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

h264가 1080p 상위에 있는 화질을 지원하지도 않는데, 강제로 1080으로 만든다는 무식한 사람들 때문에 댓글 담. 유튜브에서는 1440부터는 h264지원안한다. 안되면 검색이라도 좀 하셈.
works as advertised, chromebook performance greatly improved, thanks
ничего не изменилось, ютуб лагать не перестал
Расширение Норм! но два дня назад пропало качество 720р !! Стримы на Ютубе смотрю в 480р !выше не далается! видосы всё норм 720р!!! ??????
как грузит ,так и грузил
it doesn't do anything
This 100% cured my buffering issues. I am running a somewhat low performance arm based ChromeBook and it could not handle any video over 480p without buffering every 5 seconds, but now I can easily stream full 1080p on YouTube with VERY FEW dropped frames, to the point where you cannot tell. (~1 in 900 frames) this extension is very effective and I highly recommend it.
Extensão milagrosa criada por Deus.
Does not work. 360p 100% CPU Athlon X2 5200+ The extension probably only works on hardware released no later than 5 years ago. It's a shame that YouTube doesn't use compression that doesn't require much processing power. Any video downloaded to my computer runs perfectly in 1080p in the media player. Why can't this be done in a web browser?
Bring it to Safari please, desperately needed!
