获取网上流视频总时长和当前播放时长

1.获取网上流视频总时长   

    NSURL *movieURL = [NSURL URLWithString:self.myVideoUrlStr];

    NSDictionary *opts = [NSDictionarydictionaryWithObject:  [NSNumbernumberWithBool:NO]forKey:AVURLAssetPreferPreciseDurationAndTimingKey];

    AVURLAsset *urlAsset = [AVURLAsset URLAssetWithURL:movieURL options:opts];  // 初始化视频媒体文件

    int minute = 0, second = 0;

    second = urlAsset.duration.value / urlAsset.duration.timescale; // 获取视频总时长,单位秒

    if (second >= 60) {

        int index = second / 60;

        minute = index;

        second = second - index*60;

    }

2.当前播放时长

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

    

    NSLog(@"111111111视频播放完毕");

    MPMoviePlayerController *player = [notification object];

    [player stop];

    [[NSNotificationCenterdefaultCenter]

    removeObserver:self

    name:MPMoviePlayerPlaybackDidFinishNotification  object:player];

    NSArray *events = player.accessLog.events;

    int count = events.count;

    //NSLog(@"events count = %d", count);

    for (int i = 0; i < count; ++i) {

        

        MPMovieAccessLogEvent *currenEvent = [events objectAtIndex:i];

       // double byts =  currenEvent.indicatedBitrate ;

       // NSLog(@"5555555==视频播放当前时间======%f",currenEvent.durationWatched);

        videotimedurationWatched = currenEvent.durationWatched;

    }

}
