Import AC-3 elementary streams for Dolby Digital audio

Wowza Streaming Engine can import AC-3 elementary streams to allow Dolby Digital (AC-3) and Dolby Digital Plus (Enhanced AC-3) audio from MPEG-TS encoders to pass through unaltered for delivery using HLS and MPEG-DASH streaming. 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.
