使用客户端元数据跟踪叠加广告

MediaTailor 将叠加广告置于可nonLinearAdsList用的范围内。 MediaTailor 客户端跟踪API有两个根对象，名为avails和。nonLinearAvails如果VAST响应是 wit WMAP h o breakType nonlinear f，则可用元数据位于nonLinearAvails根对象内。如果VAST响应是VMAP带有 of breakType 的响应linear，或者是没有的普通VAST响应VMAP，则可用元数据位于avails根对象内。

有关客户端跟踪的更多信息，请参阅客户端广告跟踪。

以下示例显示了breakType值为的普通VASTVMAP响应或响应linear。
