Reduce Browser's Energy Impact for playing YouTube Video
目前為
Inspired by kona's YouTube CPU Tamer
This is for all kinds of YouTube applications, including main page, embedded video, and live chat.
- Faster
- More Stable
- Lower Battery Consumption
Note1: This hijacks to setTimeout, setInterval, clearTimeout, clearInterval
Note2: This uses setInterval(..., 250ms) instead of requestAnimationFrame for background running.
This userscript hijacks setTimeout & setInterval leading different browser behaviors as follows:
let f=function(){console.log('hello world')};
setTimeout(f,100);setTimeout(f,100);setTimeout(f,100);
Native: print out "hello world" 3 times.
Modified: print out "hellow world" 1 time. (in the same AnimationFrame)
let f=function(){console.log('hello world')};
setTimeout(f,100);setTimeout(f,110);setTimeout(f,120);
Native: print out "hello world" 3 times.
Modified: print out "hellow world" 1 ~ 3 time(s) depending on the execution time of function handler, the responsiveness of browser, and the segregation of AnimationFrames;
let f=function(){console.log('hello world')};
setTimeout(f,100);setTimeout(f,200);setTimeout(f,300);
Native: print out "hello world" 3 times.
Modified: print out "hello world" 3 times. (in 3 AnimationFrames)
