HLS VOD stream of MP4 with multiple embedded audio tracks

Wowza Streaming Engine

Hi Support Team,

I have been trying to stream a MP4 having 8 embedded audio tracks. I got the link where on using ModuleMultiTrackVOD module I can select different audio tracks to be played using query string but the problem now is that my player is unable to detect the different streams, until and unless player detects and list the different tracks how I can be able to select one out of them. Can you tell me which config I need to enable in order to make the stream details available to the player in order to list them. TIA

Hello,

This question was handled in the created ticket (#183227)

I am posting the outcome of that ticket here.

At this time it is not possible to have Wowza Streaming Engine deliver TS chunks containing multiple audio tracks.

The recommended option is to use the SMIL descriptor files where each audio track is defined using the

audioindexquery parameter. Mutiple video tracks can be defined by using the videoindex query parameter.

Here is a sample of such a SMIL file:

I hope it helps.

Hello,

reviving a bit this topic,

I actually tried to do the same with the current WSE graphical interface, but it does not accept special character in the source. Is this just a limitation of the interface but that I can create such smil file manually and use, or is this not possible ?

Thx
