ios AVPlayer failed to stream remote video -

-

i have avplayer plays video remote url.

here code:

avplayeritem* playeritem = [avplayeritem playeritemwithurl:videourl]; self.player = [avplayer playerwithplayeritem:playeritem]; self.player.actionatitemend = avplayeractionatitemendnone;  avplayerlayer *playerlayer = [avplayerlayer playerlayerwithplayer:self.player]; playerlayer.frame = playerview.bounds; [playerview.layer addsublayer:playerlayer];  [self.player play];

when start stream have less second video chunck , downloading stops , nothing happens.

mpmovieplayercontroller , browser plays video usual.

i doubt, might effect of cropping video (because videos without cropping works fine). here guide use crod video http://www.one-dreamer.com/cropping-video-square-like-vine-instagram-xcode/

also clean app same setup can't play video.

any ideas? thanks!

use avplayeritemplaybackstallednotification

 [[nsnotificationcenter defaultcenter] addobserverforname:avplayeritemplaybackstallednotification object:nil queue:[nsoperationqueue mainqueue] usingblock:^(nsnotification *note) {         [weakself performblockonmainqueueafterdelay:1.5 block:^{             [weakself.player play];         }];     }];
