PWI Multilingual streaming Addon for Wowza Streaming Engine

The Addon helps to create live broadcasts with multiply language tracks leveraging HLS streaming protocol features. It supports different methods to publish streams to Wowza Streaming Engine and could be used for VOD streaming as well. The methods to publish video and multilingual audio are:

  • SRT protocol with multiply language PIDs in SPTS/MPTS MPEGTS
  • MPEGTS multicast or unicast with multiply language PIDs in SPTS/MPTS
  • RTMP streams with video/audio or audio only
  • RTMP streams with translated language audio track in one of left/right mono channels

Ingested stream is transmuxed to HLS m3u8 playlist with multiply audio streams and could be played in any HLS player capable to switch audio tracks.

The module is also capable to record live stream to MP4 video files with a single language audio track and stream them as HLS VOD with multiply languages switching in the player similar to live broadcast mode.
