Summary
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.
