Fix TS packet alignment in UDP packets

Some MPEG-TS encoders don't align TS packets correctly in UDP packets. When this happens, you'll get the following warning messages in the logs:

RTPDePacketizerMPEGTS.handleRTPPacket: Out of sync: 0x[nn]  

See the following steps to fix TS packet alignment in UDP packets for MPEG-TS encoders.

Note: Wowza Streaming Engine only allows a single rtpDePacketizerWrapper value. If you configured a jitter buffer or packet recorder that uses the same rtpDePacketizerWrapper, remove it before performing the steps below.

Fix TS packet alignment in UDP packets in Wowza Streaming Engine Manager

  1. Click the Applications tab and then click the name of your live application in the contents panel.
  2. On the 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.
  3. Click Edit in the RTP Jitter Buffer properties area, select the Enabled check box next to rtpDePacketizerWrapper, and then enter the value com.wowza.wms.rtp.depacketizer.RTPDePacketizerWrapperReChunkMPEGTS.  
  4. Click Save, and then restart the application to apply the changes. 

Fix TS packet alignment in UDP packets in 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 property to the correct <Properties> container in Application.xml as there are several such containers in the file.
  2. Restart Wowza Streaming Engine to apply the changes.
