ios - AVPlayer seekToTime only generates frame every second

Question

how can I make AVPlayerLayer display the exact video's frame in method seekToTime.

Now [AVPlayer seekToTime:CMTimeMakeWithSeconds(CMTimeGetSeconds(A, B))], the AVPlayerLayer only displays the frame at every 1-second change for example 1.50-2.50-3.50. I want it to display frame at 4.45 second for example. Is it possible?

Answer 1

您可以使用[AVPlayer seekToTime: toleranceBefore: toleranceAfter:]来获得更高精度的随机媒体访问。
要获得尽可能高的精度，kCMTimeZero请作为两个公差的参数传递。请注意，这可能会在搜索期间增加明显的延迟。
