关于 SmartPlay for Safari 的使用问答

Q.SmartPlay for Safari 是免费的还是需要订阅?有没有隐藏扣费?

SmartPlay for Safari 在 Apple App Store 上是 100% 完全免费下载的,且无需任何隐藏按周付费订阅。您可以在 Mac 和 iPhone 的 Safari 浏览器上放心使用。

Q.如何在 Mac 和 iPhone 的 Safari 浏览器中启用 SmartPlay for Safari?

在 Mac 上:从 Mac App Store 下载后,启动一次该应用,随后打开 Safari 浏览器 -> 顶部菜单选择【设置】(Settings) -> 点击【扩展】(Extensions) 标签页 -> 找到“SmartPlay for Safari”并勾选复选框即可启用。 在 iPhone/iPad 上:打开系统【设置】 -> 向下滑动点击【Safari 浏览器】 -> 选择【扩展】 -> 点击“SmartPlay for Safari”并将其开关切换为【开启】。

Q.使用该扩展可以在不购买视频会员的情况下使用画中画 (PiP) 吗?

是的。该扩展直接调用 WebKit 底层的原生画中画 API,绕过了部分网页播放器人为限制的收费壁垒,让您在任意网页免费启用画中画悬浮播放。

Q.高倍速播放(如 2.0x 或 3.0x)时声音会变调尖锐吗?

不会。WebKit 原生集成了高质量的音调补偿算法(Pitch Preservation),即使在 2.5x 或 3.0x 倍速下,人声依然清晰自然,绝不会变成尖锐的“花栗鼠”声音。
