Wowza Transcoder has a default sort buffer of 750 milliseconds. A buffer is needed in order to have a complete frame for transcoding or transrating a stream.
This is the only way to configure the sort buffer for Wowza Streaming Engine media server software version 4.5.0.01 and earlier. For Wowza Streaming Engine 4.5.0.02 and later, you can also configure the sort buffer in the Transcoder templates. See Template details - SortBuffer
This sort buffer can be controlled by adding the following properties to the <Transcoder>
container in [install-dir]/conf/[application]/Application.xml
(be sure to get the correct <Properties>
container - there are several in the Application.xml
