pixelDensity with more than value 1 doesn't work

[jay-afrisando]

I attempted to use pixelDensity with more than value 1, for example pixelDensity(2) or pixelDensity(3). I used p5.rec locally. The browser console shows more than one attempts of getting frames, for example "got 240 frames" and "got 1 frame"—both are consecutively followed by "loading ffmpeg", so there are two times of it. Eventually the console returns error.
