iOS AVPlayer seektotime 精准定位

释放双眼,带上耳机,听听看~!

seekToTime精准定位

原因分析:

关于这个seektotime,是个坑,拖动进度条跳转的时候,比如跳到10秒,结果跳到了6秒或者8秒,很奇怪!seektotime跳转不准确。。。

解决办法:

使用这个方法 seekToTime:toleranceBefore:toleranceAfter:

通过设置偏差tolerance,来精确设定跳转的误差。

官方解释

/*!
@method            seekToTime:toleranceBefore:toleranceAfter:
@abstract          Moves the playback cursor within a specified time bound.
@param             time
@param             toleranceBefore
@param             toleranceAfter
@discussion        Use this method to seek to a specified time for the current player item.
The time seeked to will be within the range [time-toleranceBefore, time+toleranceAfter] and may differ from the specified time for efficiency.
Pass kCMTimeZero for both toleranceBefore and toleranceAfter to request sample accurate seeking which may incur additional decoding delay.
Messaging this method with beforeTolerance:kCMTimePositiveInfinity and afterTolerance:kCMTimePositiveInfinity is the same as messaging seekToTime: directly.
*/
- (void)seekToTime:(CMTime)time toleranceBefore:(CMTime)toleranceBefore toleranceAfter:(CMTime)toleranceAfter;

示例代码

    [_player seekToTime:playTime toleranceBefore:CMTimeMake(1, 1000)
toleranceAfter:CMTimeMake(1, 1000)];

共同学习,留念备忘
