Audio keeps playing when exoplayer releases

I am using Exoplayer in my dialog. I want the video to play automatically when dialog opens. When
simpleExoPlayer.prepare() snippet is active I am able to do autoplay but when I close the dialog audio keeps playing. Before activating simpleExoPlayer.prepare() audio stops when I dismiss dialog. Is there another method to autoplay exoplayer or stop the audio when dialog dismiss?
class VideoViewDialog (context: Context) : BaseDialog<LayoutDialogVideoViewBinding>(context) {
private var videoUrl : String = ""
private lateinit var simpleExoPlayer: ExoPlayer
override fun populateUi() {
setCanceledOnTouchOutside(true)
mBinding?.apply {
initializePlayer()
}
}
private fun initializePlayer() {
val mediaDataSourceFactory: DataSource.Factory = DefaultDataSource.Factory(context)
val mediaSource = ProgressiveMediaSource.Factory(mediaDataSourceFactory).createMediaSource(
MediaItem.fromUri(videoUrl))
val mediaSourceFactory: MediaSource.Factory = DefaultMediaSourceFactory(mediaDataSourceFactory)
simpleExoPlayer = ExoPlayer.Builder(context)
.setMediaSourceFactory(mediaSourceFactory)
.build()
simpleExoPlayer.addMediaSource(mediaSource)
simpleExoPlayer.playWhenReady = true
simpleExoPlayer.prepare()
mBinding?.apply {
playerView.player = simpleExoPlayer
playerView.requestFocus()
}
simpleExoPlayer.play()
}
private fun releasePlayer() {
simpleExoPlayer.release()
}
public override fun onStart() {
super.onStart()
if (Util.SDK_INT > 23) initializePlayer()
}
public override fun onStop() {
super.onStop()
if (Util.SDK_INT > 23) releasePlayer()
}
override fun getLayoutRes(): Int {
return R.layout.layout_dialog_video_view
}
companion object{
fun newInstance(
context: Context,
videoUrl : String,
) : VideoViewDialog{
val dialog = VideoViewDialog(context)
dialog.also {
it.videoUrl = videoUrl
}
return dialog
}
}
}
I tried .stop, clearVideoSurface(), playerView.player = null before .release(). Didn't work

Seems like you called initializePlayer() twice. resulting in two Exoplayer instances playing; you're only able to release the one the simpleExoPlayer variable holds a reference to.

How to change subtile dynamically on PlaybackTransportControlGlue android TV

I am building a video player app for Android TV. I am using Exoplayer leanback dependency as explained in https://developer.android.com/training/tv/playback/transport-controls.
So far I've been able to display the video title, which is static, but I need to display a subtitle that is dynamic, it changes whenever the video playing changes. How can I do it?
The image below shows how the video player looks like. I've used a subtitle phrase as a placeholder on where it should appear.

I was able to solve the problem. I added a listener in the VideoSupportFragment class, Player.EventListener.
This way:
class VideoFragment(mediaItems: Map<String, Any>) : VideoSupportFragment(), Player.EventListener {
private var playerAdapter: ExoPlayerAdapter? = null
private var _mediaItems: Map<String, Any>? = null
private lateinit var mMediaPlayerGlue: VideoMediaPlayerGlue<ExoPlayerAdapter>
private var mItems: List<*>? = null
init {
_mediaItems = mediaItems
}
private val mHost: VideoSupportFragmentGlueHost = VideoSupportFragmentGlueHost(this)
private fun playWhenReady(glue: PlaybackGlue) {
if (glue.isPrepared) {
glue.play()
} else {
glue.addPlayerCallback(object : PlaybackGlue.PlayerCallback() {
override fun onPreparedStateChanged(glue: PlaybackGlue) {
if (glue.isPrepared) {
glue.removePlayerCallback(this);
glue.play()
}
}
})
}
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val mediaSource = _mediaItems?.get("media_source") as Map<*, *>
playerAdapter = ExoPlayerAdapter(activity!!, _mediaItems!!)
mMediaPlayerGlue =
VideoMediaPlayerGlue(activity, playerAdapter!!)
mMediaPlayerGlue.host = mHost;
mMediaPlayerGlue.isControlsOverlayAutoHideEnabled = true
mItems = mediaSource["media_items"] as List<*>
mMediaPlayerGlue.title = mediaSource["title"] as CharSequence?
mMediaPlayerGlue.playerAdapter.setDataSource()
mMediaPlayerGlue.isSeekEnabled = true
playerAdapter?.player?.addListener(this);
playWhenReady(mMediaPlayerGlue)
}
override fun onPause() {
super.onPause()
playerAdapter?.player?.pause()
}
override fun onResume() {
super.onResume()
playerAdapter?.player?.play()
}
override fun onDestroy() {
super.onDestroy()
playerAdapter?.player?.removeListener(this);
}
override fun onMediaItemTransition(mediaItem: MediaItem?, reason: Int) {
if (mItems?.size!! > 1){
val item : Map<*, *> = mItems!![playerAdapter?.player?.currentWindowIndex!!] as Map<*, *>
mMediaPlayerGlue.subtitle = item["subtitle"] as String
}
}
}

