Is there anyway i could change audio language in casting in android ?
Since exoplayer doesn`t allow changing tracks while casting video, So changing tracks doesnt allowed. and after raising a issue in exoplayer https://github.com/google/ExoPlayer/issues/9687
and recieved CastPlayer currently does not support changing tracks I'm afraid. We have the issue marked as an enhancement
and https://github.com/google/ExoPlayer#deprecation` its deprecated will no longer have update on it.
