HowTo CREATE MULTITRACK CHANNEL IN WOWZA STREAMING ENGINE
Offline
We’re familiar with ABR stream playback, where we pick between multiple video bitrates. But what about streams with different audio tracks and different video pictures? Sometimes channel can be switched to different languages or different comments.
Wowza Streaming Engine allows to configure this kind of streams. The main gear is SMIL file where few sources can be aggregated and player settings can be set. This post describes how to set up audio multitracking step by step.
Set up channels-sources
The first step – ensure your parts of multitrack stream play back fine. Add to your Wowza origin server new channels: one per each audio track. You can start receiving streams permanently. Usually I configure it on configuration, you can do it with stream files.
If all audio tracks locate at the same stream source – then you need to find PID of each and point them on your stream configuration. Usually it comes from JSON configuration. Here is my example to split one source into multiple audio channels of channel 12.
