Fix missing or garbage video (MPEG-TS) in Wowza Streaming Engine

Configure Wowza Streaming Engine™ media server software to manage unaligned video packets that may be sent by some MPEG-TS-based encoders. These unaligned packets appear as garbage or missing video when they're played.

You can specify application properties in Wowza Streaming Engine Manager or by editing [install-dir]/conf/[application]/Application.xml. If you make changes to Application.xml, any supported settings are displayed in Wowza Streaming Engine 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.

Manage unaligned video packets in Wowza Streaming Engine Manager


  1. 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 RTP Jitter Buffer 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. Click Edit in the RTP Jitter Buffer properties area, select the Enabled check box next to mpegtsVideoIsAligned and ensure the property is set to False.
     
  5. Click Save, and then restart the application when prompted to apply the changes.

Manage unaligned video packets in Application.XML


  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 RTP/Properties container. Be sure to add the properties to the correct <Properties> container in Application.xml as there are several in the file.
