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

Mükemmel...
THANK YOU SO MUCH
расширение снизило несколько процентов хорошее,видео загружает лучше,неплохо
Very good. My laptop is Broadwell, so vp9 is taxing and makes my laptop hot. This help lower the temp around 5-10 degree celsius.
Ещё больше грузить стало процессор. Раньше хоть было 60-100% загрузка, а теперь вечно 100% да ещё и памяти расширение отожрало. Ноль толку.
I am using Ryzen 3200g 8gb ram CPU usage is now below 100% while playing YouTube and a CPU-intensive game, thank you.
Amazing! My old laptop has problem with playing 720p 60 FPS but with this It can play 1080p 60 FPS without any problems.
No longer really helps performance. Don't use this unless you're on a particularly bad PC that struggles with VP9. Using the extension butchers video playback on my more modest Windows 10 PC (12GB RAM, 1050Ti, i5-3470), so I'm assuming this'll only help especially ancient PCs.
U S E F U L
Lenovo C330 just could not play 080p 60fps youtube videos. This extension fixed it! Grateful!
