Add remote actions to PiP

If you want to add controls (play, pause, etc.) to your PiP window, create a RemoteAction for each control you want to add.

1. Add constants for your broadcast controls:

   // Constant for broadcast receiver
   constvalACTION_BROADCAST_CONTROL="broadcast_control"
   // Intent extras for broadcast controls from Picture-in-Picture mode.
   constvalEXTRA_CONTROL_TYPE="control_type"
   constvalEXTRA_CONTROL_PLAY=1
   constvalEXTRA_CONTROL_PAUSE=2
   PictureInPictureSnippets.kt 

2. Create a list of RemoteActions for the controls in your PiP window.
3. Next, add a BroadcastReceiver and override onReceive() to set the actions of each button. Use a DisposableEffect to register the receiver and the remote actions. When the player is disposed, unregister the receiver.

   @RequiresApi(Build.VERSION_CODES.O)
   @Composable
   funPlayerBroadcastReceiver(player:Player?){
   valisInPipMode=rememberIsInPipMode()
   if(!isInPipMode||player==null){
   // Broadcast receiver is only used if app is in PiP mode and player is non null
   return
   }
   valcontext=LocalContext.current
   DisposableEffect(player){
   valbroadcastReceiver:BroadcastReceiver=object:BroadcastReceiver(){
   overridefunonReceive(context:Context?,intent:Intent?){
   if((intent==null)||(intent.action!=ACTION_BROADCAST_CONTROL)){
   return
   }
   when(intent.getIntExtra(EXTRA_CONTROL_TYPE,0)){
   EXTRA_CONTROL_PAUSE->player.pause()
   EXTRA_CONTROL_PLAY->player.play()
   }
   }
   }
   ContextCompat.registerReceiver(
   context,
   broadcastReceiver,
   IntentFilter(ACTION_BROADCAST_CONTROL),
   ContextCompat.RECEIVER_NOT_EXPORTED
   )
   onDispose{
   context.unregisterReceiver(broadcastReceiver)
   }
   }
   }

4. Pass in a list of your remote actions to the PictureInPictureParams.Builder:

   valcontext=LocalContext.current
   valpipModifier=modifier.onGloballyPositioned{layoutCoordinates->
   valbuilder=PictureInPictureParams.Builder()
   builder.setActions(
   listOfRemoteActions()
   )
   if(shouldEnterPipMode && player!=null && player.videoSize!=VideoSize.UNKNOWN){
   valsourceRect=layoutCoordinates.boundsInWindow().toAndroidRectF().toRect()
   builder.setSourceRectHint(sourceRect)
   builder.setAspectRatio(
   Rational(player.videoSize.width,player.videoSize.height)
   )
   }
   if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.S){
   builder.setAutoEnterEnabled(shouldEnterPipMode)
   }
   context.findActivity().setPictureInPictureParams(builder.build())
   }
   VideoPlayer(modifier=pipModifier)
