Import AC-3 elementary streams

Wowza Streaming Engine (and Wowza Media Server 3.5.1 or later) can import AC-3 elementary streams using Apple HLS (Cupertino) and MPEG-DASH streaming to allow Dolby Digital (AC-3) and Dolby Digital Plus (Enhanced AC-3) audio from MPEG-TS encoders to pass through unaltered for delivery. This lets your customers experience immersive surround-sound audio when streaming on media devices such as Apple TV, Sony PlayStation 3 (PS3), hybrid set-top boxes, and smart TVs.

Note: The mpegtsImportAC3 property will apply to all streams delivered by the application. For more information on only changing the property for a single stream, see Specify per-stream settings in Wowza Streaming Engine .stream files.

Be sure to add the property to the correct <Properties> container in Application.xml as there are several such containers in the file.
     
    <Property>
        <Name>mpegtsImportAC3</Name>
