得到一个当前正在播放的视频的帧速率 [英] getting the frame rate of a currently playing video

问题描述

我想知道 - 有没有办法让一个Android videoView目前效力于该帧速率。我看着VideoView类别的文档，但它是无济于事。有一些其他的方式来做到这一点？

I was wondering - is there a way to get the frame rate at which an Android videoView is currently playing. I looked into the documentation of the VideoView class but it was to no avail. Is there some other way to do this?

感谢。

推荐答案

当然可以。

VideoView扩展视图，所以你会做延伸VideoView自己YourVideoView类中，实现的onDraw方法，调用super.onDraw那里，也有执行你的FPS计算。

VideoView extends View, so you'd make your own YourVideoView class which extends VideoView, implement onDraw method, call super.onDraw there, and also performing your FPS computation there.

所以，你可以自己算多少次谢胜利的onDraw被调用VideoView。它显示你需要的地方（屏幕/ logcat中/ ...）。

So you can count yourself how many times in secound onDraw is called for VideoView. Display it wherever you need (on screen / logcat / ...).

计数的帧率是另一回事，你可以看看这里简单的例子。

Counting framerate is another story, you can look for simple example here.
