h264ify

Makes YouTube stream H.264 videos instead of VP8/VP9 videos

h264ify - Stream YouTube Videos in H.264

"h264ify" is a Microsoft Edge add-on that optimizes YouTube video streams by forcing them to use H.264 encoding instead of the default VP8/VP9. This is especially useful for users with less powerful hardware, as H.264 is generally hardware accelerated by GPUs. By reducing CPU usage, it helps prevent stuttering, overheating, and excessive battery consumption. Note that 4K and 1440p resolutions are not available in H.264 format.
