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.

Executa muito bem o seu propósito. Recomendo a quem tem um notebook fraco ou antigo e sofre com superaquecimento ao assistir vídeos no YouTube.
Расширение перестало работать на youtube. Теперь воспроизводится через кодек avc1.640028
Works like a charm. Thank you!
Excellent!
It works: doesn't prohibit 4K or 60fps video streams like h264ify and decreases CPU use vs av01. For some reason the Chrome flag at chrome://flags/#enable-av1-decoder appears to have been removed or is missing for me and the setting "Prefer AV1 for SD" at https://www.youtube.com/account_playback under "AV1 settings" is not persistent and automatically reverts to "Auto (recommended)" after a few sessions. I had no other way to disable av01 in favour of vp09. Thank you.
out of the box .
Hace lo que promete y lo hace perfecto.
Right now, it's the only way I can block AV1. Thanks!
Я поставил расширение enhanced-h264ify использую Яндекс браузер, в настройках расширения выключил кодек VP9 и УРА!!! все заработало без тормозов и мой нетбук ожил. Видяха начала обрабатывать 1080р правда всё что выше пропало из настроек качества. Если нажать правой кнопкой на ролик и включить "Статистику для сисадминов" будет видно что видео стало обрабатываться кодеком "avc1" его мой слабенький комп еще переваривает. Удачного всем просмотра без тормозов :-)
works well
