Cubemap Support for 360 Video

  • Hi,

    that's not possible yet, but support is planed.

    Btw - there will be not much improvement - the claim from Facebook to save 25% by cube-conversion is nonsense!

    They use 'cubesize = spherewidth / 4' for the cubesize calculation - and this is wrong, because that will be an information loss - it's just like downscaling the source image. Correct would be 'cubesize = sphere / PI' for no image resize reduction and no information loss (except of interpolation and rounding errors).

    Here an simple math example where their 25% mainly come from:
    A sphere with 1.000 x 500 => 500.000 pixels
    Cube with width/4: 1.000/4 = 250 => 250*250*6 = 375.000 pixels (=75% of 500.000 = -25%)
    Just fewer pixels...

    Best regards,
    Klaus
