Overview
Product summary
Review the store description, core capabilities, and common use cases.
Try h264ify if YouTube videos stutter, take up too much CPU, eat battery life, or make your laptop hot.
By default, YouTube streams VP8/VP9 encoded video. However, this can cause problems with less powerful machines because VP8/VP9 is not typically hardware accelerated.
In contrast, H.264 is commonly hardware accelerated by GPUs, which usually means smoother video playback and reduced CPU usage. h264ify makes YouTube stream H.264 videos instead of VP8/VP9 videos.
Note: 4K and 1440p videos will not be available because YouTube no longer encodes those videos in H.264

good is working
youtube videolarında işlemci kullanımı oldukça düşüyor laptop sessiz çalışıyor
Ho un pc abbastanza performante, il mio vero problema era che la mia connessione (2 Mbit download) permette di vedere senza buffering i video in 720p a 30 fps ma non a 60. L'estenzione funziona perfettamente.
Thanks for allowing my pc's to use my hardware decoder(s)!
EXTENSION NEEDS UPDATE! When block 60fps is enabled it caps the video quality at 720p. PLEASE FIX! I am unable to play 1080p 60fps smoothly. This problem has been happening since October.
57だと重かったのですが58で軽くなりました。 VP9デコード対応してない方は必須の拡張機能です。 自分はHD4400オンボなので当然webMのGPU支援効かないので此方でmp4にしたら 1080p60fpsでもほぼCPU使わず見れてます。 ※ライブ配信もmp4になります。 ※最新のグラボ GTX1000シリーズやIntelHD620以降使ってる人はyoutubは普通に見たほうが軽いです。此方の拡張機能は古いGPUなどでVP9が重い場合の救済策なので
Love it. My chrome is stutter on 60fps but not now!
Ubuntu on AMD laptop. I use h264ify with hardware enabled Chromium(VA-API). Works great.
Excellent. I hate 60 FPS videos anyway and given that my laptop's lowly HD 4000 can only do hardware accelerated decoding of h264 videos, this extension is a must. Thanks.
works for me on a ubuntu nvidia laptop better performance and less cpu usage
