Question

我使用适用于iOS的Google互动式媒体广告：Vast（V3）。我确实下载了iOS（Beta）样本。并尝试将内容URL（kTestAppAdTagUrl_Instream1）更改为我的一个。我收到了一条错误消息

2014-03-31 14:34:30.531 SampleApp[1450:60b] Relayout
2014-03-31 14:34:30.565 SampleApp[1450:60b] AdsManager event (Loaded).
2014-03-31 14:34:31.364 SampleApp[1450:60b] AdsManager error with type: 2
code: 403
message: Linear assets were found in the VAST ad response, but none of them matched the video player's capabilities.

这是我的MediaFile标签：

<MediaFiles>
<MediaFile delivery="progressive" bitrate="400" width="640" height="480" type="video/x-mp4">
<![CDATA[
http://www.xxxx.mp4
]]>
</MediaFile>
<MediaFile delivery="progressive" bitrate="400" width="640" height="480" type="video/x-flv">
<![CDATA[

</MediaFile>
<MediaFile delivery="progressive" bitrate="400" width="640" height="480" type="video/webm">
<![CDATA[
http://www.xxxx.webm
]]>
</MediaFile>
</MediaFiles>

这是原始媒体文件标签：

<MediaFiles>
<MediaFile id="GDFP" delivery="progressive" width="320" height="240" type="video/3gpp" bitrate="232">

我不知道如何解决这个问题

谢谢

Answer 1

您的MP4资产类型不正确，视频/ x-mp4无效。

将其更改为：

<MediaFile ... type="video/mp4"><![CDATA[http://www.xxxx.mp4]]></MediaFile>

<强>有效：
视频/ X-FLV
视频/ MP4
视频/ WEBM
视频/ 3GPP

Answer 2

可能是您传递的无效视频文件网址吗？ http://www.xxxx.mp4？

VAST线性资产不匹配
