'Video frame freeze on android tv using media player?
I am trying to play mp4 URL on android TV with use of media player
if (mMediaPlayer == null) {
mMediaPlayer = MediaPlayer()
mMediaPlayer.setOnPreparedListener(mPreparedListener)
try {
executors = Executors.newFixedThreadPool(1)
val runnable = Runnable {
mMediaPlayer?.setDataSource(mContext, mUri)
mMediaPlayer?.prepareAsync()
}
executors!!.submit(runnable)
} catch (e: Exception) {
}
}
Playing the file
private var mPreparedListener: MediaPlayer.OnPreparedListener? =
MediaPlayer.OnPreparedListener { mp ->
mp.start()
}
Simple code but on one of the TV's the stream freezes for 1 or 2 seconds.
Testing Device is
Device Name : Sony Android TV
Device Size : 43”
Version : 8.0.0
Model : BRAVIA 2K GB ATV3

Can't seem to figure out what could be causing the issue of frame freeze.
