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

ممتاز
Awesome extension. You will instantly feel the difference how smooth YouTube videos run sooth
Thank you so much for this ! I never thought I could go back to zero CPU usage in HTML5 just like when using Flash Player ! One question for the developer : can you make a similar one for twitch.tv ? Thanks again.
very useful! no more frame drops like crazy and stuttering video. uses the GPU like video is supposed to do
A must for Toshiba Chromebook 2 (2014), eliminating all the stuttering when watching 1080p 60fps videos on YouTube.
This extension is a must for watching Youtube videos Higher than 1080p on most devices. Its absolutely ridiculous how Google uses VP9 as the default video codec. VP9 Is extremely unoptimized and is extremely demanding. It Only scales to the CPU and not GPU so you'll need a desktop Intel i7 @4Ghz+ in order to run 4k 60fps video. I believe that the fact that Google still Keeps VP9 at default shows how incompetent the Youtube staff is. Keep in mind that the extension Only goes up to 1080p 60fps and 4k standard fps.

good
Before I had to use a extension that forced Youtube to play in flash so I could watch in HD but now that I have this its so much better!
