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

Супер!!!
Absolute godsend. Without this, YouTube takes 50% CPU and cannot be run alongside a game, since it'll stutter like crazy. With this, YouTube takes maybe 5-10% all the time. Absolutely perfect!
ดีคับ
So good
It would be nice to switch automatically to vp9 for higher res than 1080p, otherwise this extension is free and great !! Thanks for it!
perfecto
Нагрузки на ЦП вообще нет. Только на VIDEO ENGINE видеокарты.
4K非対応 1440xまでしか対応していない。
Stops my loungeroom laptop from annoyingly having its fan go full-bore trying to do 60fps with only an integrated intel chip
It works great but I still don't get it. My iGPU supposes to support vp9 decoding. How is the GPU usage drops significantly when streaming the same video with the same quality setting. VP9 isn't suppose to be resource hungry.
