What happened?

A bug happened!

I am experiencing an issue with the onTextTracks callback where the callback does not log subtitle track information as expected. Despite the subtitles being visibly selected and VTT files being fetched (as observed in the network tab), the callback output does not reflect the subtitle tracks.

Implemented onTextTracks and they should work according to this PR

Reproduction

Step to reproduce this bug are:

I tried to make a snack; however, it seems react-native-video is unsupported. Please view this snippet as the minimal reproduction code:

import Video, {
  VideoRef,
  SelectedTrackType,
  OnTextTracksData,
} from 'react-native-video';

function App(): React.JSX.Element {
  const videoRef = useRef<VideoRef>(null);

  const handleTextTracks = (e: OnTextTracksData) => {
    console.log(`TEXT TRACKS: ${JSON.stringify(e, null, 2)}`);
  };

  return (
    <SafeAreaView>
      <Video
        ref={videoRef}
        style={styles.videoContainer}
        selectedTextTrack={{
          type: SelectedTrackType.INDEX,
          value: 1,
        }}
        controls
        source={{
          uri: 'https://bitmovin-a.akamaihd.net/content/sintel/hls/playlist.m3u8',
        }}
        muted={true}
        onTextTracks={handleTextTracks}
      />
    </SafeAreaView>
  );
}

Logs

TEXT TRACKS: {
  "textTracks": [
    null,
    null,
    null,
    null
  ],
  "target": 3
}

• Using react-native-video version ^6.0.0-beta.5.

I tried running my test uri in the example app and got the same thing when trying to log the data from onTextTracks

@freeboub Do you think you could give this a look 🙏🏽.

Or could you tell me what uri you used when testing?
