YouTube如何防止屏幕保护程序在视频播放过程中出现？ （视窗） [英] How does YouTube prevent the screensaver from showing up during video playback? (Windows)

问题描述

我注意到，当我在YouTube上观看视频时，屏幕保护程序不启动。
我正在使用Windows 7。

这是测试：
$ b $ ol

将Windows屏幕保护程序设置为1分钟。

浏览到YouTube并播放超过1分钟的视频;

请注意，您的屏幕保护程序在指定时间（1分钟）后不会启动。

我测试过使用Firefox，Chrome和IE8。我的Flash Player版本是10.3。 （Youtube使用闪光灯播放视频）。无论我是否全屏观看视频，都会发生同样的情况。

有人知道他们是怎么做的吗？

我已经搜索过，但是我发现所有人都说这是不可能的，或者提示用户在观看视频时禁用他们的屏幕保护程序。

解决方案

有人在StackOverflow之外指出我这篇文章： http：//www.webkitchen .be / 2010/04/13/6-less-known-features-in-flash-player-10-1 /

全屏模式下禁用的屏幕保护程序

没有比每隔几分钟按下键盘或移动鼠标防止屏幕保护程序在全屏观看视频时踢入。如果视频正在播放，而不是暂停，停止或缓冲，则Flash Player 10.1暂时禁用屏幕保护程序。但它也适用于音频。所以...如果你正在运行一个播放音频的全屏应用程序，它不会暂停，停止或缓冲，实际上已经有音量的屏幕保护程序不会踢。

很遗憾，我找不到官方的Adobe来源。他们似乎非常专注于Flash Player 11，他们删除了自Flash Player 10以来的新功能列表。

我测试了这个，全屏或不显示，只要视频正在播放。

我想我的原始问题的答案是 NOTHING 。 Flash Player，不是YouTube，会自动执行。

I have noticed that mi screensaver doesn't start while I'm watching videos on YouTube. I'm using Windows 7.

This is the test:

1. Set Windows screensaver to 1 minute.
2. Browse to YouTube and play a video longer than 1 minute; ideally much longer.
3. Note that your screensaver doesn't come up after the specified time (1 minute).

I've tested using Firefox, Chrome and IE8. My Flash Player version is 10.3. (Youtube is using flash to play the videos). The same happens whether I watch the video in full-screen or not.

Does anyone know how they do it?

I've searched but all I found was people saying it's not possible, or tips for users to disable their screensaver while watching videos.

Disabled screen saver in full screen mode

There’s nothing more annoying than having to press the keyboard or moving your mouse every few minutes to prevent the screensaver from kicking in while watching a video in full screen. Flash Player 10.1 now temporarily disables your screensaver if video is playing and not paused, stopped or buffering. But it also works with audio. So… if you’re running a full screen app that plays audio and it is not paused, stopped or buffering and actually has volume the screensaver will not kick in.

Unfortunately I cannot find an official Adobe source for this. They seem to be so focused on Flash Player 11, that they removed the list of "new features" available since Flash Player 10.

I tested this and it works whether in full screen or not, as long as a video is playing.

I guess the answer to my original question is NOTHING. Flash Player, not YouTube, does it automatically.
