What's New in AMS 5.0.3

  • Protected RTMP onDemand Enhancements

    • Logging improvement for billing: The Adobe Media Server access log supports an additional column "x-sprotection-ver." This is logged with the application and stream events with value "1" if the stream is protected (PRTMP enabled).

    • Integration of common key and white-list access with file-plugin interface: The common key and white-list access in the Protected RTMP on-demand workflow is routed through file adaptor if configured for handling "PRTMP" requests. Following configuration is added to server.xml:

      Root/Server/Plugins/FilePlugin: <!-- This section configures PRTMP common key and file --> <!-- whitelist file operations in present plugin. By --> <!-- default such operations won't be managed by this --> <!-- plugin. --> <Content type="PRTMP">false</Content>
    • DRM refresh: The DRM refresh is needed if there is a change in swf whitelist on runtime or update of common-key. New DRM will be in effect as soon as new clients subscribe in the following scenarios:

      • new whitelist hashes are provided through the auth adaptor or

      • whitelist folder modification time is changed

       

      This is independent of whether the update interval is configured or not. If only the exiting whitelist file is modified and the swf folder modified time is not updated, the new DRM is in effect from the next update interval onwards.

      The existing streams will play with the old DRM.

      You can update F_APP_PRTMP_SWF_WHITELIST or F_APP_PRTMP_AIR_WHITELIST at the time of connect. This updates the swf whitelist for whole application.

     

  • Common-key update: Common key can be updated in the same location. The Origin Server flushes the cache and reloads the data.

  • Key rotation: You can rotate the key for protected RTMP live playback. You can periodically change the encryption key by specifying the frequency of content encryption key change. Rotated keys are generated dynamically using the common key and content id.

    Added configuration:

    <EnableKeyRotation>true</EnableKeyRotation> <KeyRotationInterval>500</KeyRotationInterval> // in seconds

    Added configuration in Application.xml.

    <Application> <ProtectedRTMP enabled="true"></ProtectedRTMP> <EnableKeyRotation>true</EnableKeyRotation> <KeyRotationInterval>500</KeyRotationInterval> ... </Application>

What's New in AMS 5.0.1

Support for closed captions

Closed captioning allows the content provider to display text overlayed on the video content thus providing additional information about the video content to the consumers. Closed captioning is primarily used as an accessibilty tool to show a transcription of the audio portion of the video content as it occurs. The term “closed” in closed captioning indicates that the captions are not made part of the video by default. Hence, the captions have to be decoded/extracted by an external tool. For more information on configuring the server to support closed captions, see Configure closed captioning.

Support for alternate audio

Adobe Media Server 5.0.1 has support for including multiple language tracks for HTTP video streams, without requiring duplication and repackaging of the video for each audio track. This feature, called as “late” binding of audio tracks allow content providers to easily provide multiple language tracks for a given video asset, at any time before or after the asset’s initial packaging. The initial packaging of the video asset can include an audio track, and the publisher can still choose to provide one or more additional audio tracks for the video. Video players can provide support for allowing the viewers to switch between audio tracks either before or during playback. For more information on configuring the server to support alternate audio, see Configure alternate audio.
