Hi! I've (semi) successfully moved the media library to Azure Blob Storage and also configured the Azure CDN. It works as expected for my images. But my mp4-files which are rendered in html video-tags doesn't get picked up by the CDN.

Can anyone explain why and if there's something I can do about it?

<FileSystemProviders>
  <!-- Media -->
  <Provider alias="media" type="Our.Umbraco.FileSystemProviders.Azure.AzureBlobFileSystem, Our.Umbraco.FileSystemProviders.Azure">
    <Parameters>
      <add key="containerName" value="media-local"/>
      <add key="rootUrl" value="https://xxx.blob.core.windows.net/"/>
      <add key="connectionString" value="***"/>
      <!--
    Optional configuration value determining the maximum number of days to cache items in the browser.
    Defaults to 365 days.
  -->
      <add key="maxDays" value="365"/>
      <!--
    When true this allows the VirtualPathProvider to use the deafult "media" route prefix regardless 
    of the container name.
  -->
      <add key="useDefaultRoute" value="true"/>
      <!--
    When true blob containers will be private instead of public what means that you can't access the original blob file directly from its blob url.
  -->
      <add key="usePrivateContainer" value="false"/>
    </Parameters>
  </Provider>

</FileSystemProviders>
