have the same name
 *   - No extension's name SHALL start with another extension's NAME followed by a dot (.)
 *   - No two parameters of an extension SHALL have the same key
 *
 * This config can be used with both OMX_GetConfig and OMX_SetConfig. In the OMX_GetConfig
 * case, the caller specifies nIndex and nParamSizeUsed. The component fills in cName,
 * eDir and nParamCount. Additionally, if nParamSizeUsed is not less than nParamCount, the
 * component fills out the parameter values (nParam) with the current values for each parameter
 * of the vendor extension.
 *
 * The value of nIndex goes from 0 to N-1, where N is the number of Android vendor extensions
 * supported by the component. The component does not need to report N as the caller can determine
 * N by enumerating all extensions supported by the component. The component may not support any
 * extensions. If there are no more extensions, OMX_GetParameter returns OMX_ErrorNoMore. The
 * component supplies extensions in the order it wants clients to set them.
 *
 * The component SHALL return OMX_ErrorNone for all cases where nIndex is less than N (specifically
 * even in the case of where nParamCount is greater than nParamSizeUsed).
 *
 * In the OMX_SetConfig case the field nIndex is ignored. If the component supports an Android
 * vendor extension with the name in cName, it SHALL configure the parameter values for that
 * extension according to the parameters in nParam. nParamCount is the number of valid parameters
 * in the nParam array, and nParamSizeUsed is the size of the nParam array. (nParamSizeUsed
 * SHALL be at least nParamCount) Parameters that are part of a vendor extension but are not
 * in the nParam array are assumed to be unset (this is different from not changed).
 * All parameter values SHALL have distinct keys in nParam (the component can assume that this
 * is the case. Otherwise, the actual value for the parameters that are multiply defined can
 * be any of the set values.)
 *
 * Return values in case of OMX_SetConfig:
 *   OMX_ErrorUnsupportedIndex: the component does not support the extension specified by cName
 *   OMX_ErrorUnsupportedSetting: the component does not support some or any of the parameters
 *       (names) specified in nParam
 *   OMX_ErrorBadParameter: the parameter is invalid (e.g. nParamCount is greater than
 *       nParamSizeUsed, or some parameter value has invalid type)
 *
 * STRUCTURE MEMBERS:
 *  nSize       : size of the structure in bytes
 *  nVersion    : OMX specification version information
 *  cName       : name of vendor extension
 *  nParamCount : the number of parameter values that are part of this vendor extension
 *  nParamSizeUsed : the size of nParam
 *                (must be at least 1 and at most OMX_MAX_ANDROID_VENDOR_PARAMCOUNT)
 *  param       : the parameter values