When source is empty how to show offline message in exoplayer

I need to catch errors thrown by exoplayer when there is no input or bad stream. If there is no input activity opening showing player with controls nothing is displaying. when there is no input hls source I need to show the alert dialogue that Streaming is offline. How to achieve this. Please help.

private var player: SimpleExoPlayer? = null
private var playerView: PlayerView? = null
private var playWhenReady = true

playerView = findViewById(R.id.player_view)
play()
}
private fun play(){
val trackSelector = DefaultTrackSelector()
trackSelector.setParameters(trackSelector.buildUponParameters().setMaxVideoSizeSd())
player = ExoPlayerFactory.newSimpleInstance(this, trackSelector)
playerView!!.player = player
val dataSourceFactory = DefaultHttpDataSourceFactory(Util.getUserAgent(this, "app-name"))
val uri = Uri.parse("http://localhost:1935/live/mystream/index.m3u8")
val hlsMediaSource = HlsMediaSource.Factory(dataSourceFactory).createMediaSource(uri)

How do I play or pause a video in Exoplayer when using with the ViewPager?

I'm trying to use Exoplayer inside the ViewPager. It will play only when I open it by clicking on the thumbnail which I'm using to display the videos. But it won't play when I reach the page by Scrolling.
I tried calling seekTo(0, 0) & playWhenReady = true inside onPageSelected() and playWhenReady = false inside the onScrolled() methods of the VPAdapter using the Lambdas but didn't work.
Here is the Adapter I'm using for the viewPager.
class MediaVPAdapter(
val context: Context,
#LayoutRes val layoutRes: Int,
val medias: List<MediaFiles> = listOf()
) : PagerAdapter() {
private var player: SimpleExoPlayer? = null
override fun isViewFromObject(view: View, o: Any): Boolean {
return view == o
}
override fun getCount() = medias.size
override fun instantiateItem(container: ViewGroup, position: Int): Any {
return LayoutInflater.from(context).inflate(layoutRes, container, false).apply {
if (medias.isNotEmpty()) {
when (medias[position].mediaType) {
MediaType.PHOTO -> {
// Display the Image
}
MediaType.VIDEO -> {
ssImageView.makeInvisible(true)
exoPlayerView.makeVisible()
player = ExoPlayerFactory.newSimpleInstance(
DefaultRenderersFactory(context),
DefaultTrackSelector(),
DefaultLoadControl()
)
if (medias[position].uri != null)
initPlayer(this, medias[position].uri!!)
}
null -> {
}
}
}
container.addView(this, 0)
}
}
private fun initPlayer(view: View, uri: Uri) {
Timber.i("initPlayer: uri: $uri")
with(view) {
player!!.let {
exoPlayerView.player = it
it.prepare(buildMediaSource(uri), true, false)
it.playWhenReady = false
}
}
}
private fun buildMediaSource(uri: Uri) = ExtractorMediaSource.Factory(
DefaultDataSourceFactory(context, Util.getUserAgent(context, context.getString(R.string.app_name)))
)
.setExtractorsFactory(DefaultExtractorsFactory())
.createMediaSource(uri)
override fun destroyItem(container: ViewGroup, position: Int, obj: Any) {
releasePlayer()
}
private fun releasePlayer() {
if (player != null) {
playWhenReady = false
player!!.release()
player = null
}
}
}
val mediaAdapter = MediaVPAdapter(
this,
R.layout.fragment_media,
true,
medias?.toList() ?: listOf()
)
vpMedia.adapter = mediaAdapter
vpMedia.currentItem = position ?: 0
vpMedia.offscreenPageLimit = 1
If I click on a Video, the selected Video could be played but when I scroll to some other item, none of them were playing. When I try to toggle the Play/Pause button, only the button was toggling.

As far i can see you you code misses the setPlayWhenReady listener.
You should fix it by adding it.setPlayWhenReady(playWhenReady) in the initPlayer method.
