wowza 的 mediaReaderRandomAccessReaderClass 问题 restful api

Question

我在 Ubuntu 14.04 使用 WowzaStreamingEngine 4.4.1。我使用 restful api 并创建了 vod 应用程序 (restful_vod) 作为示例，它没有工作，没有流式传输 vod 文件。这就是为什么，我比较默认 vod 应用程序和 restful_vod 应用程序的 application.xml 个文件。 MediaReader 属性之间存在差异。默认 vod 应用程序在那里没有属性但 restful_vod 有以下内容：

<MediaReader>
  <!-- Properties defined here will override any properties defined in conf/MediaReaders.xml for any MediaReaders loaded by this applications -->
  <Properties>
    <Property>
      <Name>randomAccessReaderClass</Name>
      <Value></Value>
      <Type>String</Type>
    </Property>
  </Properties>
</MediaReader>

当我删除名为属性的 randomAccessReaderClass 时，它开始工作了。我意识到 mediaReaderRandomAccessReaderClass 参数在 restful api 端管理它的值。但是我找不到在使用 restful api 时阻止添加它的方法。我尝试不设置 mediaReaderRandomAccessReaderClass 值并将 mediaReaderRandomAccessReaderClass 设置为 false、null 和空字符串。

有什么方法可以防止添加它或为此设置默认工作值吗？

谢谢。

您可以通过如下设置来设置默认的 mediaReaderRandomAccessReaderClass： "mediaReaderRandomAccessReaderClass": ""

在生成的 Application.xml 文件中，MediaReader 容器将为空白，这表明它将使用默认值：

<MediaReader>
    <!-- Properties defined here will override any properties defined in conf/MediaReaders.xml for any MediaReaders loaded by this applications -->
    <Properties>
    </Properties>
</MediaReader>

例如，用于创建 VOD 文件的有效 REST API 命令如下所示。

curl -X POST --header 'Accept:application/json; charset=utf-8' --header 'Content-type:application/json; charset=utf-8' http://localhost:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/testvod -d'
