![我的 Firefox 配置中有什么导致 YouTube 无法预缓冲?](https://linux22.com/image/1515699/%E6%88%91%E7%9A%84%20Firefox%20%E9%85%8D%E7%BD%AE%E4%B8%AD%E6%9C%89%E4%BB%80%E4%B9%88%E5%AF%BC%E8%87%B4%20YouTube%20%E6%97%A0%E6%B3%95%E9%A2%84%E7%BC%93%E5%86%B2%EF%BC%9F.png)
我为我的 Firefox 创建了一个“用户配置”文件来提高安全性和性能,但我发现 YouTube 仅在到达当前缓冲内容的末尾时才会继续缓冲,这会导致整个视频出现严重中断,有人能告诉我哪个是错误的吗?
这是的开始pref.js
:

答案1
您需要的是一个用于禁用 dash 播放的脚本。 使用 YouTube 中心插件
然后,您应该会在 YouTube 主页上看到一个齿轮图标。单击该图标,然后在外部播放器下取消勾选 Dash 播放。 Dash 播放设置
Dash 播放的功能是在播放视频时对其进行缓冲。这可能会导致很多缓冲问题。
答案2
在地址栏中输入about:config
~ 单击Accept
。在搜索栏中输入mp4
- 你会找到media.mediasource.mp4.enabled
,将其设置为false
。
这将解决 YouTube 视频问题。一些播放视频的网站需要启用它,因此需要true
再次设置才能使这些视频正常工作。这是 Adobe Flash、HTML5 的东西。因此,创建一个文本文件夹,并使用我提供的信息将其设置在桌面上,这样如果您将来需要此信息,您就可以获得它。请记住,这about:config
是 Firefox 浏览器的核心,所以除非您知道自己在做什么,否则不要更改其中的值,否则它会让 Firefox 不高兴。哈哈!希望这对您和所有人有所帮助!问候!
