Overview
Product summary
Review the store description, core capabilities, and common use cases.
enhanced-h264ify is a fork of well-known h264ify extension for Firefox/Chrome which blocks VP8/VP9 codecs on YouTube, so that you can use H264 only. This may be useful because there are lots of devices on the market which support H264 hardware decoding and do not support VP8/VP9.
This extension has new features such as manual blocking of H264, VP8, VP9, AV1, Opus, AAC codecs and 60fps video. By default it blocks everything but H264 and 60fps video.
It works only on YouTube.

検索して本日から使用しはじめました。結論から申し上げますとインストールした途端、CPUの使用率が5分の1以下になりました。 youtubeを再生しながら作業する事が日常でしたが最近、無意味にCPUの使用率がずっと100％でPC作業が滞っていました。 動画の再生も飛び飛びになり聴いている事も出来ない。 検索したらこのアプリに行き付きました。 インストールするとCPU使用率100％が平均20％程になりました。 助かりました。
古いGPUを使用してるとどうしてもAV1が重く感じてしまうので、この手の拡張機能は便利！！
别用 死垃圾 让我电脑卡死
VP9がどうしても重たくて、AV1で再生したかった為にこちらを導入 AV1のチェックを外し、VP9を強制ブロックさせることでVP9よりも画質が良く、軽くなりとても快適に楽しめてます
cpu usage of chrome on Macbook 14 M2 pro drop 50% when play same video on youtube
great
YouTube'da video izlerken CPU kullanımını etkili bir şekilde düşürüyor. Görüntüden ise çok bir şey kaybolmuyor.
As an old intel Macbook user. I like it very much!! Playing YouTube video VP9 is accelerated by hardware.
Lo mejor del mundo mundial, funciona perfecto
This is a versatile tool which gives control over what codecs will not be sent by YouTube. I use it to block sending AV1 codec. My graphics card is capable of decoding VP9 so that's the codec I get. But the icing of the cake for a person who cares about audio quality is the option to block YT from sending normalized audio streams. The sound of the not normalized streams is better; it has more details and sounds more open. I am so happy with this option.
