Configure alternate audio

Adobe Media Server has support for including multiple language tracks for HTTP video streams, without requiring duplication and repackaging of the video for each audio track. This feature, called as “late” binding of audio tracks allow content providers to easily provide multiple language tracks for a given video asset, at any time before or after the asset’s initial packaging. The initial packaging of the video asset can include an audio track, and the publisher can still choose to provide one or more additional audio tracks for the video. Video players can provide support for allowing the viewers to switch between audio tracks either before or during playback.

Clients can pick the appropriate audio

The primary use case of this feature is that content providers can publish video content in multiple languages. Viewers can subscribe to such videos using the OSMF player, which allows audio track switching before or during playback.
