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

h264ify - Stream YouTube in H.264

h264ify is a Chrome extension that makes YouTube videos stream in H.264 format instead of VP8/VP9. This optimization benefits users with less powerful devices by reducing CPU usage, preventing stuttering, and saving battery life, as H.264 is generally hardware accelerated. Note that 4K and 1440p videos are not supported as YouTube does not provide these resolutions in H.264. For smoother video playback, try h264ify!

와 진짜 혁신이다. 솔직히 tv 유툽용으로 최신컴 사기 진짜 아까운데 이 앱 하나로 구형컴으로 유튜브 볼수 있음. 그것도 저전력으로, 강추! 당연히 4k부터는 h.264 코덱이 지원 안함. FHD 60hz 까진 똥컴으로 문제없음.
