在AVPlayer seekToTime中使用秒 [英] Using seconds in AVPlayer seekToTime

问题描述

这应该很简单.我有一个AVPlayer播放视频文件，我希望能够跳到特定时间，但是在理解CMTime的工作方式时遇到了一些麻烦.

this should be a simple one. I have an AVPlayer playing a video file and I want to be able to jump to a specific time but I'm having some trouble understanding how CMTime works.

我需要指定时间(以秒为单位).例如:如果我想跳到第二个10.8，我想做这样的事情:

I need to specify the time in seconds. For example: if I wanted to jump to second 10.8 I'd like to do something like this:

[self.avPlayer.currentItem seekToTime:CMTimeMakeWithSeconds(10.8, 1];

但是我没有得到想要的结果.

But I'm not getting the result I want.

可能会让您更清楚地了解CMTime.

Might give you a clearer idea of CMTime.

如果您将行更改为读取...

If you changed your line to read...

[self.avPlayer.currentItem seekToTime:CMTimeMakeWithSeconds(10.8, 60000)];

您可能会获得更好的结果. 60000是一秒内构成多少个项目.如果将1用作该值，则每秒只能跳到一个位置-通过放置60000，您将在10秒和11秒之间给自己60000个位置.

You might get better results. The 60000 is how many items make up a single second. If you use 1 for this value then you can only jump to a single place per second - by putting 60000 you are giving yourself 60000 places between second 10 and second 11.
