How to set up I-slice keyframe interpretation

By default, I-slices are treated as keyframes. You can add the isISliceKey property to your Wowza™ media server live application configuration if you don't want I-slices to be treated as keyframes.

You can configure application properties in Wowza Streaming Engine™ Manager or by editing [install-dir]/conf/[application]/Application.xml. If you make changes to Application.xml and you're using Wowza Streaming Engine media server software, any supported settings are displayed in the manager the next time it's started. Wowza Media Server™ software doesn't support Wowza Streaming Engine Manager, so you must edit Application.xml in a text editor if you're running Media Server software.

Wowza Streaming Engine Manager configuration

  1. In the manager Welcome page, click the Applications tab at the top of the page.
  2. In the Applications contents panel, click the name of your live application (such as live).
  3. On the live application page Properties tab, click Custom in the Quick Links bar.
    Note: Access to the Properties tab is limited to administrators with advanced permissions. For more information, see Manage credentials.
  4. In the Custom area, click Edit.
  5. Click Add Custom Property, specify the following settings in the Add Custom Property dialog box, and then click Add:
    • Path - Select /Root/Application/Streams.
    • Name - Enter isISliceKey.
    • Type - Select Boolean.
    • Value - Enter false.
  6. Click Save, and then restart the application when prompted to apply the changes.

XML configuration

  1. Use a text editor to open the [install-dir]/conf/[application]/Application.xml file for your live application and add the following property to the Streams/Properties container. Be sure to add the properties to the correct <Properties> container in Application.xml as there are several such containers in the file.
  2. Restart the Wowza media server software to apply the changes.
