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

Жаль что только видело 60 фпс блочит, видео 50 фпс игнорит(( И вообще всего пару дней проработал, а потом перестал работать, и совсем не блочит 60 фпс(( И удаляла-заново устанавливала расширение и в настройках пыталась копаться. Всё безуспешно(( Не знаю что и делать приходится снова на ютубе смотреть видео в качестве 480((((
I got a new chromebook but still had issues with youtube on 1080p, running smooth at 60fps now. I appreciate this extension
It works. :D Thanks. Finally I can watch a YouTube video with more than 480p quality. :D
полезное расширение
Great extension for telling youtube to serve your device with MP4/AVC codec videos instead of google's VP Codec. It is sad though as this functionality should be built-in within Google Chrome for better user experience in Youtube. AMD's Polaris video cards or older devices don't have hardware acceleration for VP codec
Для меня плагин решил проблемы с подвисанием видео на ютубе на celeron n3350
Lovely, small extension that does what it promised. I have had it for a few years now and my 10-year-old Laptop (bless it's CPU. RIP...) couldn't play 1080p videos on Youtube without gasping for air. With this, no problem. I still use it with my new machine. The only small thing I would like for it to include is either a support for resolutions over 1080 on YT (I am not sure H.264 can do it) or with higher res to just have an option to ignore the settings. If I want to watch a video in 4K (rarely, but still), it'd be nice to be able to without having to disable the extension.
Excellent! :)
I think this extension kills all my 4K viewing. I thought youtube has removed all the 4K content.
Lately I've been watching Youtube a lot. I always thought CPU usage seemed unreasonable compared to say a similar res MP4 file. A couple minutes of research and i landed on this extension. The VP9 CPU decoding reason totally made sense. Great for my lap since I use my laptop on it -it's running much cooler now! Should be better for battery life too.
