流内：兼容的 VAST 封装播放器

流内广告区可提供两种类型的 VAST 元素： Inline 和 Wrapper。Inline 元素是为标准视频文件提供服务的常规视频广告，而 Wrapper 元素则包含一个指向外部 VAST 标签的重定向，反过来也可以为其他 Inline 或 Wrapper 元素提供服务。

最独特的组件是 "VASTAdTagURI"，它指定了该广告重定向到的外部 VAST：

<VAST version="3.0">

        <Wrapper>

要想通过这些营销活动实现流量盈利，您必须确保用于显示广告的播放器与包装器兼容，这意味着它可以获取并读取包装器标签中的内容。

The players listed in In-Stream: How to implement In-Stream Part 2 - Implementation examples are 100% VAST compatible with our ads, meaning they will also work for Wrapper VAST tags:

• FluidPlayer
• JwPlayer
• VideoJs
• FlowPlayer
• Kernel Video Sharing

如果您没有使用上述任何播放器，请在您的播放器中添加以下 测试 VAST 标签，以测试播放器的 Wrapper 兼容性：

该 VAST 标签旨在始终为封装元素提供服务。如果您的播放器无法显示此元素，请考虑更新或更换播放器。如果您无法更改播放器，请确保禁用所有内流广告区的 VAST Wrapper 支持。

这样，您的内流广告区就不会显示任何 Wrapper 元素，从而避免内流广告服务出现任何问题，并确保您的流量可以盈利。
