I'm trying to test mp4 videos with multiple audio tracks on the Chromecast but audioTracks appears to be missing from the video element. Is there some way for me to switch audio tracks on mp4 videos?
If you look on the Release Notes of Google Cast, it seems that audioTracks is not yet supported on the Cast API. This related SO question also ask about audioTrack on chromecast, but the owner of the question found out that it is not yet supported. For more information, you can check this Media Player Library and Audio Device that is currently or only available for the Cast API.
