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

Works very well. Youtube now takes less than half the CPU it used to eat re installing this extension. Wonderful ! Thank you very much !
すばらしい。けど4kの動画が720pまでしか見れない。 enhanced-h264ifyも720pまで。 1440pと4kじゃ違いが分からないけど1080pと1440pじゃ画質が違うから1440か4kで見たい。 せっかくこういうの入れて軽くなるのに720pまでしか再生されないんじゃ。 vp9になってからまともに再生されないし、全画面on offするとcpu使用率が100%になっててなかなか全画面のon offが切り替わらないストレスが無くなるけど。なんで1080p以上を見れなくしてしまうかなあ。 I use dual monitor, is that why? I can watch only up to 720p.
супер плагин. спасибо. перестал второй монитор моргать, когда ютюб включен, когда я черчу в автокаде. i3-7167U.
Hace lo que promete, (mi navegador tiene un problema con los codecs pero esto me ayudo con mi problema) asombroso.
работает только на сайте youtube! даже если на каком-то другом сайте встроено видео из ютуба, то это расширение не включается, не действует.
舊電腦硬體的救星 EXCELLENT !!
This extension is good, youtube stopped eating 60+ % CPU, instead consume 5-10% as it should be. HOWEVER I would like option to disable it on live-stream videos, sinice disabling h264 stops them from playing. Cheers for devs
Неплохо, однако существенной разницы с VP9 для FX6300 я не заметил. 1080p60fps без расширения — 25-35%, 3.50ГГц. C расширением абсолютно идентично. Хм.
good thing lul
