live streaming HLS with alternate audio tracks

Hi, is there any way using wowza to do a live streaming (HLS output) with alternate audio tracks from a RTMP input with multiple audio tracks?

Thanks!

Hi,

Have you looked at the ModuleMultiTrackVod article? This allows you to select specific audio tracks using query parameters, e.g. for an HLS stream

Thanks Paul, but looks like this “tool” only works for VOD. Does it work for live streams too?

Hi,

Yes, my apologies, looks like I left out the live audio selection example. You can configure Wowza to choose an audio track from an HLS stream by creating a smil file using separate stream files to extract each audio input Please see this article for some examples of how this can work.
