ios - AVPlayer wont play video from url in iOS9 -

i trying embed avplayer inside uiview , play mp4 video file url. problem receive black blank view (see screenshot)

in previous ios versions worked me, since upgrading ios9 got problem.

my .h file looks this:

@interface viewcontroller : uiviewcontroller @property (strong, nonatomic) iboutlet uiview *viewplayercontainer; 

whereas in implementation file have following:

@import avfoundation; @import avkit;  @interface viewcontroller ()  @end  @implementation viewcontroller  - (void)viewdidload {     [super viewdidload];      avplayerviewcontroller *playerviewcontroller = [[avplayerviewcontroller alloc] init];      nsurl *url = [nsurl urlwithstring:@"http://techslides.com/demos/sample-videos/small.mp4"];      avurlasset *asset = [avurlasset assetwithurl: url];     avplayeritem *item = [avplayeritem playeritemwithasset: asset];      avplayer * player = [[avplayer alloc] initwithplayeritem: item];      [playerviewcontroller.view setframe:cgrectmake(0, 0, _viewplayercontainer.bounds.size.width, _viewplayercontainer.bounds.size.width)];      playerviewcontroller.showsplaybackcontrols = no;      [_viewplayercontainer addsubview:playerviewcontroller.view];       [player play];   } 

am missing here?

thanks in advance!

@implementation viewcontroller{     avplayerviewcontroller *playerviewcontroller; }  - (void)viewdidload {     [super viewdidload];      playerviewcontroller = [[avplayerviewcontroller alloc] init]; }  - (ibaction)playvideo:(id)sender {     nsurl *url = [nsurl urlwithstring:@"http://techslides.com/demos/sample-videos/small.mp4"];      avurlasset *asset = [avurlasset assetwithurl: url];     avplayeritem *item = [avplayeritem playeritemwithasset: asset];      avplayer * player = [[avplayer alloc] initwithplayeritem: item];     playerviewcontroller.player = player;     [playerviewcontroller.view setframe:cgrectmake(0, 0, self.view.bounds.size.width, self.view.bounds.size.width)];      playerviewcontroller.showsplaybackcontrols = yes;      [self.view addsubview:playerviewcontroller.view];      [player play]; }
