从NStimeInterval到CMTime的精确转换

Question

我使用两个播放器，一个是MPMoviePlayerController，另一个是AVPlayer。无论何时查找MPMoviePlayerController，它都会将时间设置为AVPlayer。一切都很正常。将MPMoviePlayerController当前时间转换为CMTime时，会舍入ex：(如果mpplayer时间为11.80132，则舍入为11)。

如果不进行四舍五入，如何将时间设置为AVPlayer

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);
