Bug

I want to set a subtitle and audio in the CastPlayer, but I Can't.

for subtitle, I Set :

 val mediaItem = MediaItem.Builder()
            .setUri(Uri.parse(videoUrl))
            .setMimeType(mediaType)
            .setMediaMetadata(movieMetadata)
            .setTag(videoUrl)
            .setSubtitleConfigurations(
                listOf(MediaItem.SubtitleConfiguration.Builder(Uri.parse(subtitleUrl)).build())
            ).build()

for the subtitle, it didn't work.
After that I used this: #8669 (comment)
First I converted from MediaItem to MediaQueueItem, and when I was making MediaQueueItem I Set Subtitle MediaTracks, After making the MediaQueueItem, I Converted the MediaQueueItem to MediaItem, and then I set the MediaItem to CastPlayer. but after preparing CastPlayer, I can't find Subtitle Tracks.
