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.

thank you its uses GPU's decoding video system instead of the slowest CPU decoding video system now i can play 1080p60 without any problem (unless your computer is cooled properly) this is recommended for a user with a slow CPU thank you! i love it
Windowsタブレットで使っています。H264のハード再生支援で動作が軽くなリ、高音質(opus対応)なので非常に快適です。
good

perfeito
Works!
Расширение должно стоять по умолчанию. Кодек VP9 - угроза экологии нашей планеты, слишком чрезмерную дает нагрузку на современные процессоры, заставляет утилизировать старые.
Excellent! Fixed my high CPU usage issues on viewing YouTube vids w/Chrome.
cumpre o que promete
こっちだとvp9ブロックしても音声コーデックはopus優先で再生される
