objective-c - 从 NStimeInterval 准确转换为 CMTime

Question

我正在使用两个播放器，一个是 MPMoviePlayerController，另一个是 AVPlayer。每当寻找 MPMoviePlayerController 时，它都会将时间设置为 AVPlayer。一切正常。在将 MPMoviePlayerController 当前时间转换为 CMTime 时，它会四舍五入 ex:(如果 mpplayer 时间为 11.80132，则四舍五入为 11)。

不四舍五入，如何设置AVPlayer的时间？

获取mpplayer时间并发送到AVPlayer类的代码

[avplayerClass  setCurrentTime:[self.videoPlayer currentPlaybackTime]];
NSLog(@"CurrentTime:%f",[self.videoPlayer currentPlaybackTime]);//11.801345

AVPlayer 类中的代码并将时间转换为CMTime

-(void)setCurrentTime:(NSTimeInterval)seekTime
{
    CMTime seekingCM = CMTimeMake(seekTime, 1);
    [self.player seekToTime:seekingCM 
            toleranceBefore:kCMTimeZero 
             toleranceAfter:kCMTimePositiveInfinity];
    [self.player seekToTime:seekingCM];
    NSLog(@"Current time123ns%%%%%%:%f",CMTimeGetSeconds(seekingCM));//11
    NSLog(@"Current time123ns%%%%%%:%f",seekTime);//11.801345
}

Answer 1

试试这个:

  CMTime seekingCM = CMTimeMakeWithSeconds(playbackTime, 1000000);
