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

После обновления Chrome 62, воспроизведение видео останавливается при сворачивании браузера и, в конечном итоге, плеер выдает ошибку.
