I am just getting started with the Bitmovin player, and have a source MP4 with four audio streams. The Player doesn’t offer the audio streams as a selectable list.
I am assuming this is because the streams don not have the required metadata to be offered by the player, but what is the required metadata?
Should every stream have a title or a language attibute? Or both?
All the best, Stephen

Thanks for your question @stephen.mcconnachie .
Browsers don’t really surface the secondary tracks from MP4 files, nor allow to select these. There is therefore not really a way to achieve this for Video Players either. This is rather a platform (browser) limitation than a player limitation.
The correct way to deliver multi-audio streams is to encode each audio tracks in separated segments, which allows the player to download segments only from the audio track which has been selected.
You can take a look into our player demo and sample DASH and HLS multi audio streams.

Please let me know in case you have any additional question.

Thanks! I’ll use that method instead.
