MPMoviePlayerController无限加载（filepicker）

Question

我正在尝试流式传输上传到filepicker上的视频，但它会在不播放视频的情况下继续加载。

链接是：https://www.filepicker.io/api/file/fLayj5bYTWuso1TVNknv

该页面是一个视频/ mp4页面，但正如您所看到的，该页面没有扩展名。

守则：

@interface RTVideo()
@property (nonatomic,strong) MPMoviePlayerController *moviePlayer;
@end

@implementation RTVideo
UIView *frame;
-(void)play
{
    NSNumber *adId = 5 ;
    NSString *session = [[NSUserDefaults standardUserDefaults]stringForKey:@"sessionID"];
    NSString *type = @"video";
    [NetworkManagerCenter retrievePageWithtype:type
                                    Id:adId
                               session:session
                               success:^(RT *ad) {
                                   [self playAD];
                               } failure:^(NSError *error) {
                                   [self removeFromSuperview];
                               }];
}

-(void)playAD
{
    frame = self;
    NSURL *movieURL = [NSURL URLWithString: @"https://www.filepicker.io/api/file/fLayj5bYTWuso1TVNknv"];
    self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
    [frame addSubview:self.moviePlayer.view];
    self.moviePlayer.fullscreen = YES;
    self.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
    self.moviePlayer.initialPlaybackTime = -1.0;
    [self.moviePlayer prepareToPlay];
    [self.moviePlayer play];
}
@end

这不起作用，因为没有扩展，我该如何解决？
