Below is my finding:
1. When play an HLS stream and have a less than 8 kb timed metadata raw size then we are getting raw data and able to display it during the playback
2. When playing an HLS stream and having a more than 8 kb timed metadata raw size then we are not getting raw data and are not able to display it during the playback. When Play the same HLS Stream on other platforms(Website, iOS, Android) then able to read this time metadata
