Subtitles not displayed in CastPlayer

[anup1245]

Hi I was trying use cast player to cast video, but subtitles are not shown. I saw the code, and could not find a way to populate subtitles.
I tried to use Custom MediaItemConverter but it did not help

  override fun toMediaQueueItem(mediaItem: MediaItem): MediaQueueItem {
    val metadata = com.google.android.gms.cast.MediaMetadata(
      com.google.android.gms.cast.MediaMetadata.MEDIA_TYPE_MOVIE
    )
   
    val mediaInfo = MediaInfo.Builder(mediaItem.playbackProperties!!.uri.toString())
      .setStreamType(MediaInfo.STREAM_TYPE_BUFFERED)
      .setContentType(mediaItem.playbackProperties!!.mimeType!!)
      .setMetadata(metadata)
      .setMediaTracks(createSubtitleMediaTracks(mediaItem.playbackProperties?.subtitles))
      .setCustomData(getCustomData(mediaItem))
      .build()
    return MediaQueueItem.Builder(mediaInfo).build()
  }

I see in the CastPlayer, the video is loaded using

remoteMediaClient.queueLoad(
        mediaQueueItems,
        min(startIndex, mediaQueueItems.length - 1),
        getCastRepeatMode(repeatMode),
        startPositionMs,
        /* customData= */ null);

That does not set any active track ids for subtitles. If we use

remoteMediaClient.load(mediaInfo, mediaLoadOptions)

that sets setActiveTrackIds

Also using StyledPlayerView for normal play on device, but when casting, the captions button is disabled.

Is there a way to cast subtitles using Cast Player?

using exoplayer 2.15.1

This is currently not supported with CastPlayer. Accordingly CastPayer does not advertise this feature and the StyledPlayerView correctly does not offer setting text tracks.

Thanks for reporting. I'm closing as a duplicate of #8669.
