AVPlayer gives black screen in live stream URL when DAI(Dynamic Ad Insertion) AD load

I have AVPlayer to play live stream URL which is working fine but when DAI Ad load, I got black screen in the player.

I have added notification AVPlayerItemNewAccessLogEntryNotification observer as below:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerItemAccessLogEntry:) name:AVPlayerItemNewAccessLogEntryNotification object:player.currentItem];

When player goes to the black screen, I got the notification event:

-(void)playerItemAccessLogEntry:(NSNotification *)notification {

  DLog(@"VideoWithAdsController:playerItemAccessLogEntry");

 AVPlayerItemAccessLog *accessLog = [((AVPlayerItem *)notification.object) accessLog];

 AVPlayerItemAccessLogEvent *lastEvent = accessLog.events.lastObject;

NSLog(@"The IP address of the server that was the source of the last delivered media segment. = %@",lastEvent.serverAddress);

NSLog(@"A count of changes to the property serverAddress = %ld",(long)lastEvent.numberOfServerAddressChanges);

}

It is printed in console as below:

The IP address of the server that was the source of the last delivered media segment. = (null)

A count of changes to the property serverAddress = -1

I have attached screenshot of black screen. Let me know what is solution.

Thanks in advance.
