It seems this issue, posted last year was fixed only for the android SDK but unfortunately the problem still exists on the Web SDK.
The player has no issues picking up the correct audio labels in HLS streams but is unable to pick up the AdaptationSet label present in the manifest of DASH streams.
Example Manifest >> https://fliikamediaservice-usea.streaming.media.azure.net/2a3929ec-8b6b-43b6-a542-81051451c942/Black-Widow.ism/manifest(format=mpd-time-cmaf)
This is what I’m console logging when I run player.getAvailableAudio();
Thanks for reaching out on this. I’ve passed on your request to support the Label element for Dash to our Product team. I can’t give you any ETA on when this feature will be implemented so please keep an eye on the Release Notes page for Player Web. https://developer.bitmovin.com/playback/docs/release-notes-web
In the meantime, we have the SourceLabelingConfig API available to assign more user-friendly descriptions to audio and subtitle tracks. Please see the documentation here - SourceLabelingConfig | Bitmovin Player API 8.150.0
